yellow necklacepod, Sophora tomentosa

It's terrible cold here, so let's go south. This necklacepod is pantropical. It's an endangered species in Australia. In Africa and Asia it is used as fish poison and insect repellent. Here it is native to coastal areas of FL and TX, where it is also a good garden shrub and nectar source. Polk Co FL, 3/17/16.
