Hypericum ×moserianum

Japanese name: ヒペリカム モーゼリアヌム
Scientific name: Hypericum ×moserianum

[Overview]
An evergreen shrub produced by a cross between Seiyo-kinshibai and Kinshibai.
In cold regions it loses its leaves in winter.
It grows 60–90 cm in both height and spread.
The branches are reddish, branch well, and arch, giving the plant a rounded form.
The leaves are simple and opposite, elliptic to oblong, 6–7 cm long, with entire margins.
There is a very short leaf stalk.
The flowers are borne singly at the branch tips or 1–8 in a cyme; they are yellow, 5-petaled, 4.5–6 cm across, open in a shallow cup shape, and have many stamens.
The stamens are about half as long as the petals and divided into 5 bundles surrounding the pistil; the filaments are yellow and the anthers are red.
There are 5 styles.
The sepals are often reddish and have fine notches along the margins.

[Cultivation]
Propagate by cuttings or division.
It prefers a sunny site with soil that is well drained and retains moisture, and dislikes dryness.
Direct summer sun and dryness may cause leaf scorch, so it may also be grown in partial shade.
For potted plants, water thoroughly when the soil surface dries; for plants in the ground, rainfall is sufficient unless summer brings a long spell of sunny weather and the soil becomes severely dry.
In spring and autumn, apply slow-release fertilizer placed on the soil.
If pruning, do it in winter.
There are no particular pests or diseases.
