Corynephorus is low maintenance but dislikes extremes of wet or dry. Water moderately when necessary. In late Winter, comb fingers through the foliage to thin out any dead leaves and encourage fresh new growth.
Sow December to April or June to July. Sow seed on the surface of a good free draining, damp seed compost and place at a temperature of 20C (69F). Lightly cover the seed with vermiculite. Place in a propagator or seal container inside a polythene bag until after germination which usually takes 14-21 days. Do not exclude light as this helps germination.
Transplant seedlings when large enough to handle into trays or 7.5cm (3in) pots. Gradually acclimatise plants to cooler conditions for a few weeks before planting out after all risk of frost, 30cm (12") apart. Prefers a light, well drained soil in full sun.
When all risk of frost has passed, gradually acclimatise plants to outdoor conditions prior to transplanting them outdoors in any moist, well drained soil in full sun. Plant corynephorus at a distance of 45cm (18") apart.
