Groundcherry (Physalis)
Description
Physalis from physalis = bladder is a genus of flowering plants in the nightshade family (Solanaceae), which grow in warm temperate and subtropical regions of the world. Most of the species, of which there may be 75-90, are indigenous to the New World. Cultivated species and weedy annuals have been introduced worldwide. A notable feature is the formation of a large papery husk derived from the calyx, which partly or fully encloses the fruit.The fruit is small and orange, similar in size, shape and structure to a small tomato. At least 46 species are endemic to the country of Mexico.Many Physalis species are called groundcherries.One name for Physalis peruviana is Inca berry; another is Cape gooseberry, not to be confused with the true gooseberries, which are of the genus Ribes in the family Grossulariaceae. Other names used to refer to the fruit are poha berries, and simply golden berries. Physalis are herbaceous plants growing to 0.4 to 3 m tall, similar to the common tomato, a plant of the same family, but usually with a stiffer, more upright stem. They can be either annual or perennial. Most require full sun and fairly warm to hot temperatures. Some species are sensitive to frost, but others, such as the Chinese lantern, P. alkekengi, tolerate severe cold when dormant in winter.
