Psoralea pinnata is a fast growing, evergreen bright, shrub with beautiful foliage similar to that of the tamarisk. The leaves look needle-like, are dark green and scented which can be smelt when crushed. During Summer it bears masses of light-blue, pea-shaped flowers, some plants have dark blue, purplish or even white flowers. Flowering can sometimes last all the way through to Autumn.
Psoralea pinnata is ideally suited for a screen as the foliage is quite dense, it is a really fast grower, is very neat and can reach a size of 3x2m in a garden. It prefers a warmer climate with higher rainfall or moderate watering and it is not suited to droughts.
