Indian Spring Mix Hollyhock Seeds

These old-fashioned hollyhocks grow tall stalks of 8-10 feet with beautiful blooms of pink, rose, white, and salmon. The tall blooming spires make for impressive showstoppers and screens in the garden. These plants should be planted in full sun and not allowed to shade other plants that need full sun in the garden. Hollyhocks will bloom the first year from seed if planted early in spring or late winter in mild climates. If planted later, they will bloom the following summer.

Planting by Zones

Zones 9-10

• Hollyhocks are a warm-season flower that can be grown from early spring into the warmer months. 
• Indian Spring Hollyhock will bloom the first year from seed if planted early in spring or late winter in mild climates. If planted later, it will bloom the following summer.

Zones 2-8

• Sow seeds indoors 6-8 weeks before the last frost or direct sow after the danger of frost has passed.

Planting Hollyhock Seeds

• If you start the seeds indoors, use a high-quality seed starting mix. Sprinkle the seed on top of well-moistened soil and cover with 1/4″ of finely sifted soil. Seeds will germinate in 7-14+ days. Wait until seedlings are 3-4 inches tall to be moved to the garden.
• If you wish to direct sow the seeds, sow into well-worked soil that has been finely raked clear of debris. Cover with 1/4″ well-sifted soil.
• Indian Spring Hollyhocks thrive in a wide range of soils and conditions. Plant in a full-sun location. 
• Soil should be kept moist for germination.

Growing Hollyhock

• This old-fashioned flower is easy to grow and makes an excellent cut flower. We grow hollyhocks both for cut flowers and to bring important pollinators to the farm.

Growing Hollyhock in Containers

• If you are planting dwarf hollyhock varieties in containers, make sure your container is at least 10″ deep. We do not recommend planting more than one plant per container as hollyhocks can get large. Keep in mind containers will dry out faster because they have more surface area and less soil to hold onto moisture.
• Full-size varieties such as Indian Spring Mix Hollyhock do not make for good container plants due to their height and foliage size.

Harvesting Hollyhock

• Harvest hollyhock flowers for stunning bouquets that will remind you of summers past. Cut early in the morning for the freshest, longest-lasting blooms. 
• Bees, butterflies, and hummingbirds love hollyhock too! Allow seed pods to develop for reseeding the following year. You can cut the plant’s main stems to the ground at the end of the growing season.

Southern California Pro-tips

• In Zones 9 and 10, hollyhock will grow happily from early spring until fall. Hollyhocks will bloom the first year from seed if planted early in spring or late winter in mild climates. If planted later, they will bloom the following summer.
• DO NOT overhead water as this promotes disease.
• Side dress with an organic granular fertilizer to ensure amble blooms.
• Hollyhock flowers are susceptible to mallow rust, a fungal disease of the leaves. Allow air circulation between plants, avoid overhead watering, and remove plant debris at the end of the season to avoid problems.
