Alcea rosea ‘Creme de Cassis’

The hollyhock, Alcea, is a classic English cottage garden plant, forming tall erect racemes of large, fully open blooms from summer to early autumn. Plants are typically perennial, but they’re often grown as biennials due to their susceptibility to the fungal disease rust, which can disfigure leaves.
