Grevillea banksii (red silky oak)

Japanese name: グレヴィレア バンクシー
Scientific name: Grevillea banksii

Grevillea banksii

[Overview]
An evergreen shrub or tree growing 3–9 m tall.
It branches well.
The leaves are alternate and pinnately divided into 3–11 lobes.
The lobes are linear to lanceolate, 5–10 cm long and about 1 cm wide.
Racemes about 15 cm long are produced.
The flowers are red or cream-colored and have no petals; the tip of the tubular perianth opens and the style projects far out.
The fruit is a follicle.

[Cultivation]
Propagate by cuttings.
It can overwinter outdoors in areas without frost, but if it is kept at 10°C or above in winter it can keep growing without resting, so bring potted plants into a sunny place indoors in winter.
It prefers a sunny place with well-drained soil.
Avoid places exposed to cold winter winds.
For potted plants, and for plants in the ground less than 2 years after planting, water thoroughly when the soil surface dries from spring to autumn, and water sparingly in winter.
For established plants in the ground, rainfall is sufficient.
Apply organic fertilizer around the plant as fertilizer in winter.
There are no particular pests or diseases.
