Cassia nodosa, commonly known as Java cassia or pink shower, is a fast-growing deciduous tree native to the rainforests of Southeast Asia. It is often found in secondary forests and forest edges, where it thrives in the warm, humid conditions. Java cassia can reach heights of 82 to 131 feet (25 to 40 meters) with a spreading canopy that provides significant shade. The tree has paripinnate leaves, each with 12 pairs of elliptical leaflets, creating a feathery appearance. The flowering season occurs in spring, when the tree produces abundant clusters of pale pink to crimson flowers with prominent yellow stamens, which are highly ornamental and attract pollinators.

Java cassia is valued for its striking floral display and its ability to grow quickly, making it a popular choice for tropical and subtropical landscapes. It is used as a shade tree in gardens and public parks and is also planted along streets for its ornamental qualities. In cultivation, it requires well-drained soils, moderate to high water availability, and full sun to partial shade. While it is relatively easy to maintain, it can be susceptible to pests and diseases common to the Cassia genus. Java cassia also has various medicinal uses, including the treatment of skin diseases and as a laxative, although these uses require proper knowledge and caution.CC BY-SA 4.0
