Previously thought to be a form of Quercus sartorii, the identity of this oak species is inconclusive, and could very well be a new, undescribed species. We are sticking with the designation that Yucca Do Nursery offered it as in recent years, which refers to the San Carlos Mountains in northeastern Tamaulipas where John Fairey and Carl Schoenfeld collected it. The unique shape of the narrow, jaggedly toothed leaves that emerge a hot pink color make this a favorite oak among many enthusiasts. We have a few well-started seedlings available that were kindly donated by Wally Wilkins, propagated from acorns collected in the garden.
