Beschorneria septentrionalis

In March of 1991, Martin Grantham, horticulturist in charge of the Mezo-American Garden at the University of California Botanical Garden at Berkeley; Eduardo Estrata Castillon, student at the College of Forestry Science at the State University of Nuevo Leon, Linares, Mexico; and Carl Schoenfeld of Yucca Do Nursery, accompanied me on a botanizing expedition to northeastern Mexico to observe Magnolia tamaulipana at its northern location in the Sierra Madre Oriental, approximately seventy miles north of Ciudad Victoria. It was much to our surprise and delight that while driving through a pine oak forest, we first saw the Beschorneria in flower. It had bright red and green cylindrical bell-shaped blooms held on glossy scarlet four-foot-tall stalks that were exceptionally exotic. The stalks emanated from a base of dark green, strap-like, evergreen foliage. Although this agave-relative had been identified and named in literature in 1987, it represented a rare find to be shared with the world of horticulture.

Two plants were collected: one was planted at Peckerwood Garden and has thrived under shaded conditions with some moisture; the other was sent to the Botanical Garden at Berkley for testing and hybridization. In August of the same year, I returned to the same site to collect seeds that were shared with the late Dr. J. C. Raulston (North Carolina State University Arboretum) and Yucca Do Nursery. These plants have proven cold hardy to -4°F, flowered healthy blooms, and produced viable seeds. In the mid 1990’s Martin Grantham made crosses between B. septentrionalis and B. yuccoides, and many of these sturdy hybrids are being tested at Peckerwood Garden. Their foliage is rich green, washed with silver frosting. We have not experienced a typical winter “blue norther” for several years; therefore we can not report on cold hardiness. In early May, 2000, three of these plants that are being tested in a sunny location flowered. The blossoms were showy and very similar to the B. yuccoides parent.

The Mystery Magnolia

Searching for plants in the mysterious and magical mountains of the Sierra Madre Oriental of Mexico is an arduous and challenging experience, but it is also exhilarating and exciting. It is a layering of time — past, present, and future. The patchwork of people, places, plants and events form an integral composition that has become a way of life.

The mountains of northeast Mexico are rich in natural beauty — spaces that are awesome and breathtaking — and the dramatic environmental changes which occur on the eastern side of this range have produced a variety of amazingly diverse habitats that are rich in numbers of plant species. It is not unusual to find dogwoods growing in a moist canyon on the northeast side of the mountain and walk only a few feet to see agaves and yuccas thriving on a hot and dry western slope. These phenomenal changes also occur when climbing in altitude. The myriad forms, colors, and textures of this exotic array of plants unfold into an unbelievably beautiful landscape that is indeed an intense experience.

Being at the right place at the right time is an important factor in searching for plants. We have rarely returned from one of our numerous expeditions without being able to report the discovery of a new plant with potential use. Frequently it was found in an area that we had explored time and time again, but it was another season and a different time of day. Natural light effects our lives in a multitude of wonderful ways.

Learning how to listen is also of utmost importance on a botanizing expedition. Just a few words about a place or a plant family from someone you meet along the way or a traveling companion can open a whole new field of interest. During the past six years, we have made the opportunity to travel with many wonderful persons from various areas of this country and abroad — some very young; others old, wise and experienced; and some even more eccentric than we. All have been very knowledgeable and anxious to share. Through this complex layering process, we have gleaned much botanical, horticultural, geological, and cultural information, but above all else, each of these personalities has had an important impact on our lives. What a great way to learn.

In January of 1990, on the recommendation of Mark Kane (at that time associate editor of Fine Gardening), a research team sponsored by the Arnold Arboretum of Harvard University contacted us regarding a proposed expedition to the Sierra Madre Oriental. The purpose of this expedition was to collect samples of Taxus globosa to be used in a cancer research project sponsored by the National Cancer Institute. Their previous venture into the area to locate taxus had ended in failure; therefore, to insure that this expedition would be a success, during the summer of 1990, we purchased maps that had been compiled and printed by the Mexican government during the 1970’s. Several of these maps proved most informative because they recorded vegetation with reference to specific areas. By plant family name association, we were able to locate several new colonies of Taxus globosa. To our surprise we noted that Magnolia grandiflora is listed in this plant inventory. Could this information possibly be correct, or is it just another botanical error? This mystery magnolia stimulated much excitement and haunted our thoughts, but many months and events passed before there was time to look further into this intriguing information.

