Neutral coriaceous On May 18, 2014, coriaceous from ROSLINDALE, MA wrote:

This male cultivar is said to differ from the species in having a more tree-like habit and in having larger, more profuse flowers.

Like the species, this is very late to emerge from dormancy in the spring, generally not till June here (Boston Z6a).

Introduced by Highland Creek Nursery of NC.

It grows beautifully in our slightly alkaline, clay Kansas soil. There is a huge old one at Carroll mansion in Leavenworth, too. It is one of my favorite trees of all. No disease or insect problems. Tolerates our weather extremes. Slow growing is the worst I can say about it.
