Succeeds in most soils if they are well drained, doing well on chalk. Plants are very tolerant of maritime exposure but will require staking at first if planted in an exposed area unless planted out whilst still very small. Prefers a sunny position but tolerates light shade. This species is not very hardy in Britain, it succeeds when grown against a wall at Kew and grows very well in S.W. England. Established plants can tolerate temperatures down to about -15°c if the soil is well drained. A very ornamental plant, the flowers are very attractive to wasps. Plants are very tolerant of trimming and can be pruned right down to the ground if required. When bruised, the leaves release a pungent smell.
