Edible parts: Leaves, Root

North American Indians boiled the roots for a long time before eating them. Even after thorough cooking, eating the roots was considered to cause drowsiness, and consuming too many was said to cause nausea.

Known Hazards

Roots may cause drowsiness and nausea if consumed in large quantities.

How to Identify

A low fleshy herb. It lies along the ground. It keeps growing from year to year and roots at some of the nodes. The leaves are narrowly oval and mostly opposite. The leaves do not have stalks and do not have teeth. The flowers are pale pink, purplish or white. They are 3-6 mm across. They do not have petals. They occur singly at the base of the leaves. The fruit is a 5 valved capsule.

How to Grow

Succeeds in most soils. Dislikes shade.

Propagation: Sow seed in spring in a cold frame. Prick seedlings into individual pots when large enough to handle and plant out during summer. Where seed is plentiful, a direct outdoor sowing in situ in mid-spring is worth trying. Divide clumps in spring — larger divisions can be planted directly into permanent positions, while smaller clumps are best potted up and grown on in a cold frame until well rooted, then planted out in spring.

Medicinal Uses

Some Native North American peoples ate the boiled roots to induce sleep.

Other Uses

None known.
