Tall-growing cottage garden favourite. These easy-to-grow perennials are perfect for the back of sunny borders, with fully double blooms in bright colours.
How to sow
Place seed on the surface of good free draining compost and cover with a fine sprinkling of compost or vermiculite. Seal container inside a polythene bag and place at 15-20˚C (59-68F) until after germination which can take 10-12 days. Do not exclude daylight as this helps germination.
How to grow
Transplant seedlings, when large enough to handle, into pots. Grow on in cooler conditions for 10-15 days, before planting out after all risk of frost, 60cm (24in) apart. Overwinter autumn sowings in a coldframe or cool greenhouse and plant out the following spring.
