Flowering

From Early Spring TO Mid Spring

The flowers appear in early to mid Spring

 

Planting

From Mid Spring TO Late Spring

Plant out seedlings when they are big enough to handle. Plant them in to moist, free-draining soil in partial to full shade (although the plants will tolerate a sunny position).

 

Propagating by seed

From Early Spring TO Mid Autumn

Sow indoors at any time or directly in situ any time from early Spring to late Spring, or in the Autumn. Surface sow onto moist, well-drained seed compost. Cover the seed to its own depth with compost or soil. Ideally, chill the seeds at 4°C for 5-6 weeks then return to warmth for germination. (If sown in situ in Autumn in a temperate climate, natural Winter chill will provide ideal conditions for germination to occur as the weather warms up in in Spring).
