The cape gooseberry is an annual in temperate regions and a perennial in the tropics. In the Andean regions of South America it grows wild between 2,500 and 10,000 ft. The wild range in Hawaii is 1,000 to 8,000 ft. The plants are frost tender and are killed at temperatures of about 30° F. In much of California the cape gooseberry is best grown as an annual, but will persist for several years in frost-free areas of southern California. Some California growers have grown seedling materials under glass during the fall and winter and set out in early spring to gain the advantage of the longest possible growing season.The plants are easily grown in pots and adapt well to greenhouse culture.
