Raoulia hookerii

Vegetable sheep. Ground hugging plant, which grows into a tight spreading woolly silvery white mat with small yellow flowers. Stems are much branched, and root into the ground. Occur naturally on scree and moaine where they form rudimentry humus soil as they die and rot, providing a mossy seed bed for other species. Excellent for scree gardens and rockeries, provided they are not shaded out by larger plants, and are kept moist.
