Solanum pseudocapsicum aka Jerusalem Cherry

Solanum pseudocapsicum is an evergreen shrub in the nightshade family. Gardeners know it as Jerusalem cherry or winter cherry. It comes from Bolivia, Brazil, and southern South America. People grow it for its bright fruit, not for food. It now grows beyond its native range on several continents. In some countries, it spreads fast and becomes a weed. Birds spread its seeds into disturbed woods and natural areas.

The plant grows upright and forms a small, bushy shrub. The RHS describes plants about 1 foot [0.3 metres] tall. Its garden size range reaches 1.6 feet [0.5 metres] in height and width. It grows fast and can reach full size within a year. Growers often treat it as an annual for winter fruit. Its green stems are thin, wiry, and much branched. Both stems and leaves may be smooth or have hairs. The dark green leaves have a gloss and grow alternately. Their shape ranges from oval to narrow and pointed. Leaf edges may be smooth, lobed, or wavy.

Small, star-shaped flowers open in summer, alone or in clusters. Most flowers are white, though some have a pale purple tint. Glossy berries follow in fall and last through winter. They may be red, orange, or yellow, with round or oval shapes. Each fruit holds many flat, disc-like seeds. Insects and wind move pollen between flowers outdoors. Indoor plants need hand pollination to set fruit. The fruit gives pots and indoor displays their main seasonal interest.

Grow this shrub in bright light and a sheltered spot. It suits sun or part shade and moist, well-drained loam. The sources favour soil with a neutral pH. The RHS recommends peat-free potting compost with a loam base. It suits patios, containers, greenhouses, and rooms with bright light. Bring outdoor pots inside before frost; the plant cannot survive freezing. The RHS rates it H2; NC State lists USDA zones 8–9. Grow new plants from seed or semi-ripe cuttings.

Aphids, red spider mites, and grey mould can cause problems. Honey fungus occurs rarely, according to the RHS. Too much sun or water can make leaves fall. All parts are poisonous and have no edible use. Solanine can cause gut pain, seizures, breathing problems, and shock. The plant harms people, dogs, cats, and horses. Contact can also cause skin reactions, so wear gloves when handling. Keep it beyond the reach of children and pets.
