Its blossoms are produced in June and July, the buds are covered with a white down, as is also the underside of the leaves, whence its name of tomentosa.
It has been customary to treat it as a stove plant, such it is considered in the Hort. Kew. there is great reason however to believe, that it is by no means tender, and that it may succeed as most of the Chinese plants do in a good greenhouse.
It is usually increased by cuttings which are struck difficulty.
