This tall hollyhock is a hybrid of Alcea rosea and Althaea officinalis. Far from presenting the slender vertical silhouette of traditional hollyhocks Alcea 'Parkallee' spreads generously in all directions branching from the base to form an open vase shape. Stems are evenly studded with open cupped flowers in light apricot which fades to a buttermilk cream. Each flower supports a central double frill and pronounced bronze stamens from July to September. This plant provides voluminous display requiring a generous 125cm square space in the border to avoid swamping its neighbours.

  • Garden care: Water well during dry spells. To prevent 'rust' from taking hold either spray with Bordeaux Mixture (organic) or Murphy Tumbleblite (non-organic) every 10-14 days. In autumn give the plants a good trim back to 15cm (6in) from the ground.
