Bottlebrush buckeye is a handsome shrub that has memorable long fluffy white flower clusters in early July. It is useful as an understory planting in woodland gardens, as a specimen plant, or in a shrub border. The wonderful, coarse-textured, dark green compound leaves turn rich buttery yellow in the fall. This is a large shrub that tends to sucker and, over time, will grow twice as broad as it is high, so it should only be used in large-scale plantings. Also known as Aesculus macrostachya.
