'Firefall'TM freeman maple.

摘要

Firefall, a new cultivar of the popular landscape tree freeman maple (Acer freemanii), was derived from crossing silver maple cv. Beebe and red maple cv. Autumn Spire in Minnesota, USA in 1990. Officially released to wholesale nurseries in 2001, Firefall is selected for its cold hardiness, symmetrical form, seedlessness, and consistently early and attractive autumn colour display.
