An old garden favourite, this short lived perennial only occasionally flowers in its first year. Tall flower spikes up to 2 m form in summer, with usually pink flowers but sometimes shades of red, yellow, cream and white. Flowers may be double or single.
Collect seed in late summer/ early autumn, however colour will not come true if other varieties are nearby.
Sow late winter in pots/modules at 13C for flowers in the same season. Or direct sow in midsummer if treating as a biennial.
