Alcea rosea 'O'Hara'

Aptly named scarlet red, double flowers like beautifully scrunched tissue paper, these perennials flower at the back of a sunny border. The doubles all come true from seed, so easy to reproduce. Full sun, 150cm dry soils not too rich.

15 seeds.

The seed we offer can be sown anytime from January to September. Sowing between January and April will require slight warmth (15°C to 21°C) to maintain germination. Later sowings from April to September will not require artificial heat, they will require protection from sudden downpours or extremes of temperature. Seed trays may dry out more easily in summer sun. Further detailed sowing information is sent with the seeds.

Hollyhocks like a well drained and not rich soil, the poorer the better, they require little care, a fertilizer as they come to flowering, but not manure. For more information on Hollyhocks see our cultural section
