Hylotelephium verticillatum var. verticillatum ("Mitsubabenkeiso")

Japanese name: ミツバベンケイソウ （三葉弁慶草）
Scientific name: Hylotelephium verticillatum var. verticillatum

[Overview]
An evergreen perennial growing on rocky ground in woodland and on rocks along mountain streams.
It has a rhizome.
The leaves are simple, usually in whorls of 3 to 5, or opposite in small plants; they are elliptic to broadly lanceolate, 3–10 cm long and 1.5–3 cm wide, with sparse low teeth on the margin.
The undersides of the leaves are whitish green.
The petiole is 0.2–1 cm long.
A large spherical compound corymb-like inflorescence at the tip of a flower stalk 20–80 cm long bears densely packed flowers.
The flowers are small, pale green and 5-petaled; the petals are broadly lanceolate, 4 mm long, with pointed tips.
There are 10 stamens, slightly longer than the petals.
The anthers just before dehiscence are pale yellow, rarely dark brown.

[Cultivation]
Propagate by division, stem cuttings, or leaf cuttings.
It prefers a sunny, well-ventilated site with well-drained soil.
For potted plants, water when the soil dries, but it may rot if too wet, so reduce watering during the rainy season and the long autumn rains.
For plants in the ground, rainfall is sufficient.
It is tolerant of dryness.
If fertilizer is applied at planting, no further fertilizing is particularly necessary.
