How to Grow Sparaxis

Sharing is caring!

Sparaxis is grown for its showy, brightly colored, funnel-shaped flowers carried in loose spikes in spring and summer. Flowers come in yellow, pink, purple, red, and white usually blotched and splashed with contrasting colors.

Sparaxis is sometimes called harlequin flower or wandlfower. Individual flowers have six petal-like tepals that are joined at the base to form a short tube. Each corm bears two or more stems each with 2 to 10 flowers.

Sparaxis grows from small corms. Plants produce lance- or sickle-shaped leaves, usually arranged in fans.

Sparaxis is suited for well-drained soil. Where winters are wet or cold, grow Sparaxis in pots that can be moved indoors in winter.
