Euphorbia ×martini (Martin's spurge)

Japanese name: ユーフォルビア マルティニ
Scientific name: Euphorbia ×martini

[Overview]
An evergreen perennial or subshrub 60 cm tall.
White milky sap comes out when the stems or leaves are damaged.
The leaves are simple and alternate, narrowly elliptic to lanceolate, and gray-green.
They often turn red in winter.
Flowering branches emerge at the branch tips, each bearing ovate bracts at its end, with a cyathium at their center.
The flowers are enclosed in a yellow-green, urn-shaped involucre and have no petals.

[Cultivation]
Propagate from seed, by division, or by cuttings.
For cuttings, wash the cut end with water immediately or soak it in water to wash off the white milky sap, then let the cut end dry before inserting it.
It prefers a sunny, well-ventilated, well-drained soil.
Take care not to let it become too wet; for potted plants, water thoroughly when the soil dries from spring to autumn, and keep it on the dry side in winter.
For plants in the ground, rainfall is sufficient.
It tolerates dryness well.
In spring and autumn, apply a small amount of slow-release chemical fertilizer.
Pests and diseases include rust, powdery mildew and scale insects.
