Description
Chaters Double Mixed Hollyhock Seeds 6515.
Towering Heirloom Spikes Laden with Fluffy, Fully Double Blooms.
Chaters Double Mixed Hollyhock (Alcea rosea) is a grand heirloom favourite that produces impressive, towering flower spikes reaching 2 m in height. Each stately stalk is densely packed with large, fully double, ruffled blossoms featuring a soft cushion centre in vibrant shades of rose, salmon, buff, yellow, red, and crisp white. As a classic biennial, it establishes sturdy foliage rosettes in its first year, followed by an magnificent flowering show throughout the second season. Because Hollyhocks self-seed reliably, sowing them two years in a row creates an ongoing, year-after-year floral display in sunny borders and cottage gardens.

What you need to know to Plant & Grow
Hollyhocks are easy to establish indoors or outdoors, preferring cool germination conditions.
-
Indoor Sowing: Start seeds indoors in a quality soilless starter mix during March. Maintain a cool germination temperature of 18°C for the 21 to 28 day germination period. Avoid higher temperatures, as excessive heat can reduce germination success. Move sprouted seedlings under lights before hardening off and planting outdoors after frost danger passes.
-
Outdoor Direct Sowing: Direct sow seed outdoors anytime from May through August in a sunny location with well-drained soil.
-
Spacing & Care: Space mature plants 45 to 75 cm apart in garden beds to promote proper air circulation and accommodate their tall growth habit. Provide shelter from strong winds or stake plants if planted in exposed sites.
