Can be sown where it is to flower. So easy, for ‘cottage garden’ borders and ideal for cutting. Exquisite long flower spikes above feathery foliage.
Sow outdoors, March-May or August-October, where they are to flower, 0.5cm (¼”) deep, directly into finely-prepared, well-drained soil, which has already been watered. Seedlings usually appear in 14-28 days. Thin seedlings to 25cm (10″) apart. Water well until plants are established. For a continuous display, make sowings at two to three-week intervals. Sowings made in curves, rather than straight lines, often create a more pleasing effect. Late summer and autumn sowings will flower the following year, often earlier than spring sowings. Flowers: June-September.
Tip: Remove dead heads as soon as they fade as this encourages more flowers to form.
