Yellow Necklacepod, also known as Silver-Bush and Yellow Sophora, is a multi-stemmed, perennial shrub that grows 8 to 10 feet tall and wide. This plant bears long panicles of yellow flowers popular with butterflies and hummingbirds, followed by strings of bead-like seed pods. Yellow Necklacepod grows best in partial shade and dry, sandy soils, and as a native to coastal regions, it can tolerate saline conditions.
