Description: Rare white-flowered form of this popular garden giant! The cascades of tightly-packed florets appear in the second year from the silver-green rosette and can reach an incredible height.

Sowing Instructions: Sow Late May to July at 20-30C (68-86F) on the surface of a good free-draining damp seed compost. Apply a very fine sprinkling of compost or vermiculite, 3mm (1/8in) thick. Place in a propagator or seal container inside a polythene bag until after germination which usually takes 16-22 days. Do not exclude light at any stage as this is beneficial to germination.

Growing Instructions: Pricking out (Transplanting): Transplant when large enough to handle into 7.5cm (3in) pots and overwinter in a cool greenhouse or on a windowsill, giving an optimum temperature of around 7C (45F). Planting out: Plant out the following Spring, 1m (3ft) apart in a well drained soil in full sun.

Aftercare Instructions: Protect plants with a layer of bracken over the winter months.

Caution: Skin Irritant
