Growing calendar
Sowing & growing
Grow inside from Feb-Jul. Cold is required for germination, so place the seeds in the fridge for two weeks before sowing. Alternatively sow outside from Sep-Dec, let nature do the work for you. Germination should then occur the following spring. When large enough to handle, transplant seedlings into their own pots as they appear.
Aftercare
Cut back spent flower stems the following Spring, so you can enjoy the seedheads for winter interest. Protect from winter wet by planting in the rain show of a tree or shrub.
