Cassia: Cassia corymbosa (syn. Senna corymbosa)
Cassia corymbosa, previously classified in the Leguminosae family and now a member of the Ceasalpiniaceae, is native to South America.
This robust but tender plant can reach a height of 3 m (10 ft). Besides the attractive pinnate leaves, C. corymbosa has beautiful golden yellowgrouped in clusters that appear in spring and continue until autumn.
It prefers a sunny, warm, airy position such as a roof terrace for instance. In summer, it needs plenty of food and a lot of water. This means that themust never be allowed to dry out. It requires weekly applications of fertilizer and dead blooms should be removed regularly. Fresh seeds germinate very quickly and the best time for this is late winter or early spring. In winter, it should be placed in a light room at a temperature 10° C (50° F) or in a cool, dark room (2-5° C). However, in the latter conditions, it will lose its leaves. Water sparingly in winter but do not allow the root ball to dry out. But excessive moisture can lead to fungal rot [ask me). Cut back the year’s growth in spring.
