Ornamental Trees: Extinct and Rediscovered
Ornamental trees are generally grown for their aesthetic appeal, although they may also provide other boons. While most often grown for their flowers or even leaves, some deciduous trees provide a fantastic display in autumn as their leaves change colours.
Several cultivars have been rediscovered in recent years, as their identification often requires specialised knowledge. It is possible that many other 'lost' cultivars await rediscovery, often in public places.

Introduced: pre-1980

Distribution: England (& USA?)
Notes: Discovered as a seedling at Hillier & Son nursery in Ampfield, England. One of the last specimens died at the Sir Harold Hillier Gardens, Hampshire, England. May have been exported to the USA, and hence may still survive there.
