Dunce's Caps Overview

Orostachys spinosa is a perennial, succulent species in the stonecrop family, Crassulaceae. It is monocarpic in nature, flowering once then dying, but readily produces offsets around the main plant. These can be easily seperated to create more plants! This genus originates from rocky, mountainous regions in Russia, China, North & South Korea and Japan. Foliage is arranged in tight, spherical to hemispherical rosettes measuring up to 10cm in width. Leaves are thick and fleshy, with spines on the tips and these range in colour from green-grey to red-tinged under strong sunlight. Flowers are short-stemmed and arranged densely on spike-like inflorescences up to 30cm in height. They are starry in appearance, coloured cream and produced in the summer-autumn.
