How to Create a Secret Garden
Part 1: How to Grow Hollyhocks from Seed (Beginner Guide)
There are certain flowers I grow every year, no matter what.
Hollyhocks are one of them.
From the first season I planted them, I was hooked. Tall flower spikes stacked with blooms. Bees working their way up and down each stem. Butterflies stopping in the afternoon light. They change the feel of a space quickly.
Now I make sure the farm is never without them. Every year, at least one packet of hollyhock seeds goes in.
They’re part of my morning and evening farm walks. In the morning, I’ll stop and watch bees collecting pollen. In the evening, I often find a bee tucked inside a bloom for the night. In the afternoon, they’re one of the best flowers on the farm for butterfly watching.
If you want to create a garden that feels full, layered, and alive, growing hollyhocks from seed is one of the simplest ways to start.

What Are Hollyhocks?
Most hollyhocks (genus Alcea) are biennials.
That means:
- Year one: leafy growth
- Year two: tall flower spikes
Many beginner gardeners are surprised by this. Waiting a full season for blooms isn’t always appealing.
But there’s an exception.
How to Get Hollyhock Flowers the First Year
If you want blooms this season, plant Hollyhock ‘Indian Spring.’
This is the variety I recommend to beginners because:
- It can bloom the first year from seed
- It grows 5–6 feet tall
- It comes in classic cottage garden colors
- It’s reliable and easy to grow
In central New Jersey (Zone 6b/7a), I’ve:
- Started seeds indoors in mid-February
- Hardened off in early March
- Transplanted by late March
I’ve also direct sown seeds as soon as the soil was workable — even when patches of snow were still on the ground. The seeds handled freezing nights without issue.
If you’re starting your secret garden this year, this is the variety I’d choose.

Plant early, and you can have tall blooms this summer.
When to Plant Hollyhock Seeds (Simple Regional Guide)
Instead of a complicated zone chart, here’s the practical version:
Northern States
- Start indoors 8–10 weeks before last frost
- Or direct sow once soil is workable in early spring
Mid-Atlantic & Similar Climates
- Start indoors late winter
- Or direct sow very early spring
Southern States
- Direct sow in late winter
- Fall planting also works well
If the soil isn’t frozen solid and you can work it, you can plant.
How to Grow Hollyhocks from Seed
Growing hollyhocks from seed is straightforward:
- Choose a sunny location (6+ hours daily)
- Loosen the soil
- Press seeds lightly into the surface
- Cover with about ¼ inch of soil
- Water gently
- Keep soil lightly moist while seeds germinate (7–14 days)
That’s all you need.
What Does “Self-Seeding” Mean?
After blooming, hollyhocks form seed pods.
If you leave them on the plant:
- The pods dry.
- They open.
- Seeds fall to the soil.
Next spring, new seedlings appear nearby.
That’s called self-seeding.
Over time, your planting fills in naturally. You can also collect seeds and scatter them where you want more plants.
A Little Support, If They Need It
Hollyhocks grow tall — often five or six feet, sometimes taller.
Most seasons they stand on their own. After heavy rain or strong wind, you might see one leaning.
If needed, a bamboo stake beside it, tied loosely with twine is usually enough support.
What to Do After Blooming
When the flowers are finished:
- Cut the stalk down to the base.
- Leave the plant in place.
If it’s a perennial variety, it will return. If it’s a true biennial finishing its life cycle, seedlings may already be growing nearby.
You don’t need to dig anything out unless you want to.
Are Hollyhocks Good Cut Flowers?
Some seed companies market hollyhocks as cut flowers.
In my experience, they’re better left in the garden.
You can harvest when only the lowest blooms are open and condition carefully, but vase life is short. In the landscape, they provide height, pollinator activity, and visual impact that’s hard to replace.
Other Hollyhock Varieties We Grow and Recommend
Once you’ve grown hollyhocks for a season or two, it’s hard not to add more. These are varieties we’ve grown and liked for different reasons:
Double Majorette Blend
A shorter, double-flowered mix with full, layered blooms. A good choice for smaller gardens or front-of-border planting.

Growing Hollyhocks in New Jersey (And Similar Climates)
If you’re local to Hopewell, Princeton, Montgomery, or nearby areas of central New Jersey, hollyhocks perform especially well here.
Our late winters allow for early direct sowing. Cool springs support strong root development. And by early summer, those tall flower spikes fit naturally into older homes, farm fences, and backyard borders.
If you’re nearby and interested in garden coaching or plant selections suited specifically to our region, we’ll be sharing more about that soon.
Start with One Thing
If you want a secret garden that feels layered and alive, you don’t need to plant everything at once.
Start with one thing.
For me, hollyhocks are always that first layer. They bring height, pollinators, and structure.
Plant a packet this season.
