Physalis pruinosa is a plant in the genus Physalis in the nightshade family Solanaceae, often referred to as ground cherry or husk tomato. It is a native species in a range extending from northern Mexico through Central America. [1] The plant has a low, spreading habit, and fruits develop in a papery husk, as is characteristic of the genus.
Physalis heterophylla is a perennial, and is one of the taller-growing North American members of the genus, reaching a height up to 50 cm. The leaves are alternate, with petioles up to 1.5 cm, ovate in shape, usually cordate at the base (this is especially true of mature leaves), 6–11 cm long at maturity.
Physalis plants grow in most soil types and do very well in poor soils and in pots. They require moisture until fruiting. Plants are susceptible to many of the common tomato diseases and pests, and other pests such as aphids, whiteflies, spider mites, and the false potato beetle (Leptinotarsa juncta) also attack them. Propagation is by seed.
Physalis longifolia, known by the common names common groundcherry, longleaf groundcherry, [1] and wild tomatillo, [2] is a species of flowering plant in the nightshade family, Solanaceae. It is native to North America, where it is native to eastern Canada, much of the continental United States, [ 1 ] and northern Mexico.
The plant is readily grown from seeds, which are abundant (100 to 300 in each fruit), but with low germination rates, requiring thousands of seeds to sow a hectare. [2] Plants grown from year-old stem cuttings will flower early and yield well, but are less vigorous than those grown from seed.
The overall purpose of this study was to identify the chemical compounds of P. virginiana that could be used to make antibiotics. The researchers introduced extracts from the plant to twelve different bacteria cultures. They found that extracts from the plant inhibited the growth of eight out of the twelve strains of bacteria.
Prunus ilicifolia flowers. It is an evergreen shrub [4] or small tree approaching 15 metres (49 feet) in height, [12] with dense, hard leaves [4] (sclerophyllous foliage). The leaves are 1.6–12 centimetres (3 ⁄ 4 – 4 + 3 ⁄ 4 inches) long with a 4–25 millimetres (1 ⁄ 8 –1 in) petiole [12] and spiny margins, somewhat resembling those of the holly.
Physalis angulata is an erect herbaceous annual plant belonging to the nightshade family Solanaceae. Its leaves are dark green and roughly oval, often with tooth shapes around the edge. The flowers are five-sided and pale yellow; the yellow-orange fruits are borne inside a balloon-like calyx. The exact native range is uncertain.
