Hollyhocks

Hollyhock (Alcea rosea) is a very tall, upright biennial grown for its spectacular blooms. Many selections are available in all colors except blue. These make excellent choices for a tall border or against a wall or fence where they bloom all summer. They will survive in rocky, dry wastelands or grassy areas. Hollyhocks attract bees and are a host plant for the Painted Lady Butterfly.

• CULTIVATION:
  • Location: Plant in full sun.
  • Soil: They do well in moderately fertile, well-drained areas.
  • Water: Let the soil dry out between watering, and provide deep water periodically.
  • Seasonal care: Cut back old stalks after new growth begins in spring.
• PROPAGATION: Hollyhocks may be started from seed in mid-spring or early summer. Broadcast seed where the plant is to grow. They transplant easily from purchased or homegrown four-inch or six-pac plants. With good conditions, Hollyhocks may reseed naturally.
• PROBLEMS: A rust affects older plants. Remove and replace them periodically. Protect leaves from squirrels.
• SOURCES: Local Nurseries.
