Collection: Hollyhock Plants

Hollyhocks are best planted in early spring or late autumn in the UK, to allow for a long growing season before any extreme temperatures in summer or winter.

Hollyhocks prefer fertile, well-draining soil which is slightly alkaline, but they tend to thrive in most soils.

Plant your hollyhocks in a sunny, sheltered location where they’ll get around 6-8 hours of sunlight daily, and will be protected from wind.

Water your hollyhocks deeply a couple of times a week, to keep their soil consistently moist but not waterlogged.

Hollyhocks can grow to 2m tall, so although their stems are strong, they will benefit from some support to stop them being blown over. You can use stakes or plant them next to a fence, wall or tree to provide natural support.

Hollyhocks are summer blooming plants, usually starting to flower in June or July and often carrying on right into August or September.

As your hollyhock’s flowers fade, you can cut them off with scissors or shears, and this will encourage the plant to produce more. It also helps to stop your plant self-seeding everywhere!

Hollyhocks are usually grown in the ground, but there’s no reason they shouldn’t thrive in containers, so long as these are large, deep (hollyhocks have long taproots) and have proper support.
