Pink Sophora Sophora affinis

Texas sophora is a large deciduous multi-trunked flowering shrub or small tree in the Fabaceae (bean) family native to the south central U.S.A. Typically found in locations containing limestone soil.  In its native setting of along creeks, roadsides, pastures, plains, meadows and woodlands, it can be seen growing vine-like and spindly.    The black fruit pods that appear mid-summer through fall resemble a string of beads, hence the common name necklace tree. 

Plant it in the full sun to partial shade in well-drained soil and this plant will grow 15 to 35 feet high, though most are much shorter, and 10 to 20 feet wide with an upright oval crown  Trees located in full sun tend to be shorter in height than those that receive shade and flowering will be more abundant when planted in full sun.  This plant is very heat and drought tolerant.

The leaves are dark green and leathery. Rose-pink pleasantly fragrant flowers form in clusters in the spring resembling wisteria. Showy black pods that appear in the fall and remain on the tree provide winter interest.  The branches are low on the trunk so trees planted where vehicle or pedestrian access is needed will have to be pruned.  

This small tree is commonly used as an understory tree, as a specimen or the back of a border. It can also be grown as a container plant in cooler locations and relocated indoors during colder months.  Repot when growth has reduced, indicating that the container has become too small for the roots to property spread.   

Insects, Diseases, and Other Plant Problems: No serious insect or disease issues. Soils must drain well or leaves will become chlorotic. The seeds and flowers are poisonous to humans.
