Cape gooseberry, closely related to ground cherry, is a remarkable and productive plant grown for its delicious orange fruits wrapped in decorative papery husks. Reaching up to 2m in height, these heat-loving plants perform best in a greenhouse or the warmest corners of the garden. The fruit has a sweet, slightly tart flavour and is excellent eaten fresh, cooked in desserts, or made into jam. It also stores surprisingly well for several months when kept in its husk.

Where can Cape gooseberries be grown?

These plants prefer full sun and heat, thriving in zones 4 to 9 with extra protection like a greenhouse or a warm microclimate. They are suitable for greenhouse beds, large containers, or sheltered outdoor spaces with good heat exposure.
