The perennial, deciduous herb has bowl-shaped flowers growing from bulbs. The ornamental plant is popular in Asia, North America and Europe. It has gained favor with gardeners due to its low maintenance needs and showy flowers. The linear green leaves are arranged in whorls around the stems. The plant bears small bulbils along the leaf axis.
The plant has average water needs. It should be watered regularly, avoiding overwatering.
After flowering, cut the withered flower at the top of the stem to arrest seed production. Then wait for the leaves to wither and turn brown before removing them. The green leaves nourish the plant.
A high potassium liquid fertilizer should be applied every 2 weeks from planting until 6 weeks after blooming. Apply a thin layer of compost every spring and follow that up with a 2-inch layer of mulch.
