Ragged-robin is a lovely but declining plant in the wild due to drainage of its natural wetland habitats. It is an attractive, bushy, upright perennial with loose clusters of 'ragged' pink flowers. It
will grow in a damp position in a lawn, flower border, open woodland or next to a pond in sun or partial shade. It self seeds readily.
Sow July-September in a coldframe, or direct in soil in
autumn. Sow seeds onto the surface of a good, free-draining, damp, seed compost. Cover with a very fine sprinkling of compost or vermiculite. Place sown container in a coldframe or seal inside a
polythene bag and place at a temperature of 15-21C (60-70F) until after germination which usually takes 21-30 days. Do not exclude light as this helps germination.
Alternatively sow seeds in the
autumn, direct into the soil where they are to grow. Seedlings can be thinned the following spring if necessary.
