Introduced by Allen Coombes (no. 293) from Puebla in 1995, and from later gatherings, this remains a rare tree, but it is established in some specialist collections. At Arboretum de la Bergerette a specimen from Coombes 412 is 6 m tall from planting in 1999, and has not been affected by cold or drought (S. Haddock, pers. comm. 2006). The finest specimen seen in the United Kingdom in the research for New Trees is at Chevithorne Barton, currently c.7 m tall (2008) and growing well, and particularly attractive when seen in September as the second flush of growth was developing. The new leaves are red and hairy, soon losing the hairs and becoming bronze. In contrast, the older leaves are a rather dull dark green. A tree from Coombes 427 at Thenford House has developed a flat-topped, spreading habit.
