Golden Shower Tree

Cassia fistula is a fast-growing, deciduous tropical tree prized for long, pendulous clusters of bright yellow flowers. Its foliage may drop briefly around flowering, and its long dark pods can remain on the branches into winter. The [University of Arizona Campus Arboretum](https://apps.cals.arizona.edu/arboretum/taxon.aspx?id=606) provides a detailed profile, and [Kew’s Plants of the World Online](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:484507-1/general-information) recognizes the species and records its native range. ## Landscape use Use golden shower as a specimen, shade, or street tree in a warm climate with room for a broad canopy. The flower display is especially prominent on an open-grown tree. Its seeds are poisonous, and fallen pods may add litter, so choose a planting location with those features in mind. ## Foliage and flowers The tree carries glossy, even-pinnate leaves that may fall for a short period before or during flowering. Showy, fragrant yellow flowers hang in racemes from the branches, typically in late spring or summer, with a smaller second display possible later in the year. Long cylindrical pods turn dark brown as they mature. ## Siting and soil Provide full sun and well-drained soil. It tolerates a range of soil types and moderate dry periods once established, but young trees benefit from regular water while roots develop. Protect from hard freezes. ## Maintenance Prune young trees selectively to develop sound branch structure. Remove dead or crossing branches as needed, and clear fallen pods from walkways. Avoid handling seeds or allowing people or animals to eat them.
