Alcea 'Single Mixed' Seeds

   

Excellent choice of flower to grow against a sunny wall or fence, where the tall flower spikes are protected from wind. Usually grown as a biennial, or short-lived perennial. They will self-seed unless the flower heads are removed.

  • Further Information
Common Name: Hollyhock
Plant Type: Biennial
Height: 2.4m
Spread: 50cm
Sowing/Flowering Info:
Sow indoors Mar-April in moist, seed compost. Sow seeds 2cm apart and cover lightly with soil. Germinate at 15-21°C. When large enough, transplant seedlings and grow on in cool conditions. Plant out May-June 30cm apart. Handle by leaves rather than the fragile stem. Direct sow outdoors April-May. Can also be sown undercover June-Aug and overwintered in a greenhouse or cold frame for planting the following year.
Aftercare:
Hollyhocks can be prone to rust, but this can be prevented with a fungicide treatment. Cut back faded flowers to prevent them self-seeding.
