Seed - surface sow March in a greenhouse. The seed usually germinates in 10 - 21 days at 18°c[4]. Cool nights assist germination[4]. When large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. The seed can also be sown in situ in July/August and will produce larger and more floriferous plants the following summer. Cuttings of half-ripe wood in September in a cold frame[7].

Prefers a light well drained loam and a sunny position[1][7]. Plants are tolerant of clay and lime soils, and also grow well on old walls[7]. Plants are often grown as an annual since they usually degenerate in their second year[1]. They often self sow when well-sited[K]. There are many named forms, selected for their ornamental value[7].
