Cassia is a genus of about 37 species of legume trees and shrubs, mostly mid-sized to tall trees, grown as ornamentals in warm climates. Note that the name is imprecise: some plants sold as cassia belong to other genera such as Senna, and cinnamon-like "cassia" spice comes from Cinnamomum.

About

Cassia is a genus of flowering plants in the legume family, Fabaceae, and the subfamily Caesalpinioideae. Species are known commonly as cassias. The genus includes 37 species and has a pantropical distribution. Species of the genera Senna and Chamaecrista were previously included in Cassia. Cassia now generally includes the largest species of the legume subtribe Cassiinae, usually mid-sized to tall trees.

Cassia is also the English common name of some unrelated species in the genus Cinnamomum of the family Lauraceae.

Where it grows

Cassia species occur in a range of climates. Some can be utilized widely as ornamental plants. They have been used in reforestation projects, and species from desert climates can be used to prevent desertification.

Uses

Because the name Cassia is not precise, it is sometimes difficult to know what is meant by references to plants known as "cassias". Cassia gum, for example, is made from Senna obtusifolia, a species formerly included in genus Cassia.
