Bottlebrush Buckeye
by Ann McCulloh - posted 07/19/13


Aesculus parviflora flowers begin to open from the base of the 8- to 12-inch panicle, revealing reddish stamens.

Leaves turn a clear light yellow in October.

Bottlebrush buckeye (Aesculus parviflora) is a shade-tolerant native American shrub with ornamental features all year round. Rather slow-growing at first, it produces classic deep green hand-shaped foliage the first couple of years after planting. The plant becomes quite broad and spreading. It will colonize by suckers in an ideal location. Unique, feathery white blossoms begin to appear in the plant’s third or fourth summer in July. These are followed by sparse, knobby fruits containing shiny brown “buckeyes.” The leaves turn a clear lemon yellow in autumn, really illuminating a shady corner. The evenly spaced silver branches resemble deer antlers in wintertime. Bottlebrush buckeye is not browsed by deer, and is relatively unaffected by pests and diseases.
