Marmalade Mussaenda is a tropical clumping shrub with clusters of unusual yellow and orange flowers and medium green leaves. Originally native to the rainforests of south-east Asia, Mussaendas appreciate consistently warm temperatures, high humidity, moist soil, and partial sun, especially afternoon shade. Although they are capable of reaching 10-12 feet in height and width in their native environments, in northern climates, when grown in pots they are more likely to reach about 3-4 feet in height. They are not hardy in Chicago and must be brought indoors when the temperatures fall below 50 degrees Fahrenheit.
