One of the finest spring bloomers is the Chinese fringetree, Chionanthus retusus, a large form considered by many to be one of the most beautiful ornamental flowering trees. Produced in loose, terminal 4-inch long panicles, the snow white, fragrant flowers appear just as the dogwoods are finishing their own spring show, and persist for 2-3 weeks. [2]

Grows naturally as a multi-stemmed tree, but can be trained as a single-trunked specimen  to 25 feet in height and even larger spread.  Female plants develop small purple fruit which are highly prized by birds and other wildlife. 

Fringe trees are notoriously slow growing, seldom making more than 10 inches a year, but can be accelerated somewhat if grown in soil rich in organic nutrients and watered regularly. Blooms best in full sun, but can also benefit from several hours of shade every day. [2]
