Dietes – Plant of the Week

One of the great things about our Plant of the Week is that it is virtually unkillable.

A great choice for lazy gardeners!

Care: Grow in full sun or part shade. Although tolerant of tough conditions, Dietes will perform best in well-drained soil, rich in organic material. Fertilise occasionally and water during dry spells. Do not remove flower stems as they continue to flower for several years. Propagate by seed or by division of established clumps.
Getting started: Dietes iridioides is readily available at nurseries. It costs around $16 for a 200mm (8″) pot.