The College of Forestry Science at the State University of Nuevo Leon, in Linares, arranged for Eduardo Estrada-C., a biology student, to accompany us on this expedition to collect Taxus globosa. In mid-October of 1990 we were joined by Lalo, as Eduardo is called by his friends, and headed off on this memorable quest. We had spent long hours studying maps and untold days in late summer locating and maneuvering through uncharted networks of narrow, rocky roads and paths that lead to higher elevations where taxus grow. As a result we were able to quickly lead the research team to large stands of healthy trees. We located five colonies of this potentially important small tree and the researchers collected foliage and branch samples from over fifty trees for testing. We have never been privy to the information concerning exact figures on the taxol content of these samples, whatever happened to the rooted cuttings made from some of these collections, or just who is to benefit from this project. It is hoped that in the future it will be Mexico.

At 8:45 a.m. on a balmy day in mid-December 1990, accompanied again by Lalo, we leave the town of Linares and head south to search for a road that will lead us into a rugged mountain range where Magnolia grandiflora is reported to grow.

These high altitude mountains that we are so eager to investigate are approximately 75 miles northwest of Ciudad Victoria, Tamaulipas. If indeed there are magnolias here, this location would be approximately 125 miles north of the evergreen magnolias found at Rancho del Cielo Biosphere Reserve at Gomez Farfas, Tamaulipas. This mountain range is positioned so that the peaks and valleys form windows and doors with direct access to the Gulf of Mexico. The coastal breezes sweep into these areas and produce heavy fog during the dry months and an abundance of rain in late summer and early fall. On numerous occasions we have observed these distant mountains shrouded in clouds. The question is, how does one get into these remote areas that are possibly supporting cloud forest with great potential for new species? Our antiquated maps show what could be a small road or a trail in the lowlands, but at higher elevations it is impossible to separate road and trail from contours. One way or another, we are determined to explore the mystery of this magnolia.

Around 10:00 a.m. we turn off one of the major highways leading south and slowly make our way over a one lane dirt road that leads to a small village at the edge of a river. Here our map indicates that this road will cross the river and begin climbing into the mountains.

The previous summer had been unusually dry; therefore, the endless scrub and thorny brush that surround and arch over both sides of the road are heavy with gray-brown dust. The surface of the road is very bumpy, and often we are forced to drive so slowly that the wind carries the dust made by our tires ahead of the vehicle. Like the trees and shrubs, every inch of the truck, its contents, and all occupants are quickly covered in talcum-like dust. There are few incentives to linger in the parched lowlands because we are excited by the prospect of making our way into the cool and green mountains.

The road enters the village where we slow to a crawl to get our bearings and to admire the beautifully crafted dwellings. There are ten or so families living in this communal ejido which is perched high on a mesa overlooking a clear, swift-flowing river and the distant mountains. When we reach the far end of the village, it quickly becomes apparent that there is no river crossing here. The remains of what had been a road are visible on both sides of the river, but floods have eroded the banks and cut deep holes in the river bed. There is an abrupt ten foot drop between the old road and the river’s edge. Not even our four wheel drive vehicle with its heavy duty tires could maneuver this. Everyone in the village comes out to greet us, question our needs, and assist with information on where and how to get to the other side of the river. Needless to say, Lalo receives numerous conflicting directions.

Lalo does a great job of interpreting the bits and pieces of information and, after several wrong turns, we reach another nearby village. Here we ask directions from only one person, and within minutes we drive down to the edge of the cold, crystal clear river. Ancient Mexican cypresses (Taxodium mucronatum) with massive trunks and far spreading branches line the river bank. We safely ford the river with water lapping at our car doors, foolishly thinking that the worst is behind us and that it will soon be possible to begin our ascent to higher elevations. As soon as we leave the river bed and its far bank, we encounter three forks in the road, each well worn to the same degree. We choose the one to the right, because it seems to head toward the mountains. It is the wrong choice, and as the day progresses, we make many other wrong decisions. We give a man who has been milking his herd of goats a short ride. Oh, how good that still warm milk smelled to us all, and for a short time he had us headed in the right direction. For miles the narrow road leads through a dense and impenetrable jungle of small trees, shrubs, and vines that obscure the mountains and make it visually impossible to determine our orientation.

