Perennials – Chinese Lantern (Physalis Alkekengi)
This European plant has a long history of garden use, first appearing in texts of the sixth century. Its other common names are bladder cherry, Japanese lantern and winter cherry. It is often grown for its autumn fruits, which are much used by flower arrangers.
Physalis alkekengi has, for most of the year, a fairly uninteresting appearance. From August onwards however, the calyces, which surround the fruit and give the appearance of lanterns, start to take on their stunning red-orange colour and grow up to 2in (5cm) long. Cutting for flower arranging should be done as the colour of the calyces changes but if left on the plant they can become skeletonized.
Physalis can be sown under glass, in early spring, and used as an annual, being discarded after the lanterns are cut. When grown as a perennial, plants will die down after the first frost, and emerge early the following summer. The plant tends to have weak stems and can benefit from a few support stakes.
The Chinese lantern will grow in sun or shade, but the best crop of lanterns is obtained on plants in full sun, where the fruits will have formed early. Restrict the spread of this plant by cutting back any roots, which have spread further than 12 in (30cm) from the main plant. Cut deep into the soil with a sharp spade, then dig up and burn the roots.
Growing Requirements
Soil
This plant really will grow in any soil, but grow Physalis in a free draining soil, rich in organic matter for best results. Although established root systems will survive in the driest of conditions, growth is most rampant in moist soil.
Size
Physalis alkekengi can reach a height of 18in (45cm) with a spread of 2ft (60cm).
Propagation
The easiest method of propagation is to lift and replant a handful of roots in the spring or autumn. Chinese lanterns may also be grown from seed sown in the spring.
