Comment: Collectors' notes: Eve’s Necklace is a fabulous small tree, 15-20 ft tall. Found growing on limestone soils, from NC Texas south to San Antonio and west through the Edwards Plateau. It can also be multi-trunked and shrub like. Leaves, deciduous, pinnate, lustrous and dark green; rounded crown. Flowers, showy, early spring, rose to pink in wisteria like clusters, which are followed by black fruit pods that resemble a string of beads, hence the common name. This is a great small tree for the deep south. In areas afflicted with crape myrtle bark scale, Eve’s Necklace is a good replacement option. Other attributes: easy to establish, easy to train, pest and disease free, multiple seasonal interests, tolerant of alkalinity and drought. In areas with heavier rains and soil drainage issues, plant on a berm in a better drained soil. Wide variation in flower color provides a great opportunity to select for many color forms. Seed collected off 6-8 trees. Received as Sophora affinis (Styphnolobium affine).
