Hollyhock 'Nigra' seeds can be sown outdoors in either spring or autumn, taking advantage of the sowing months from February to June and September to October. This biennial thrives in full sun and prefers well-drained soil to develop its striking deep chocolate maroon flower spikes in the second year.
Sow the seeds singly in damp, well-drained soil and cover lightly with soil. To encourage germination, place the sown seeds in a sealed clear container in a sunny spot during the recommended sowing months.
Once seedlings emerge, thin them to allow enough space for growth, as Hollyhock 'Nigra' can develop tall flower spikes that benefit from spacing suited to a 40 cm pot size or garden bed. Providing support may be necessary to keep the tall stems upright during the growing months from May to August.
Water the plants regularly to keep the soil moist but not waterlogged, especially during dry spells in the growing season. Deadhead spent flowers to encourage prolonged blooming and cut back after flowering to maintain plant health and appearance.

A classic cottage-garden biennial with tall spires of blooms, hollyhocks are hardy, pollinator-friendly and full of presence. Loved by bees, they thrive in sunny borders and produce long stems that work beautifully as cut flowers. Once established, they’re reliable, resilient, and often self-seed for future summers.

Native to Turkey and parts of Asia, hollyhocks have been cultivated in Britain since the 16th century. The 'Nigra' variety stands out with its unique dark blooms, adding a modern twist to traditional cottage gardens.

Yes — this is a straightforward packet to give, and what makes it work as a gift is mostly timing. Sowing runs February to June, and September to October, so a packet given inside that window can go straight in, and one given outside it keeps perfectly well until the season comes round.
