It is easy to grow but there are a few requirements to assure success.
Shamrocks are native to South America.
Flowers are lilac in color. A suitable compost for shamrocks consists of 2 parts peat moss to 1 part loam to 1 part sand. Bright indirect light is best, but they will grow in lower light levels. Fertilize weekly while they are growing with a balanced fertilizer. No matter what you do, they will seem at times to be unhealthy and lose their leaves.