Occasionally we see small trees that have pushed their branches above the thicket, and these umbrella-like canopies are laden with winged seed pods that are brilliant wine-red. Contrasted with the glossy dark green foliage they make a dazzling show in the morning light. We recognize these trees as Wimmeria concolor and note the approximate location in our journal.

“We had no idea that this outstanding ornamental is found this far north, and this information alone would have made the expedition worthwhile.”

All are about ready to give up, when suddenly the road surface changes from powdery dry dust to bouncy pebbles. Abruptly we begin our climb and there is a dramatic change in vegetation. The trees are taller and there are spaces between them. Mighty stone formations rise into view. Someone notes a Quercus polymorpha, the handsome and tenacious oak which has blue green foliage and grows from Guatemala to Texas. It is well past noon, we have traveled approximately 11 miles beyond the river and have reached 1,400 feet altitude. At long last, the air is fresher and cooler, and there are views into distant canyons and mountains. On the high ridges above, growing from within crevices in the stone, there are hundreds of palms (Brahea edulis) piercing the skyline.

We stop briefly to examine the glossy, dark green leaves of an orchid tree (Bauhinia sp.). Legumes are one of Lalo’s major interests and this small tree is of special concern because he thinks that it could be a new species. He took a herbarium pressing of the leaves, but, at last report, this plant is still unnamed. At this location we see Clethra pringlei, a small evergreen tree that in mid-summer flowers spectacular racemes of white, urn-shaped flowers with fragrance reminiscent of cinnamon and honey followed by deep pink fruit that slowly turns brown with maturity. The tree is familiar because we have seen it at Rancho del Cielo Biosphere Reserve. We had no idea that this outstanding ornamental is found this far north, and this information alone would have made the expedition worthwhile.

We climb to 2,000 feet and enter a dense forest of Loquat Leaf Oaks (Quercus rysophylla). Growing in the deep shade of these giant, old evergreens are thousands of palms (Sabal Mexican) which vary in size from grass-like seedlings to stately specimens up to 30 feet tall. Every once in a while, this lower canopy of dark, blue-green foliage is punctuated by the bright, acid-green leaves of a lone Brahea edulis palm that has made its way down from its usual habitat on the high ridges above.

We slowly creep higher and higher —  sometimes the tires barely make it from boulder to boulder. Often the door panels of the vehicle are only inches from solid stone on both sides. At 2:00 p.m. we have traveled 15.7 miles since crossing the river in the lowlands and have reached an altitude of 3,600 feet. We are traveling on a secondary ridge overlooking a breathtaking view that faces southeast. Through tall oaks, pines, and trunkless palms (yet another species) there are vistas of miles and miles of mountains fading into the distance. On all sides, tall rock formations thrust out of the grassy meadows. These monolithic stones, etched with intricate patterns of yellow, red, and orange lichens, are surrounded by pines with outstretched branches that sweep toward the earth. This combination of forms in a setting of gauze-like layers of mountains and valleys bring to mind recollections of early Chinese watercolors.

Since we had no idea of the time involved in finding our way into these mountains, we failed to bring a tent or sleeping bags. There are only a few hours of daylight remaining to look for the magnolia, but despite this urgency, we know that it is necessary to eat and rest for a few moments. We are famished and exhausted from anxiety and the constant jostling of the vehicle bouncing from rock to rock. So why not stop here in the midst of a beautiful space? And just as important as food for the body, we would afford ourselves a moment to examine and admire the pines (Pinus nubicola) and palms (Brahea moorei).

