Eucalyptus cinerea (Argyle apple)

Japanese name: ギンマルバユーカリ
Scientific name: Eucalyptus cinerea

[Overview]
An evergreen tree reaching 15–30 m in its native habitat.
The bark of young branches peels off, but on the trunk and main branches it becomes fibrous.
Young branches and leaves are powdery white, giving the whole plant a silvery appearance.
The juvenile and adult leaves differ in shape; juvenile leaves are simple and opposite, round to heart-shaped, about 3–5 cm in both length and width, and have no petiole.
Juvenile leaves often remain even on mature trees.
Adult leaves are simple and alternate, lanceolate, 9–14 cm long and 1.5–5 cm wide, and have a petiole.
In the flower, the petals and calyx are fused into a cap, which falls off when the flower opens.
The flower has no petals and has many white stamens.
The fruit is a spinning-top-shaped capsule.

[Cultivation]
Propagate from seed.
It prefers a sunny, well-drained, fertile soil.
Transplanting mature trees is difficult.
It is best kept slightly on the dry side; for potted plants, water thoroughly when the soil surface dries, and for plants in the ground, rainfall is sufficient.
If basal fertilizer is applied, no further fertilizing is particularly needed.
Powdery mildew can occur.
