Senna corymbosa is an ornamental plant in the genus Senna. It is also known as Argentine senna, Argentina senna, buttercup bush, flowering senna, Texas flowery senna or tree senna.

Description

Cloudless Sulfur Caterpillar (Phoebis sennae) eating yellow buttercup bush flowers (Senna corymbosa)

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. 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 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.
