Cassia grandis
Coral Shower Tree
The Cassia grandis, commonly known as the Coral Shower Tree or Horse Cassia, is a broad-crowned tropical American tree that flowers on bare or near-bare wood. Dense racemes open coral pink and age to salmon and apricot, covering the whole canopy before the new pinnate foliage flushes bronze behind them.
It is the largest and heaviest-flowering of the shower trees commonly planted in the Gulf, and it needs the room to prove it. Specifiers use it as a spring feature in parks, resort grounds and wide boulevards.
