(Aesculus glabra) Small native tree to 30 feet , white flowers in spring. Foliage looks similar to chestnut. Grows well in alkaline soils, sun, or partial shade. Aesculus glabra var. glabra, the Ohio buckeye, is not as well adapted in Texas. Aesculus pavia var. pavia, the red buckeye or scarlet buckeye, reaches heights of 15-25 feet and has red flower spikes in spring. Most buckeyes turn yellow then lose their foliage in the heat of summer. Donít worry Ė thatís normal.
