Cassia javanica

Cassia javanica

Rainbow Shower Tree

Cassia x nealiae is a hybrid between C. javanica x C. fistula. This is not a single variety. Different clones have different flower colours and there are at least four named cultivars in Hawaii. (See the University of Hawaii at Manoa publication ctahr.hawaii.edu/oc/freepubs/pdf/OF-42.pdf). The lack of seed pods from these sterile hybrids is an advantage in many landscape applications. Unfortunately, these hybrids are not easy to find for sale in Australia although there is at least one type that is occasionally available.
