Japanese name: セイヨウカキドオシ（西洋垣通） Scientific name:Glechoma hederacea subsp. hederacea
[Overview]
A perennial 10–17 cm tall.
Crushing the stems or leaves gives off a fragrance.
The base of the stem creeps along the ground and roots at the nodes, and at flowering time the tip rises obliquely.
The base of the stem is tinged with purple and nearly hairless, with stiff hairs at the nodes.
Leaves are simple and opposite, round and kidney-shaped, 0.8–1.3 cm long and about 2 cm wide, with a petiole.
The leaves have few hairs and the margin has blunt, rounded teeth.
Flowers are borne 1–3 at a time in the leaf axils.
The flowers are lipped, 1–1.5 cm long, pale reddish purple, with reddish purple spots on the lower lip.
The fruit is a schizocarp.
[Uses]
The whole plant is used medicinally.
[Cultivation]
Propagate by division and stem cuttings.
It is easy to grow, but care is needed because when planted in the ground it can spread too much and become a weed.
It grows in sun to partial shade and prefers fertile, moderately moist soil.
The plant weakens if it dries out.
In old plants the center may die back, so it is better to renew them by division once every few years.
For potted plants, water thoroughly when the soil surface dries.
For plants in the ground, rainfall is sufficient.
Fertilizing is not particularly necessary.
There are no particular pests or diseases.
