This week, we are highlighting another salt-tolerant shrub: The yellow necklacepod (Sophora tomentosa var. truncata). This evergreen shrub is found throughout central and south Florida, and is a member of the Fabaceae, or pea, family.

Yellow necklacepod grows naturally in coastal areas, including dunes, coastal strands, and hammocks, making it both drought- and salt-tolerant. It typically prefers full sun and well-draining soils with the ability to tolerate periods of drought once established. It is intolerant of freezing temperatures.

This plant is quick growing and can grow to about 10 feet tall and about 4 feet to 8 feet wide. Yellow necklacepod leaves are pinnately compound and slightly glabrous (smooth and shiny). It blooms year round and produces showy yellow flowers.

“Following its blooms, necklacepod produces unique seed pods that resemble a beaded necklace, which gives this shrub its name,” said SCCF Native Landscapes & Garden Center Assistant Sophie Carpenter, adding that yellow necklacepod is often confused with the nonnative variety, Sophora tomentosa var. occidentalis.

“The nonnative variety is often sold at big box stores and can be distinguished by the many small hairs that cover the plant. Unfortunately, our native and non-native varieties can hybridize, so be careful to purchase from a reputable nursery,” Carpenter said.

Yellow necklacepod is an excellent addition to wildlife gardens. The bright yellow flowers attract a
variety of pollinator species, including butterflies, bees, and hummingbirds.

*Note: The seeds contain alkaloids, which make them toxic when consumed.

Purchase yellow necklacepod and other native plants at the SCCF Native Landscapes & Garden Center at 1300 Periwinkle Way, Sanibel, FL.
