Hoptree (a.k.a., wafer ash) is a large shrub with a rounded, irregular crown and (usually) a robust central trunk up to 6" across. Hoptree may produce single-sex (male or female) or bisexual (male and female organs both present) flowers on the same tree. Individual flowers are about 1/4" across, regardless of gender. Perfect (bisexual) flowers have 4-5 greenish sepals, 4-5 narrow, creamy white petals, 4-5 stamens with hairy white bases and yellow anthers, and a single, flattened green pistil. Male flowers are more or less identical but lack the pistil; female flowers are more or less identical but lack the stamens. The fruits are single seeds 1-1.5" long with a broad, flattened, papery wing extending almost all the way around the seed.

About

I want to acknowledge the work of a friend and colleague, Dr. Fred Donner. We both share a passion for the flowers in Jackson Park. Fred's website (jacksonparkwildflowers.org) inspired me to build my own website and database; use and enjoy them both.

I am also pleased to thank my ninja web gurus and coders, Lindsey Young and Stefanie Engstrom. This site would not exist without their herculean labors.
