Physalis heterophylla

What to Eat

Edible parts: Fruit

The fruit can be eaten raw or cooked — quite pleasant fresh, though on the small side. It works well in pies, jams, and sauces; when making preserves, add pectin or a pectin-rich fruit to help them set. The fruit can also be dried, ground into a meal, and blended into flour for baking. Each fruit comes naturally protected inside its own papery calyx, which keeps off pests and the weather — but the calyx itself is toxic and must not be eaten.

How to Identify

A small plant that keeps growing from year to year. It grows 50 cm tall. It has a stout rhizome or underground stem. The stems are erect and hairy. The leaves have glandular hairs. The leaves are 6 cm long by 5 cm wide. They are almost heart shaped with a few irregular coarse teeth along the edge. The flowers occur singly. They are yellow and funnel shaped. They are purple at their base. The fruit are yellow when ripe and contain many seeds. The fruit are 3 cm long by 2.5 cm across. They are enclosed in a papery husk.

How to Grow

Succeeds in any well-drained soil in full sun or light shade. A polymorphic species.

Propagation: Sow seed in March or April in a greenhouse, barely covering it. Germination is usually quick and reliable; diurnal temperature fluctuations help. Prick seedlings into individual pots of fairly rich soil once large enough to handle, then plant out after the last expected frost, with cloche protection if needed until established. Divide plants in spring — larger divisions can go straight into their final positions, while smaller ones are better potted up and grown on in light shade in a cold frame until well rooted before planting out in late spring or early summer. For basal cuttings in early summer, take shoots with plenty of underground stem when they reach about 8–10cm above ground, pot individually, and keep in light shade in a cold frame or greenhouse until rooting well before planting out in summer.

Medicinal Uses

The seed is considered useful for treating difficult urination, fever, inflammation, and urinary disorders. A tea made from the leaves is used for headaches and as a wash for burns and scalds. A poultice of the leaves and roots can be applied to wounds, and an infusion of the leaves and roots serves as a wash for scalds, burns, and VD sores. Compounds found in the plant are currently being investigated for antitumor activity.

Other Uses

No other uses are known.
