Sow indoors
Almost fill a seed tray with moist seed compost. Sow seeds thinly over the surface, and lightly cover them with a little more compost. Place in the warmth, around 20°C and keep moist.
Grow on
Keep seedlings in a light position, but shade from direct sunlight. When large enough to handle, transplant 5cm apart into trays of potting compost.
Plant out
Gradually accustom plants to outside conditions for 2-3 weeks before planting out when danger of frost has passed. Allow 30cm between plants.
Aftercare
Dead head spent flowers regularly to encourage more blooms. Cut back after flowering. Note that this variety is not a long-lived perennial.
