The blue willow pea is a slender, willowy tree with drooping branches. Its scientific name fleta means ‘weeping’ in Latin (4), referring to the downhearted air bestowed by its sagging branches. Each greyish leaf of the blue willow pea is divided into one to three, thread-like leaflets (2) (4), and members of the genus Psoralea all have resinous, dark or transparent dots covering the leaves (5). At certain times of the year, blue to pale mauve flowers are borne on slender stems that, like the branches, hang towards the ground (4).
