Double Hollyhock

Alcea rosea 'Summer Carnival Mixture'

Fluffy double flowers, in a wide range of pastel shades.

Hollyhocks have been grown in gardens for centuries, their tall spikes of satiny, crepe-textured flowers making a fine display in mid-summer. Best at the back of a sunny border, with something in front to hide their bare lower stems. This strain features fluffy double flowers, in a wide range of pastel shades. Plants usually act as short-lived perennials, but will re-seed themselves for many years. The single forms are often said to be more resistant to Hollyhock rust. Attractive to both butterflies and hummingbirds.
