Eve's Necklace Sophora affinis

Previously known as:

  • Styphnolobium affine
Description

Texas Sophora is a large flowering shrub or small tree native to the south central U.S.A.  The leaves are dark green and leathery and it has rose-pink showy flowers that form clusters resembling wisteria.  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 use it as an understory tree.

Insects, Diseases, and Other Plant Problems:  Soils must drain well or leaves will become chlorotic.
