Do Hollyhocks Come Back Every Year?

Hollyhocks can bring colour to your garden year after year, but do hollyhocks come back from the same roots every spring? The answer depends on the variety.

Traditional hollyhocks (Alcea rosea) are usually biennial or short-lived perennial plants. Some survive and flower for several years, while others die after flowering. Fortunately, hollyhocks readily self-seed, allowing new plants to grow and replace older ones.

Here at Gardener’s Cottage in Blakeney, North Norfolk, we have grown hollyhocks from seed for many years. With the right growing conditions and a little patience, you can enjoy these beautiful cottage garden flowers summer after summer.

How to Grow Hollyhocks That Return Year After Year

Hollyhocks are a much-loved feature of traditional English cottage gardens, with their towering flower spikes and beautiful blooms in shades of pink, white, yellow, purple and deep burgundy. Growing up to two metres or more, they bring height, colour and a wonderfully old-fashioned charm to garden borders.

But if you are thinking of planting hollyhocks in your garden, or wondering why last year's plants have disappeared, you may be asking the question: do hollyhocks come back every year?

The answer is yes, sometimes – but there is a little more to it than you might think.

Are Hollyhocks perennials?

Most common hollyhocks (Alcea rosea) are biennials or short-lived perennials. This means that an individual plant may live for just two years or may survive and flower for longer.

A biennial hollyhock follows a two-year growing cycle:

• First year: The plant develops a leafy rosette close to the ground, establishing its roots and gathering energy.

• Second year: It produces its tall flower spikes, blooms through the summer, and develops seeds.

• After flowering: The original plant often dies, having completed its life cycle.

This can be confusing for gardeners who expect the same plant to return from its roots every spring.

However, there is good news. Hollyhocks are excellent at producing seeds, and these can grow into new plants, giving the impression that your hollyhocks return year after year.

Will Hollyhocks self-seed?

Yes. One of the easiest ways to enjoy hollyhocks every summer is to let them self-seed naturally.

Once the flowers have faded, seed pods develop along the stems. As these mature and dry, they release seeds which can fall to the ground and germinate when conditions are right.

New seedlings may appear around the original plant, along a garden wall or in other sunny spots throughout your borders.

This natural process is part of the charm of a traditional cottage garden. Rather than planting everything in neat rows, you can allow flowers to pop up in unexpected places, creating a relaxed, informal display.

How to encourage Hollyhocks to return next year

If you would like hollyhocks in your garden every year, try these simple tips:

1. Leave some flowers to go to seed

Resist the temptation to deadhead every flower. Leave a few flower spikes until the seed pods turn brown and dry. You can then allow the seeds to fall naturally or collect them to sow elsewhere.

2. Look out for young seedlings

Keep an eye on the soil around your hollyhocks, particularly in spring and early summer. Young plants initially form a low rosette of leaves, so they can be easy to mistake for weeds.

3. Avoid disturbing the soil too much

Excessive digging or hoeing around your hollyhocks may remove young seedlings before they have a chance to establish themselves.

4. Keep a few spare plants growing

Hollyhocks are not especially long-lived, and some may succumb to disease or fail to return. Allowing several seedlings to grow will help ensure you have flowering plants in future summers.

5. Sow a few extra seeds

For a more reliable display, collect seeds and sow them yourself. This gives you greater control over where the plants grow and helps fill any gaps in your borders.

When should you sow Hollyhock seeds?

Hollyhock seeds are relatively easy to grow, making them a lovely choice for gardeners who want to create a traditional cottage garden without spending a fortune on plants.

There are two main times to sow them.

Spring sowing

You can sow hollyhock seeds indoors in mid to late spring, or directly into the garden in May and June. Grow the seedlings on until they are large enough to plant out.

Plants sown in spring will generally produce their main display of flowers the following summer, although timing varies with the variety and growing conditions.

Summer or autumn sowing

Sowing in summer gives young plants time to develop before winter. They can then establish themselves and flower the following year.

Autumn sowing is also possible, particularly in a sheltered position or under suitable protection.

If you are growing hollyhocks from seed, patience is worthwhile. The reward is a wonderful display of tall, colourful flowers that return to your garden through natural self-seeding.

Where Is the best place to plant Hollyhocks?

