Hollyhocks grow and thrive with very little help from the gardener.

Hollyhocks are one of those charming old-fashioned flowers grown by our grandmothers. They deserve a place in modern flower gardens, if only for their unusual upright habit that stands out among bushier perennials.

Native to Asia, it is thought that they are one of the oldest flowers in cultivation, grown by the ancient Chinese. Hollyhocks have been found in Stone Age burial sites.

They derive their name from the Old English holi (holy) and hokke (mallow). Another early name for the plant is “St. Cuthbert’s cole.”

The leaves were formerly used as  pot herbs or in salads, best collected in the cool of early winter.

Most hollyhocks are classified as biennials, but there are a few perennial varieties and even a couple of annual varieties. The perennials are short-lived though, often only living 2 to 3 seasons. They self seed readily and will reappear in the garden even years after removing the mother plants.

Sow seeds of hollyhocks in mid to late summer. The plants will return in spring and bloom the following summer. They like full sun and moist, rich, well drained soil. Barely cover the seeds and keep moist until they germinate. Cover the small plants before consistent freezing weather sets in.

Hollyhocks are susceptible to rust and indeed it is the most often heard complaint about them. Removing the two lowest leaves shortly after they appear sometimes helps keep the rust from attacking them. You may be able to contain the rust to the lower leaves even if it does appear. Another option is to plant shorter flowers near them to hide the rust-infected lower leaves.

Water from below and provide plants with a lot of space in which to grow and breathe. Treat plants with fungicide if you cannot tolerate looking at the rust. These measures will sometimes keep rust from attacking. If it does appear, remove the affected leaves and put them in the trash. Do not add to the compost pile.

Hollyhocks are sometimes found growing on abandoned farms or along roadsides. They also make good additions to cottage-style gardens. They grow to heights ranging from one foot up to nine feet. The taller ones work great in the back of the flower garden and the shorter varieties can be tucked in wherever the look of their spikes is desired.
