These vigorous perennials have linear leaves up to 24 inches long with spikes of up to 20 funnel-shaped, marked, deep magenta flowers which appear in spring. In the Mediterranean it is a wild flower in the olive groves through May and June and is naturalised in the South-West of England in Cornwall and the Scilly Isles where it is called Whistling Jack! It thrives in full sun and fertile, well-drained soil.
Sow seeds at any time, covering them very thinly with compost or grit, keeping the seed pot in a cool, well-lit spot outdoors. Artificial heat is not needed and can prevent germination so be very patient as many species will only germinate in the spring after chilling or freezing in the moist seed pot in the winter. Grow on individual seedlings in small pots until of sufficient size to be potted on or planted out into the open ground.