Shortly after lunch we reach a stretch of road that has been crudely blasted out of the side of the mountain — barely wide and tall enough for the truck to squeeze through. Just inches from the wheels on the driver’s side there is an abrupt drop of a thousand or more feet. The view is dramatic, but there is a sigh of relief from all as the road slowly turns west and widens. Although the sheer stone walls are unnerving, they make an ideal habitat for a showy display of maroon, green, and silver hechtias — some are even combinations of these colors. The older plants have reached three to four feet across and their spiky, heavily serrated leaves swirl outward to form spectacular pinwheels flattened against gray stone.

Around 4:00 p.m., we reach the west side of another saddle between two mountains. The altimeter reads 4,000 feet. Growing between massive plates of smooth, gray limestone, mature oaks (Quercus canbyii) dot the landscape. This tough and uniquely beautiful tree is almost always found on dry and exposed sites. Strong winds sweep these rock surfaces clean, and only the toughest and most adaptable plants survive in areas like this. Agaves and dasylirions compete for soil on the rocky ledge above the road. In the deep crevices we see cactus (Mammillaria rubrograndis), two species of zephyranthes and numerous echeveria, their fleshy, blue-green, pink and mauve leaves pulled tight for protection against winter cold and drought. Huge boulders line the lower side. These are entwined with thick mounds of butterfly vine (Mascagnia macroptera). The lacy, bright yellow flowers have long fallen, but they have been followed by clusters of rusty brown seed pods that resemble butterflies in flight.

The xerophytic make-up of this stark limestone uplift gives no indication that magnolias could be growing anywhere in the vicinity, but suddenly the road makes a sharp turn and we veer east. There is a simultaneous question from all, “liquidambar?” In a distant valley, beneath a high northeast facing ridge, we see scores of trees with vibrant orange, yellow, and scarlet foliage (in Mexico, sweetgums [Liquidambar styracitlua] color up in late autumn and do not defoliate until January and February). The old plant inventory maps group Liquidambar styraciflua and Magnolia grandiflora growing together at the same location. If these distant, colorful trees are indeed liquidambar, there is a glimmer of hope. All are in agreement and confident that these are Mexican sweetgums and there is a feeling of excitement and anticipation.

Within moments we enter a whole new world of flora and fauna. The stone lined road gives way to gentle, rolling earth. Giant pines, oaks, and hickories are the dominant trees. We are flanked by mountains that are 8,000 to 9,000 feet, and the slopes are thick with sweetgums, their fall color intensified by the late afternoon sun and the contrasting evergreens. The towering peaks act as rain magnets during the summer and provide shade and fog during the dry season. This, combined with deep and fertile red clay soil, has produced a forest of incredibly large trees. The dominant oak is Quercus satorii, many reaching a height of over 100 feet. We had seen this exceptionally handsome oak at Rancho del Cielo Biosphere Reserve, and it was growing with magnolias. Everything is beginning to fall into place. But where are the magnolias?

Driving out of the tall trees, we move onto a cleared meadow with grass sod that is kept mowed by grazing animals, and in front of us there is a magnificent view into a deep and heavily forested valley. The other sides of this pasture are lined with dense mounds of Senecio aschenborianus which are covered with large cymes of deep yellow flowers. It is 5:00 p.m. and the open space gives a false sense of remaining light, and the low winter sun on the senecio flowers creates a strange and dramatic setting. The road leads us into another pine-oak forest, and only a few hundred feet ahead we are in the midst of a thicket of young liquidambar trees. The road forks, and the right turn appears to lead to higher elevations and the left turns sharply northeast. Our better judgment tells us that northeast will be cool and damp; fortunately, this time we are correct.

At 4,000 feet, the woods become dense, and under the canopy of foliage the remaining light is dim. We are in the midst of an extraordinary array of life. This gentle north slope creates a perfect setting for deciduous and evergreen quercus, pinus, carpinus, nyssa, carya, and persea. The understory is thick with Taxus globose, vacciniums, and Cornus florida subsp. urbiniana. Gelsemium, mitchella, salvias, aquilegia, zephyranthes, beschorneria, and all sizes of ferns and mosses crowd the forest floor. Only a few feet into this magical space and we turn into a deep arroyo that is moist from seeping water. We know that at long last we are in the right place. “Here they are!” There are magnolia branches everywhere” above us and below. Some trees are thin and stately, reaching toward the sky. Several have been pushed over by rock slides and are growing prostrate along the incline, and others have air layered under the damp and thick mat of decaying leaves that gather between boulders. Trees whose trunks have been buried in broken stones are surviving and sending up new leaders from exposed branches.

