Hollyhocks
Heirloom Hollyhocks: The Iconic Skyscrapers of the Summer Garden
Hollyhocks (Alcea rosea) are the definitive symbols of the timeless cottage garden. Reaching heights of six to eight feet, these majestic giants produce sturdy stalks lined with large, saucer-shaped blossoms that command attention from across the landscape. At Firefly Farm & Mercantile, we curate heirloom hollyhock seeds selected for their vibrant pigments and incredible vigor. Acclimated to the cold-winter resilience required in the Driftless Region, our non-GMO varieties provide the architectural height and old-world charm that has captivated gardeners for generations.
A Pollinator Magnet and Backyard Landmark
The secret to a "living" garden often begins with the Hollyhock. Their massive, open flowers are a primary nectar source for bumblebees and butterflies; it is a common joy to see bees "camping out" inside the blossoms as evening falls. Our collection features both traditional Single-Flowered varieties—prized for their pollinator accessibility—and opulent Double-Flowered types that look like silk pom-poms. Whether planted against a rustic fence or used as a dramatic backdrop for shorter perennials, these seeds are the foundation for a spectacular summer display.
Quick Hollyhock Growing Facts:
- Lifecycle: Most hollyhocks are biennials or short-lived perennials. They typically grow a low rosette of leaves in their first year and send up their towering flower spikes in the second year.
- Planting Window: Direct sow in late summer or early fall for blooms the following year, or start indoors 9 weeks before the last frost.
- Sunlight: Requires full sun (6-8+ hours) to achieve maximum height and prevent the stalks from leaning.
- Hardiness: Extremely cold-tolerant; reliable in USDA Zones 3-9.
- Expert Tip (The Airflow Secret): Hollyhocks can be prone to "Rust" (a fungal issue that causes orange spots on leaves) in humid climates. To prevent this, ensure your plants have plenty of space for airflow and try to water at the base of the plant rather than over the leaves. Removing the lower leaves as the plant grows can also help keep the foliage looking clean and healthy!
