This is an easy to grow biennial. Plant seeds now, either where they are to flower, or under cover for planting out 9 inches apart later. Germination can be erratic but they also dislike being transplanted so you are caught between a rockery and hard-landscaping.
The reason I say they are easy, is because they self sow all over my garden and despite the delicate petals I think of them as weeds. So much so that I forgot to photograph any earlier this year.
Other Seeds to sow for next year
- Cerinthe major ‘Purpurascens’ grey leaves with purple bell flowers
- Eschscholzia – Californian Poppy
- Calendula officinalis – Indian Prince mixed coloured pot marigolds
