Hollyhock ‘Summer Carnival’ is a cultivated variety of the Alcea rosea plant.

Origins: Hollyhocks are native to Asia and Europe but have been cultivated and naturalized in many parts of the world. ‘Summer Carnival’ is a selected cultivar of hollyhock known for its large, colorful, and showy flowers.

Growth Habits: Hollyhock ‘Summer Carnival’ is a biennial or short-lived perennial plant that produces tall flower spikes adorned with large, ruffled blooms. The flowers come in a range of colors, including pink, red, yellow, white, and purple, often with contrasting centers. ‘Summer Carnival’ hollyhocks typically grow to heights of 5 to 8 feet (1.5 to 2.4 meters) and spread about 2 to 3 feet (60 to 90 centimeters) wide. They are excellent for adding vertical interest to garden borders and cottage-style landscapes.

How to Grow from Seed:

  1. Seed Starting: Start hollyhock ‘Summer Carnival’ seeds indoors 6 to 8 weeks before the last expected frost date in your area. Use seed trays or small pots filled with seed starting mix. Plant the seeds about 6 mm deep and water lightly.
  2. Germination: Place the seed trays or pots in a warm location with temperatures between 18°C to 24°C. Keep the soil consistently moist but not waterlogged. Hollyhock seeds typically germinate within 10 to 14 days.
  3. Transplanting: Transplant the hollyhock ‘Summer Carnival’ seedlings outdoors after the danger of frost has passed and the soil has warmed up. Choose a sunny location with well-drained soil. Space the seedlings about 45 to 60 centimeters apart to allow for proper air circulation and growth.
  4. Support: Install stakes or garden supports around the hollyhock ‘Summer Carnival’ plants to support them as they grow. Tie the main stems to the stakes using soft garden twine to prevent them from bending or breaking under the weight of the flower spikes.
  5. Watering: Water the hollyhock ‘Summer Carnival’ plants regularly, providing about 2.5 to 5 cm of water per week, adjusting based on rainfall and weather conditions.
  6. Fertilizing: Apply a balanced fertilizer or compost around the base of the hollyhock ‘Summer Carnival’ plants every 4 to 6 weeks during the growing season to promote healthy growth and flowering.
  7. Mulching: Apply a layer of organic mulch, such as shredded bark or compost, around the hollyhock ‘Summer Carnival’ plants to help retain moisture in the soil and suppress weeds.
  8. Deadheading: Remove spent flowers regularly to encourage continuous blooming and prevent self-seeding. Cut the flower spikes back to the base once they have finished blooming to promote new growth and flowering.
