This evergreen shrub reaches a height of about one meter. It can be grown in temperate climates as it is somewhat frost-hardy.
In the Northern Hemisphere, it flowers in July.[1] The flowers fold in the shade and at night. The flowers are yellow, with 5 sepals and sub-equal petals, 10 very unequal etamins in 3 groups [3-4-3] and a style very curved upwards. It blooms in summer and autumn and is visited by bumblebees, which are responsible for its pollination. The fruit is a hanging indehiscent legume, cylindrical in shape (about 6 to 10 cm) full of seeds.
