Potentilla thurberi, 'Monarch's Velvet'

Germination

Sow into a cold frame in autumn. Surface sow onto moist, well-drained seed compost. Just cover seed with a little soil. Place in a cold frame. Allow autumn warmth followed by natural winter cold to offer ideal conditions for germination to occur as the weather warms in spring. Transplant seedlings when large enough to handle to individual pots and grow on. Acclimatise and plant out after danger of frost has passed.

Growing

Prefers a poor to moderately fertile, well-drained soil in full sun.

Cultivation

This plant might die back at the end of the growing season, if it does not cut back stems to ground level in spring. Propagate by division in spring.
