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