There are no flowers, and we are much too late for seed, but we carefully examine the rich green foliage and feel confident that this is not Magnolia grandiflora. But what is it? It must be the same magnolia as those found at Rancho del Cielo Biosphere Reserve, but the leaf structure and color appear to be noticeably different. Even among the ten to twelve trees at this location there are many variations.

We collect five air layered cuttings from fallen trees, making sure that there are two from a tree that has very dark, exceptionally long and narrow green leaves. The one or two delicate white roots are carefully wrapped in damp paper, placed in a plastic bag, and then stored in an empty cooler. We quickly record our mileage (21.45 miles), elevation (4,100 feet), and give the cuttings a collection number (T28M-8p-121790).

It is now dark and only glimpses of light pierce through the dense foliage. At this location there is no space to turn the vehicle around, so it is necessary to continue for another mile before finding a safe place to make this maneuver. In deep darkness and silence, we slowly retrace the day’s journey back to Linares for a few hours of rest before heading out on another adventure. We are exhausted from tension and every bone is reacting to the constant joggling. But all are happy and excited within — we have found our way into a paradise-like setting with overwhelming diversity of flora and fauna and have located the mystery magnolia.

Pictures of Antiquity

Cycads are woody plants that superficially resemble palms and tree ferns. They are found around the world in both hemispheres in tropical and subtropical zones. There are 11 genera of Cycads, some of which are Zamia and Dioon. In the mainland United States we have one species of Cycad – Zamia floridana.

Dioon on hill in Mexico
Dioon on hill in Mexico

It is a native of Florida and extends into southern Georgia and is referred to as Cootie. It is used widely in Florida as a drought tolerant landscape accent. Here at Peckerwood the Florida Coontie was the first Cycad tried; it has proliferated, setting enormous fruit bearing cones with bounties of fertile seed. That led the way for others.

In 1988 John Fairey and I collected seed of Chamal (Dioon edule var. angustifolia) in northeastern Mexico. These germinated and after twelve years are about 16 inches tall and have about eight leaves atop a small swollen stem (caudex). Cycads are extremely slow growing to our eyes but we must understand that they have been around for over 200 million years. Notice their distinctive character which reflects their antiquity.

Photos show them in habitat with close-ups of the flowering or reproductive structures in both sexes. A detail of the fertile cone with maturing seed reiterates their simplicity. The last image is a detail of the rigid leaf, which is retained for some number of years.

Dioons are ancient woody plants and some very large specimens could possibly be several hundred years old. They inhabit steep hillsides where the soils are skeletal and poor. In areas were the decomposed shale is deep they proliferate and create an unreal prehistoric setting, dominating the environment. Chamal can also be found in more hospitable soils and shelter, but there they are small and scattered. Interestingly, Dioon edule specifically has the ability to contract its stem underground as it grows — thus maintaining relativity in the amount of trunk exposed. One suggested explanation for this strange (unplant-like) activity is to reduce its exposure to environmental stress and predation — remember these plants were around during the time of dinosaurs. Also, they may go through prolonged periods of rest, revealed as narrowing in the diameter of the trunk. Some feel that these plants are not regenerating at this time. Are they possibly endangered or just taking a rest that will wait out our short impatient lifetimes? The greatest danger to their existence is ignorance and apathy. They truly are unequalled and intriguing living organisms that count the eons of time while we count the seconds.

Expedition to the Edges

We have made a very long day’s drive from Peckerwood Garden and are in the state of Tamaulipas. It is very early, barely light, when we finish a substantial breakfast, energized by the comforts and hospitality of our country inn, Hacienda Santa Engracia.

We pass through and sometimes stop to visit small villages very different from towns of equivalent size back across the northern border. Without city planners or neighborhood building codes, these communities are much more visually integrated into their surrounding landscape. Building materials are for the most part made of the landscape: adobe, wood, weathered stucco and plaster, thatch of nolina, palm, and dasylirion, with a minimum of glass, smooth metal, or factory-produced bricks.

