Product Details

Alcea rosea. Sow Indian Spring hollyhocks seeds in full sun. This is a selection of our most popular Hollyhocks seeds, blended for planting en masse to create a beautiful cottage garden. Tall spires grow to 2m (6') or more, with single, double, and ruffled flowers that fill in empty garden spaces with blooms in rose, pink, white, chocolate, purple, and lavender. This blend looks sensational from late spring to frost. Hollyhocks are both tall and drought tolerant, so they are a nice choice for xeriscaping. Avoid overhead watering with hollyhocks in order to delay foliar diseases, including rust and powdery mildew. These are not uncommon problems for hollyhocks, but rarely make much impact.

Timing

Timing
Start hollyhocks 6-8 weeks before planting out after the last frost date. In mild winter areas, start seeds indoors in late February to early March, and transplant out in April or May. An early start usually results in flowering the first year. Seeds germinate in 10-14 days. Ideal soil temperature for germination: 15-21°C (60-70°F).

Starting

Starting
Sow seeds on the surface of the soil, and provide bright light. Use peat or coir pots in an effort to minimize root disturbance. Transplant at 45-60cm (18-36″) apart.

Growing

Growing
Grow in rich, moist soil with good drainage and a neutral pH range of 6.0-7.5. The most important factor is good air circulation, so do not crowd plants or plant too close to structures, hedges, etc… Keep well watered and feed a few times during the growing season. If the flower stalk is cut back immediately after finishing, plants may bloom again. Stake tall plants.

Rust is a leaf disease to which hollyhocks are especially prone. It is worse on older plants and can be kept in check by replacing plants every couple of years.
