Hollyhock 'Blackberry'
This Double Hollyhock produces towering spires of fully double, rich blackberry-purple blooms that bring bold colour and classic cottage garden charm. Perfect for adding height to borders, fences, and cottage plantings, it creates a striking vertical display through summer. Loved by bees and butterflies, it thrives in full sun and well-drained soil, rewarding gardeners with a long-lasting, romantic floral show.
Sow seeds in spring to autumn in warmer regions, or early spring in cooler areas. Sow directly where they are to grow or raise in trays and transplant carefully to avoid root disturbance. Plant in full sun and well-drained soil enriched with compost. Space 45–60 cm apart for airflow. Water regularly while establishing, then only during dry spells. Stake tall flower spikes in exposed or windy sites. Remove spent stems after flowering to keep plants tidy. Typically grown as a biennial or short-lived perennial in Australian gardens, especially thriving in temperate climates.
