How it is grown

Prefers a hot dry position in a wall or rock crevice. Succeeds in a well-drained fertile soil, preferably of an alkaline nature, in full sun. Grows well in maritime areas. Plants are possibly hardy to about -10°c, they are unlikely to succeed in the colder areas of Britain. Self-sows freely, it can be grown in wild informal areas of the garden.

Propagating it: Seed - best sown as soon as it is ripe, older seed rapidly loses viability. Either sow in situ or pot up the seedlings whilst still small because plants produce a long taproot and older plants resent root disturbance.

Best place to grow: Cultivated Beds; East Wall. In.
