Orostachys japonica (Japanese：爪蓮華、昭和、秀女）also known as rock pine is a species of flowering plant in the family Crassulaceae.[1] Native to East Asia. Its main habitat is on the surface of mountain rocks in Korea, Japan and China.[2][3]
Ecology

Orostachys japonica is a biennial/perennial plant growing to 10 centimetres (3.9 in). It is in flower from September to October. The flowers are hermaphrodite. The rosette leaves shape like a spatula.[3]

Suitable for: light sandy and loamy soils, prefers well-drained soil and can grow in nutritionally poor soil.
Suitable pH: acid, neutral and basic alkaline soils.

Because of its growing shape which resembles a pine tree's cone, and its habit of growing on mountain rocks, it is also called rock pine.[2] It grows well in a sunny or semi-shaded(light woodland) location with a well-drained and moist soil that is low in nutrients. Its flowers bloom from September to October. The flowers are white and each flower has 5 conical petals. The flower lacks a peduncle. Its calyx is divided into 5 parts. When the flowers bloom and produce seeds, it dries out.
