The whole plant is poisonous[
E. Asia - Siberia to N. China.
Sparse forests ad bushes at the road[
Succeeds in any moderately fertile soil that does not dry out excessively in summer, in sun or partial shade[
]. Prefers full sun[
This species is hardy to about -30°c, but, due to a lack of summer heat, the plants usually produce soft growth in mild maritime areas and this can be cut to the ground at temperatures around -5 to -10°c[
The plants do not require pruning, but can benefit from being cut back to ground level every 2 - 3 years in order to keep them tidy[
Closely related to M. canadense, differing mainly in its annual or rarely persistent aerial stems[
A twining plant, it spreads freely by means of underground suckers[
A dioecious species - both male and female forms must be grown if fruit and seed are required.

Mint species are usually good bee and butterfly attractant plants, supplying them with good quality pollen and nectar[
Mints are usually quite aromatic plants and they make good companions for cabbages and tomatoes, their aromatic nature helping to repel insect pests..
Seed - sow late winter in a greenhouse[
]. Two months cold stratification speeds up germination[
] so it might be better to sow the seed as soon as it is ripe in a cold frame[
]. Germination is usually good[
]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
Cuttings of mature wood, autumn in a frame[
Division of suckers in early spring[
]. The suckers can be planted out direct into their permanent positions, though we prefer to pot them up and grow them on in light shade in a greenhouse or cold frame until they are established[
