Cultivation details
An easily grown plant, fast to establish and flower from seed and growing best in coastal areas[260]. In hot summer climates it requires partial shade, plus ample humidity and moisture in the growing season[260]. Requires a sunny position or part day shade in a fertile well-drained soil[200]. Dislikes drought[200]. Plants do not like windy conditions[260].
This species is only hardy in the mildest areas of Britain, tolerating temperatures down to between -5 to -10°c when given the protection of a south or south-west facing wall[11, 184, 200]. Plants are often deciduous in cold winters[219]. A deep mulch in winter and tying in growth to the wall will maximise protection in winter[200]. If the plant is cut back by cold weather, it will normally resprout from the base in the spring and can flower on the current year's growth[202]. A plant of the cultivar 'Album', growing in an open position at Westonbirt Arboretum, was 2 metres tall and flowering prolifically in June 1994[K].
Plants tend to be short-lived in Britain, dying suddenly without any apparent cause. This is probably because they flower so profusely that they die of exhaustion[11]. They produce an abundance of fertile seed, however, and this normally breeds true to type, whether from the white or the purple-flowered form[11]. Dead-heading plants to prevent seeding can enhance longevity[200].
Tip-prune young plants to promote a bushy habit, older plants can be cut back hard annually in spring if required[200].
There are some named forms, selected for their ornamental value[200]. 'Album' has very nice tasting flowers[K].
Plants in this genus are notably resistant to honey fungus[200].
Propagation
Seed - sow spring in a greenhouse[200]. Germination should take place within a few weeks. Once the seedlings are large enough to handle, prick them out into individual pots. Grow them on for at least the first winter in a greenhouse and plant out in late spring or early summer, after the last expected frosts.
Cuttings of young shoots, June in a frame[200]. Grow on in the greenhouse for their first winter and plant out in spring after the last expected frosts.
Cuttings of half-ripe wood, July/August in a frame[200]. Grow on in the greenhouse for their first winter and plant out in spring after the last expected frosts.
Cultivars
'Album'
A white-flowered form, it flowers prolifically and has a pleasant mild-flavour[K].

Many species are too tender for outdoors in Britain though there are many that can be grown outside.
