WHEN TO SOW
March to June
WHERE TO SOW
Sow seed on the surface of lightly firmed moist seed compost and cover with a very light sprinkling of vermiculite. Place sown container in a propagator or a warm place at a temperature of 15-20°C (59-68°F). After sowing do not exclude light as this helps germination.
WHAT TO DO NEXT
When large enough to handle, transplant seedlings into pots or trays. Then plant out into borders when plants are large enough in the autumn after sowing, or over winter plants in a cold frame and plant out the following spring.
June to July (the following year)
Allow the flower spikes to dry into the late Autumn before cutting down, so that the seed is scattered to produce flowers the following year.
