Summary
Styphnolobium affine, commonly known as Eve’s Necklacepod, is a deciduous small tree or large shrub native to the limestone soils of open woodlands, forest edges, and riparian areas in the South-Central United States, particularly Texas. It typically grows to a height and width of 25-30 feet (8-9 meters), with a rounded canopy and graceful, arching branches. The compound leaves are dark green and provide dappled shade. In the spring, it produces showy, wisteria-like clusters of fragrant flowers that are pink, purple, and white, followed by distinctive, beaded seed pods that resemble a necklace, hence its common name.
Eve’s Necklacepod is valued for its ornamental flowers, attractive seed pods, and adaptability to various soil types, including alkaline soils. It is drought-tolerant once established, making it suitable for xeriscaping and low-water-use gardens. This species is often used in urban landscapes, as a specimen tree, or for naturalized plantings. It thrives in full sun to part shade and prefers well-drained soils. While generally low-maintenance, it can be susceptible to pests like mimosa webworm and fungal diseases in humid climates. Gardeners should be aware that all parts of the plant are toxic if ingested.CC BY-SA 4.0
