Wild flower Dipsacus fullonum is better known as the humble Teasel. This statuesque, thistle-like biennial makes an architectural feature at the back of borders. In its second year, the stiff upright stems are topped with prickly domes of tiny purple-blue flowers. The blooms provide a valuable source of nectar for pollinating insects, and later as the seeds form, they will attract goldfinches to the garden. A fabulous addition to a wildlife garden, where it will self-seed to form attractive drifts. Teasels are undemanding plants, thriving on most soils including heavy clay. Height: 1.5m (5'). Spread: 45cm (18").

1 packet (75 teasel seeds) (KA7463)

Sow February to June 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 propagator or seal container inside a polythene bag at a temperature of 15-20C (59-68F) until after germination which usually takes 1-3 months. Do not exclude light as this helps germination.

Transplant seedlings when large enough to handle into trays or 7.5cm (3in) pots. Gradually acclimatise young plants to cooler conditions for a few weeks before planting them in borders in sun or partial shade. Grow Teasel plants in any fertile, moist soil; including heavy clay soils.

More Info
Water teasel plants regularly until fully established. Dipsacus fullonum will self-seed freely. If seedlings are not wanted, deadhead stems of teasel flowers as the blooms fade. Alternatively leave the seed heads intact as a food source for birds.
