The plant can be used along a walk or as a border at the edge of a landscape bed. The foliage stays fresh looking provided the plants receive some afternoon shade. They look best when provided with occasional irrigation when the weather gets dry.

Plants are useful in salads. Both flowers and foliage can be eaten and are quite nice. Surprise guests by picking bright flowers from the garden and include them in the salad.
