Cassia javanica is planted primarily as a decorative shade tree. Many people consider pink and white shower to be aesthetically pleasing because of its pink and white blooms that emerge during the summer months. Because its leafless season is so short, it can be a good shade tree throughout the year. Its rapid growth rate makes it an ideal tree for homeowners looking to increase their tree cover. And its natural resistance to pests increases its desirability as a landscape tree that is commonly used as an ornamental street tree. This 2-page fact sheet was written by Michael G.
