What to Eat

Edible parts: Leaves

Young leaves can be eaten cooked. Some caution is advised regarding toxicity.

Known Hazards

Although no mention has been seen for this species, the leaves of at least two other members of the genus contain saponins. Although toxic, saponins are very poorly absorbed by the body and so tend to pass through without causing harm, they are also destroyed by thorough cooking. Saponins are found in many plants, including several that are often used for food, such as certain beans. It is advisable not to eat large quantities of food that contain saponins. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish.

Where to Find It

It is a temperate plant. It grows in wet valleys and swamps in north China between 200-600 m above sea level.

How to Identify

A herb. It grows 12-15 cm tall. It has a taproot. The stem is erect and un-branched. There are several leaves at the base. The leaf stalks are 5-1 5 cm long. The leaves are heart shaped or kidney shaped and 2-4 cm long by 4-7 cm wide. They have 3 parts. There are irregular teeth towards the ends. There are about 20 male flowers in a group and 3 female flowers.

How to Grow

We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in most parts of the country. The following notes are based on the general needs of the genus. Succeeds in any moderately fertile well-drained soil in sun or semi-shade. Strongly dislikes poor thin soils. Prefers a loamy or calcareous soil.

Propagation: No specific information is available for this species; the following notes apply to the related S. europaea. Stratification improves germination. Sow seed in autumn if possible; sow stored seed as early in the year as possible. The best results come from sowing in situ in woodland soil under trees. If seed is limited, sow in pots of woodland soil in a shady cold frame. Once seedlings are large enough to handle, prick out into individual pots and grow on in a shaded greenhouse position through their first winter, then plant out in late spring or early summer after the last frosts. Divide in spring — larger divisions can go straight into permanent positions, while smaller ones do best potted up and grown on in a lightly shaded cold frame until well established before planting out in summer.
