Sowing/Flowering Info:
Sow under glass Feb-Apr or Sep-Nov, in moist seed compost. Lightly cover seed with fine layer of compost and keep at 15-18°C (slightly lower at night). Germination can fail if temperature is too high. When seedlings are large enough to handle, transplant to individual pots. Acclimatise outdoors before planting out when risk of frost has passed. Overwinter autumn sowings until the following year.
Aftercare:
Cut plant back to base in Autumn to avoid wind rock. Deadhead regularly to avoid self-seeding.
