Gardening: Almost all the species and cultivars produce flowers very freely in summer and rains. They prefer full sun, porous soil rich in humus. Light pruning is necessary to maintain the shape and promote new shoots for flowering next year. Varieties of I. coccinea, I. lutea and I. chinensis respond to hard pruning. As a result of hybridization and natural crossing, many cultivars have developed some of which are of horticultural importance. Many such hybrids exist in the garden of the Agri – Horticultural Society of India, in Calcutta.
