Cette vivace qui tolère la sécheresse, pousse rapidement, produisant de nombreuses fleurs jaunes-or, ressemblant à des chapeaux mexicains, au-dessus d'un feuillage bleu-vert. Fleurit tout l'été. Semez en rangs larges afin de donner un effet de prairie dans votre jardin.

Sow February to June. Place seed on the surface of a good free draining, damp, seed compost and cover with a very fine sprinkling of compost or vermiculite. Seal container inside a polythene bag and place at 15-20C (59-68F). Germination can take 1 to 4 months, but is often quicker. Do not exclude light, as this helps germination.

Transplant seedlings when large enough to handle into pots. Grow on in cooler conditions for 10 to 15 days before planting out after risk of frost, 60cm (24 inches) apart. Plants may prove hardy if wet winter conditions are avoided.
