Portulaca grandiflora is a half-hardy annual, that is drought tolerant which makes it well suited for borders, rock gardens, hanging baskets and containers,or as ground cover plants.

They are well suited to poorer quality soil and dry conditions providing they have a sunny aspect as indicated in its common name.

The plants grow about 100-200 mm (4"-8") high, and spread to around 500mm (18")

The saucer-shaped Yellow, orange, red, pink, white,or bicoloured flowers appear from June to September.
