How to Grow Schizostylis Plants

Guide to Growing Crimson flag lily

Schizostylis plants are hardy perennials that reach about 60 cm in height.

They bloom from the end of summer through autumn with cup shaped flowers of red or pink; these are are carried on spikes.

Although they are still commonly known as Kaffir Lily in many parts of the world this name is rightfully becoming less used. This is because the word Kaffir is used as a derogatory term for black people in South Africa. We recommend that you refer to the plant as the Crimson Flag Lily when you discuss it to help encourage the use of this friendlier plant name.

How to Grow Crimson Flag Lily and other Schizostylis

Schizostylis plants can be grown from tubers or seeds. Tubers should be buried at about 5 cm deep in the spring. Seed should be sown before the last frost of spring, and lightly covered with topspoil. They can grow in either sunny or partially shaded conditions and requires an area of the garden that has good drainage. Ideally the soil that the lily grows in will be rich, moist and have a PH that is neutral to slightly acidic.

If you plan to start off indoors then start about two or three months in advance (they need to be transplanted just after the last frost of spring). It should take from one to three months for seeds to germinate at a temperature of 12 to 15 degrees centigrade. Once ready transplant outdoors at about 25 to 30 cm apart.

Caring for Crimson Flag Lily

Crimson flag lily and other Schizostylis take a little looking after. It is best to grow them in an area that does not receive much wind. If growing from tuber, then supply a mulch in the first winter to protect the plant from cold. In all cases supply a mulch in spring to help keep the soil cool; the lilies should also be fed in the spring, and a further two times whilst growing. Schizostylis plants likes to grow in a moist soil so keep well watered in dry spells. To maintain vigorous growth divide the plant every three years. If you require more plants then propagate by division in the spring ensuring to leave five eyes.
