One of the best summer-flowering shrubs for shade areas, multiple award-winner Aesculus parviflora (Bottlebrush Buckeye) is prized for its spectacular blooms of erect white flower panicles with red anthers and pinkish filaments. Blooming for weeks from early to mid-summer, the flowers are a real delight to hummingbirds and butterflies. They are held above the nicely contrasting foliage of palmate leaves which open bronze, and mature dark green before turning attractive shades of yellow in fall. The flowers are followed by tan-brown, pear-shaped fruits, 1-2 in. in length (2-5 cm) which are inedible and provide a little ornamental contribution to the plant. Winter hardy, this beautiful suckering, deciduous shrub is native to the rich woodland areas in Alabama, Georgia, and northern Florida.
