Description
Hollyhocks are classic cottage garden perennials. They provide spires of ruffled, pompom blooms, which are excellent for adding colour and height to summer borders. Plant Hollyhock 'Pleniflora' at the back of borders where their striking blooms will tower over lower growing plants. Height: 180cm (71"). Spread: 60cm (24").

Culinary note: try crystallising the flowers for a tasty cake decoration, or use them to make a delicately flavoured syrup to use with puddings. For more details about edible flowers click here.

Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.

How to Grow
Plant out Hollyhocks in sunny borders in fertile, well drained soil. Choose a position that is sheltered from strong winds. Space hollyhock plants at least 60cm (24") apart to improve air circulation and help prevent hollyhock rust.
More Info
Feed and water regularly until hollyhocks are fully established. Support their tall stems with bamboo canes as the flower spikes develop. In autumn, cut back the old foliage and faded hollyhock flower stems, and apply a mulch of well rotted manure or garden compost to the base of the plant.
