This small holly is still rare in cultivation but it is represented in both North American and European gardens, and with its large fruits deserves to be more widely grown. It seems to have been first introduced by Yucca Do Nursery, Hempstead, Texas, in the early 1990s, from collections made in the San Carlos mountains, Tamaulipas. Material from this source is growing at the University of California Botanical Garden at Berkeley. The few examples known in the United Kingdom seem also to be derived from Yucca Do, including a dense 1.8 m shrub at Westonbirt (S. Andrews, pers. comm. 2007). A plant at Tregrehan is now 3 m tall and flourishing after a slow start (T. Hudson, pers. comm. 2007). It does well at Arboretum Trompenburg, where a specimen obtained from J.C. Raulston in 1994 is now 2 m tall (J. Van Meulder, pers. comm. 2007).
