Daphne tangutica's mature height is about 2 and a half to three feet max - prefers light shade, well drained soil, but doesn't like to dry out, so if in a pot, water when the compost is just starting to dry, and don't leave it standing in a drip tray of water for longer than half an hour. Topdress with Growmore in Spring, raked in around the roots, but gently - they don't like root disturbance and hate being moved, so pick your spot carefully if putting in the ground.
