Bottlebrush Buckeye, Aesculus parviflora, is a native shrub noted for being one of the best summer-flowering shrubs for shade areas. Growing easily in average, moist loams, its intolerant of dry soils, particularly when young and before root system is established. A dense, mounded, suckering, deciduous, multi-stemmed shrub, it has palmate green leaves (5-7 leaflets) and brilliantly erect, showy, cylindrical panicles (12″ long) of tubular white flowers that resemble a bottlebrush. An absolute butterfly and pollinator magnate.
