Aesculus parviflora. commonly called bottlebrush buckeye, is noted for being one of the best summer-flowering shrubs for shade areas. It is a dense, mounded, suckering, deciduous, multi-stemmed shrub which typically grows 6-12' tall. Features palmate green leaves (5-7 leaflets) and erect, showy, cylindrical panicles (to 12" long) of tubular white flowers with conspicuous red anthers and pinkish filaments. Mid-summer bloom can be spectacular. Flowers give way to glossy inedible, pear-shaped nuts (buckeyes) encased in husks, however these nuts are infrequently produced in cultivation in the northern parts of this shrub's growing range (including St. Louis). Foliage turns yellow in autumn.
