Jerusalem cherry plants (Solanum pseudocapsicum) are also referred to as “Christmas Cherry” or “Winter Cherry.” The Jerusalem cherry houseplant appears as an erect, bushy evergreen shrub. It can be obtained from the local nursery most any time of year and is listed as a winter-fruiting annual. Jerusalem cherry plants have dark green, shiny leaves which are elliptical and about 3 inches long.

Jerusalem Cherry Facts

The Jerusalem cherry houseplant bears white flowers looking much like those of tomatoes or peppers. In fact, the plant is a member of the Nightshade family (Solonaceae) amongst which not only tomato and pepper are members, but also potato, eggplant and tobacco.

The flowers precede long lasting ovoid fruits of red, yellow and orange, which are ½ to ¾ inches long. The brightly colored fruit are indeed the reason for Jerusalem cherry’s popularity and is sold as a houseplant during the dreary winter months when a “pop” of color is just what one needs.

Despite their cheery colors, the fruit of the Jerusalem cherry houseplant is toxic and should be kept out of the reach of curious children and pets. Any part of the plant that is ingested can cause poisoning and even death.

Jerusalem Cherry Care

When growing Jerusalem cherries, the plants may be grown outdoors just as you would a tomato, but should be brought inside before the danger of frost – 41 degrees F. is the lowest temperature the plant will tolerate. Jerusalem cherry care is possible as a hardy perennial in USDA zones 8 and 9.

Either purchase the plant from a nursery or propagate via seed or shoot cuttings. Sow the seed in March after frost and you should have a mature fruiting Jerusalem cherry houseplant by late October.

Growing Jerusalem cherries should be planted in a rich well draining soil. Water Jerusalem cherry plants as needed and fertilize regularly. Feed your plant a liquid fertilizer (5-10-5) every two weeks as the plant is growing.

As a houseplant, situate Jerusalem cherry plants in full sun, if possible, although they will tolerate moderate light. These plants are known to drop their foliage and flowers if they get too warm (above 72 degrees F.), so watch those temps and mist the foliage often.

To ensure fruit set if you are growing the plant indoors (no pollinators, such as bees!), shake the plant gently while in flower to distribute the pollen. Once the fruit is well set, reduce the fertilization schedule and take care not to over-water.

In the spring once the fruit have dropped off, cut this ornamental perennial back to stimulate vigorous growth. If you live in a frost free area and have been growing your Jerusalem cherry as a houseplant, prune the plant drastically after fruiting and then plant it outside in a sunny spot in your garden. Chances are good, that your Jerusalem cherry plant will grow into a 2-3 foot ornamental shrub.

In areas of frost, you will need to dig the plant up every year, repot and grow indoors until it warms outside and it can be moved again.
