Summer Carnival Hollyhocks (Alcea rosea) are the epitome of cottage garden splendor, prized for their stately height and dramatic, semi-double, ruffled blooms. This festive mix offers a kaleidoscope of colors, creating a towering vertical statement that draws the eye upward. These classic biennials (often grown as annuals in their first year) are essential for traditional back-of-border planting, where they serve as a living screen or an elegant backdrop for lower-growing perennials.
What are Summer Carnival Hollyhocks?
Summer Carnival is a celebrated series of hollyhocks known for being more compact and earlier-flowering than traditional varieties. They are a favorite in horticultural guides for their ability to bring intense, multi-colored color to the garden without requiring decades of waiting. Their sturdy stems, laden with blooms, are highly sought after by pollinators and gardeners alike.
Why gardeners choose them:
• Towering, multi-colored, semi-double ruffled blooms • Earlier blooming habit than heirloom tall varieties • Perfect for vertical impact in cottage garden backdrops • Excellent pollinator attractors, especially for bees • Dramatic, traditional aesthetic for formal and informal spaces
Growth Habit: Tall, upright biennial (often annual-flowering) Bloom Colors: Vibrant mix of pink, red, yellow, and white Height: 4–6 feet Sun Requirement: Full Sun Sowing Depth: 1/4 inch
Planting Instructions:
• Direct sow in spring or late summer for next year's blooms. • Sow in a sunny, well-drained spot with protection from high winds. • Press into soil and cover lightly with 1/4 inch of compost or soil. • Keep soil consistently moist until germination is established (14–21 days). • Thin to 18–24 inches apart to ensure good airflow and prevent foliage disease. • Stake taller plants in exposed areas to keep their majestic stalks upright.