A few houses have metal roofs, and we realize that as modern materials make an appearance here, building supplies like the nolina thatch will be less desirable, and those plants will become less appreciated and open to abuse. Fence posts, instead of being made from machine finished lumber, are tree branches. A fence builder may use a machete to sharpen these poles to very sharp points for deflecting the rain, and often the points are topped with red paint (Sangre de Christo, “Blood of Christ”).

Building colors in earth hues contrast with deeply pigmented shades that we recognize from wild morning glories or on a flowering shrub we had seen on a mountain. Living in such visual harmony with the natural world is of course often explained by economic constraints; if it is true that wealth and industry and high populations bring careless growth and a commercially determined aesthetic, then sad lessons are to be learned. Spanish moss clinging to the power lines will not be tolerated in most cities, and a hand-painted sign, number, or name on a door may take too much valuable time, when a lit billboard could bring so many more customers. For now, we can only be entranced by the elegant juxtaposition of colors on two adjacent walls, and be moved by the visual surprise of finding hand-carved crosses in the village cemetery.

We drive for many miles seeing little other road traffic, telephone lines, or city limits. Farmers here may be organized into ejidos (farming co-ops) which give a sense of community as well as economic solidarity to widely distanced neighbors. The intense physicality of this space is felt even at 100 kilometers per hour.

The dioon hill, all shale and thorny scrub acacia, rises above cultivated corn fields and a winding path of a country road. We see the fluttering fronds of these great and ancient plants, Dioon edulae var. angustifolia, as we approach, smoothly dark on top, light grey-green on the underside, alive in the breeze. As we drag our heavy cameras up the hills, we see that cattle have also climbed here, grazing on the hill. The dioon are fewer than when we last visited. We fear for the future of this plant, seeing only a few regenerating plants.

We find it impossible to care where this unpaved road might lead, as it crosses back and forth a green and rushing creek, because every few feet we see new color of morning glory or some rare plant demanding a photograph and John’s explanation of its growing habit. We stop to photograph a pale sycamore, Plantanus mexicana, and are hypnotized by eddying green water, the occasional bird call, all else silent.

We have hot showers and city excitement in Monterrey and a visit with the charming and knowledgable Porfirio Sosa Jimenez at his gallery and shop Carapán, where we explore a carefully selected collection of folk art from all of Mexico.

Agave montanaAgave lophanthaWe cross a pass south of Ciudad Victoria and drive through desert areas in the rain shadow, up to a high plateau (5000 feet). Driving demands focus, as there are sheer drops just inches from our vehicle. We must back up when the road is too narrow, as trucks have the right-of-way. Up now to 7000 feet and into fog, we see our first Pinus rutis, Agave montana, Arbutus xalapensis, and a tree Nolina. Our view over the valley is vast, little villages dotting the landscape far below. We have noticed white caleche, sandstone rubble, by the roadside, but higher up we find solid limestone, host to the tenacious Agave lophantha.

Violet mountains seem far away as we make our way across vast landscapes with marching armies of gesturing Yucca filifera. By the time we reach the foothills, the mountain tops come and go in the clouds that nourish and sustain much of the vegetation in the highest places. When we have driven as high as possible, even with four wheel drive, we leave our vehicle and continue on foot.

We climb rocky cliffs, careful not to disturb colonies of ferns, Sedum palmeri, and pinguicula which cling tenuously to the granite walls. An intensely green carpet of high country grasses is dotted with minute violet, red, and yellow wildflowers, and then even higher, where mammoth granite boulders create a home for giant mountain spirits. Hearing bells, we meet horses and cattle in groups of three or four, gentle reminders that we are not the only ones interested in what grows up here, and we fear that this diverse vegetation is on their menu. The palette of the land at this altitude is the darkest green of the pines, the deep blues and violets of cloud-filled skies, and rose and pale gray stone. Raindrops send us down to avoid an approaching storm, and our last color memory of the mountain is the soft white of enveloping clouds and the wet blackness of rain on stone.
