Aesculus pavia var. flavescens
Aesculus pavia L. var. flavescens (Sarg.) Correll
Texas Yellow Buckeye, Yellow Woolly Buckeye, Pale Buckeye, Plateau Yellow Buckeye
Hippocastanaceae (Horse-Chestnut Family)
USDA Symbol: aepaf
A variety of Aesculus pavia that is found in nature only on the western Edwards Plateau of central Texas, where it replaces A. pavia var. pavia. It shares most of the physical characteristics of its species but has pale to vivid yellow flowers, hairier leaves, and a small stature, usually growing no more than 5 to 15 feet tall.
As befits its environment, it prefers rocky limestone soils and is often found on northern exposures. This variety shares its species tendency to lose its leaves by the end of summer. Where its range overlaps with that of variety pavia, red-and-yellow-flowered hybrids occur.
