Wisteria frutescens (Texas Wisteria)
Texas Wisteria grows in moist woods and along the edges of swamps in East and Southeast Texas. It is less aggressive than the non-native Asian Wisteria. Unlike the non-native counterpart, Texas Wisteria blooms after it has leafed out. It needs sturdy support and is best not to be planted near structures it can damage. It can be trained on arbors, walls, and columns.
Texas Wisteria needs regular pruning to control size and shape and to encourage flowering since it blooms on new wood. It tolerates seasonal flooding but can become chlorotic in alkaline soil. It does not like being transplanted.
Texas Wisteria prefers slightly acidic, loamy soil. It blooms best in full sun and should be planted in a spot that’s sheltered from cold winds, ideally facing south or southwest.
