Providing architectural height to borders, Alcea rosea 'Mars Magic' (Hollyhock) is a robust perennial which produces tall, sturdy spikes of funnel-shaped, brilliant red, single flowers, 4 in. across (10 cm), with a bright buttery-yellow throat. Blooming from mid to late summer, the striking flowers are arranged all round the spike and bloom from the bottom up. An old garden favorite, Hollyhock is best when grown against a wall or fence or at the back of the border.
Alcea rosea 'Mars Magic' belongs to the Spotlight Series, noted for its truly perennial cultivars, not biennial.

- The flowers are attractive to hummingbirds, which hover near the blossoms, and to butterflies. Rabbit resistant.
