Alcea rosea 'Spring Celebrities Crimson' - 2026

Alcea rosea 'Spring Celebrities Crimson' is a striking hollyhock cultivar prized for its tall, upright stems adorned with large, fully double, deep crimson flowers that add a bold, dramatic impact to summer gardens. Blooming from mid-summer to early autumn, the vibrant flowers can reach up to 10 cm across, creating an impressive vertical accent in borders, cottage gardens, or along fences and walls. Its rich colour attracts pollinators such as bees and butterflies, supporting local biodiversity while providing a long-lasting display. Hollyhocks are simple to grow from seed or young plants and may self-seed under suitable conditions, ensuring successive blooms in following years. Staking the tall stems and deadheading spent flowers helps maintain their structure and prolong the flowering period, while occasional feeding encourages robust growth and abundant blooms.
