black fritillary 'Martha Roderick'

Grow in a well-drained soil and full sun, with shelter from rain. Ideal to grow in a cold greenhouse or bulb frame in order to keep bulbs almost dry when dormant. Under glass, grow in loam-based potting compost with added grit and leaf mould

No pruning necessary

Propagate by seed in autumn in a cold frame. Expose to winter cold until germination in spring, then transfer to a cold greenhouse. Divide offsets in late summer

Slugs and lily beetles may be a nuisance

Generally trouble free
