Other Common Names: Peruvian Ground Cherry, Poha, Poha Berry
Related Species: Clammy Ground Cherry (Physalis heterophylla), Tomatillo (P. ixocarpa), Purple Ground Cherry (P. philadelphica), Strawberry Tomato (P. pruinosa), Ground Cherry, Husk Tomato (P. pubescens), Sticky Ground Cherry (P. viscosa). There is considerable confusion in the literature concerning the various species. Hybrids between them are also known.
Distant Affinity: Tomato (Lycopersicon lycopsersicum), Wonderberry (Solanum X burbankii), Naranjilla (S. quitoense), Garden Huckleberry (S. scabrum) and others.
Origin: The cape gooseberry is native to Brazil but long ago became naturalized in the highlands of Peru and Chile and became identified with the region. It was being grown in England in 1774 and was cultivated by early settlers at the Cape of Good Hope before 1807. Soon after introduction to the Cape the plant was carried to Australia where it quickly spread into the wild. Seeds were taken to Hawaii before 1825 and the plant is naturalized on all the islands at medium and somewhat higher altitudes. Only in fairly recent times has the fruit received any attention in the continental U.S.
Adaptation: The cape gooseberry is an annual in at 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 degrees 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.
DESCRIPTION
Growth Habit: The cape gooseberries is a soft-wooded, perennial, somewhat vining plant usually reaching 2 to 3 ft. in height. Under good conditions it can reach 6 ft. but will need support. The purplish, spreading branches are ribbed and covered with fine hairs.
Foliage: The heart-shaped, nearly opposite leaves are 2-1/2 to 6 inches long. They are slightly velvety when compared with the narrower and smoother leaves of the tomatillo.
Flowers: Bell-shaped, nodding flowers form in the leaf axils. They are yellow in color with dark purple-brown spots in the throat, and cupped by a purplish-green, hairy calyx. Fruit buds are produced after 12 to 13 stem internodes are formed.
Fruit: After the flower falls, the calyx expands, forming a straw-colored husk much larger than the fruit enclosed, which take 70 to 80 days to mature. The fruit is a berry with smooth, waxy, orange-yellow skin and juicy pulp containing numerous very small yellowish seeds. As the fruits ripen, they begin to drop to the ground, but will continue to mature and change from green to the golden-yellow of the mature fruit. The unripe fruit is said to be poisonous to some people. Cape gooseberries are self-pollinated but pollination is enhanced by a gentle shaking of the flowering stems or giving the plants a light spraying with water.
