Cultivation and Propagation: It is an easy plant that usually does not give many problems in cultivation. Needs light shade to filtered sun, but will redden with more light exposure. Regular water in summer, keep dryer in winter, needs good drainage It grows much better outdoors in spring and summer, it is also perfect for the bright windowsill. Grow it in light, fertile, well drained, moderate soils, with a slightly acidic pH (5-6). Avoid any frost.
Maintenance: Removal of old flower stalks; It is a suckering species, and one plant can eventually cover a large area. Divide the crowded clumps periodically. During the winter months, the plants should be grown cool to initiate flower development (about 5-10°C )
Propagation: Suckers, division of older plants.