Hollyhocks thrive in a sunny position with fertile, well-drained soil. They are particularly effective when planted against a wall, fence or the side of a cottage, where their tall stems provide a beautiful vertical feature.

They are ideal for traditional cottage gardens, where they can be combined with other informal favourites such as hardy geraniums, foxgloves, roses and campanulas.

A few things to remember when choosing a planting position:

• Sunshine: Choose a sunny spot for the best flowering.

• Soil: Well-drained soil is ideal.

• Shelter: Tall stems can be damaged by strong winds, so a sheltered position is helpful.

• Space: Allow enough room for the plants to grow without overcrowding.

Hollyhocks are also suitable for coastal gardens, although exposed sites may require staking to protect the tall flower spikes from strong winds.

Do Hollyhocks flower every year?

Not necessarily on the same plant. Most common hollyhocks flower in their second year, and the original plant may die after setting seed.

However, if you allow seedlings to establish themselves and keep a succession of young plants growing, you can enjoy hollyhock flowers every summer.

For the most reliable results, combine natural self-seeding with occasional sowing of fresh seeds. This also allows you to experiment with different flower colours and varieties.

How do you care for Hollyhocks after flowering?

Once your hollyhocks have finished flowering, you have a choice.

If you want to encourage self-seeding, leave some of the flower spikes in place until the seeds mature. Alternatively, collect the seeds and sow them where you would like new plants to grow.

Once the seeds have been dispersed or collected, you can cut back the old stems and remove tired foliage.

Hollyhocks are susceptible to hollyhock rust, a fungal disease that causes orange-brown spots on the leaves. Good air circulation, removing badly affected foliage and avoiding watering directly onto the leaves can help reduce problems.

Because hollyhocks are relatively short-lived, it is sensible to keep a few young plants growing to replace older ones.

Hollyhocks and the charm of an English cottage garden

There is something particularly appealing about hollyhocks growing beside an old brick wall or framing the entrance to a traditional English cottage. Their tall flower spikes, delicate petals, and informal habit make them a natural fit for the cottage garden style.

They are also a reminder that a beautiful garden does not always need to be perfectly planned. By allowing plants to self-seed, you can create a garden that gradually evolves, with flowers appearing in unexpected places each year.

Here in North Norfolk, cottage gardens are part of the area's timeless appeal. If you love traditional English gardens, coastal walks and the character of historic Norfolk villages, a stay in one of our holiday cottages is a lovely way to enjoy the area and find inspiration for your own garden.

Whether you are planning a garden from scratch or simply hoping to encourage a few more hollyhocks to grow, these beautiful flowers are well worth growing.

Frequently Asked Questions

Do hollyhocks come back every year in the UK?

They can. Individual plants may live for more than one year, but many common hollyhocks are biennial or short-lived perennials. They often return to the garden through self-seeding, producing new plants each year.

Should I cut back hollyhocks in autumn?

You can remove old flower stems after the seeds have matured or been collected. Remove diseased foliage promptly, and leave any healthy seedlings undisturbed so they can establish themselves.

Will hollyhocks survive winter?

Yes. Common hollyhocks are hardy in UK conditions, and their young plants can usually survive winter outdoors, provided the soil is reasonably well drained.

How do I get hollyhocks to flower every year?

Allow some flowers to set seed, encourage new seedlings and sow extra seeds if necessary. Maintaining a succession of plants at different stages of growth is the best way to enjoy flowers each summer.

Do hollyhocks spread?

Hollyhocks can spread through self-seeding. If you allow the seed pods to mature, new plants may appear around the garden. You can remove unwanted seedlings or transplant suitable young plants to a better position.

Do hollyhocks grow well in coastal gardens?

Yes, they can grow well in coastal gardens, particularly in sunny, well-drained positions. In exposed gardens, choose a sheltered spot or support the tall flower stems to protect them from strong winds.

Final thought: If you love the relaxed beauty of a traditional English cottage garden, hollyhocks are a wonderful choice. They may not always return from the same roots, but with a little patience and some natural self-seeding, you can enjoy their beautiful flowers summer after summer.

Please note: This advice relates to traditional hollyhocks (Alcea rosea) and their natural self-seeding habits. Named hybrid varieties may behave differently, and seedlings grown from saved seed may not retain the same flower characteristics as the parent plant.
