Grow Your Own Perennial Herb Container Garden

Love herbs? Me too! They grow well in containers so you can grow them anywhere! But if you want them to come back year after year, here is how to grow perennial herbs in a container using the right soil, plants, and growing conditions. Plus, you’ll learn which herbs to plant for the best results.

Perennial Herb Garden

For years now I have been growing herbs in containers just down the deck stairs from the kitchen. While a few changes are made each year, the foundation of this garden is perennial herbs.

The garden will continue to produce for much of the year, allowing me winter harvests of sage, marjoram, rosemary, oregano, and sometimes arugula. Other herbs will pop up in their due time from chives in early spring to saffron crocuses in the fall.

Nothing satisfies the tastebuds and the cooking soul quite like fresh herbs. Plant a herb garden and you may never need to rely on the grocery store for dried herbs every again!

Growing a Perennial Herbs in a Container Garden

Let’s chat about how to actually get started growing your herbs in a container garden. Here’s what you need to consider:

Pick Your Pot

In most cases, larger is better if you plan to over-winter your herb garden container. Pots that are 16”-20” in diameter will allow your herbs to grow into fairly large plants while you continue to harvest them.

For over-wintering, choose plastic pots. You can dress up the area with some smaller terracotta or other decorative pots, but plastic is weather safe and will help protect the roots through the cold.

Use Good Soil

Starting with high-quality potting soil gives your herb garden container the best start. Each year it’s a good idea to scratch in some good compost and replace the soil completely after a few years. Regular feeding throughout the gardening season will encourage healthy growth and strong production.

Site Selection

The best site for your herb garden container is near the kitchen. You aren’t going to love traipsing around in the rain to find herbs at the back of your property. Knowing that your kitchen garden is close by will encourage you to snip away when your meal needs a little extra va-va-voom.

Some herbs like it sunny, hot, and dry, while others prefer a cooler, shadier location. When you choose your plants think of where you are going to place your herb garden container and select accordingly.

What Kind of Herbs Can I Grow Outside in Pots?

There are just so many perennial herbs out there, so the best place to start is to decide what you love and will use. Next, check out your local nursery or ask neighbours to find ideas that just may inspire a new favourite.

Here is some information on just a few of the perennial herbs you can grow in your garden.

flowering herbs for small spaces

Mint, Lemon Balm, and Oregano

Mint is a fast-growing and spreading herb that, while wonderful for teas, cooking and cocktails, can quickly take over the garden. For this reason, mint is best grown in containers. The same is true for lemon balm and oregano. Grow these three in large containers and you’ll always have enough.

Rosemary

In milder areas, rosemary will overwinter but in cooler climates, you should bring plants in for the cold season.

Egyptian Walking Onions

These are fun alliums that have a mild garlic flavour. They set bulbs up at the top of the plant which becomes heavy, flops over, and plants itself in the ground, AKA ‘walking.’

Chives

Chives are so prolific that you’d be hard-pressed to find a gardener nearby who won’t give you a chunk to plant. The pretty purple flowers freeze well and will add a mild onion flavour to soups and dressings. Chive-flower vinegar, anyone?

Tarragon (French)

A sweeter herb with more of an anise flavour that tastes great on chicken or, again, in vinegar. Don’t be fooled by packets of seeds sold as Russian tarragon, it doesn’t stand up in flavour to the French.

Salad Burnet

With a light cucumber flavour, salad burnet is great in (you guessed it!) salads. Leaves can be added to the bowl or used to make a flavoured vinegar or dressing.

Thyme

A wonderful culinary herb for most, but I don’t like the taste. I do love the creeping versions of thyme growing in between pavers though. Check out great cultivars like lemon thyme and woolly thyme, which are exactly what you would expect them to be from their names.

Arugula

Wild arugula has a peppery flavour and hardy temperament. Given enough depth for the long taproot, arugula will produce a small shrub of leafy greens to add to salads and sandwiches.

Chamomile

This beautiful herb has just the most heavenly scent. Dry chamomile flowers for a sleepy-time tea or use them in natural bath products (like this Cold-Process All-Natural Handmade Soap).

Saffron

This expensive herb comes from the bright orange stigmas in the center of the saffron crocus. Pluck the stigmas off frugally, as each flower only produces three of them. This explains why saffron is so darn expensive. You may not be able to grow more than you will use in one recipe, but that’ll be one delicious paella.

Bay

Those large leaves used in soups and stews come from the bay laurel, which is typically trained into a large tree that is as slow-growing as it is beautiful. If you have a friend with one or a spot in the garden, you will never run out of dried bay leaves as a mere few adds a lot of flavour.

Lavender

I can’t say enough good things about lavender. I have many lavender plants in my garden so I can make things like Lavender Eye Pillows, Lavender Bath Salts, Gardener’s Herbal Foot Soak Recipe, Lavender Sachets, and a Dried Lavender Wreath.

Frequently Asked Questions About Perennial Herbs in Containers

What Herbs Are Perennial?

Not all herbs will make it through the winter. For quick reference, some of my favourite perennial herbs include mint, lemon balm, oregano, rosemary, Egyptian walking onions, chives, tarragon, burnet thyme, arugula, chamomile, saffron, bay, lavender, arugula, anise hyssop, sage, and marjoram.

How Deep Should a Container for Herbs Be?

You can use pots for individual plants as small as 10 inches in diameter which are about 3 inches tall.

For an herb container garden, a bigger pot can house multiple herbs. Choose one that is 16 to 20 inches in diameter which is about 14 to 18 inches deep.

What Herbs Should Not Be Planted Together?

Generally, you can group together herbs in a container that like the same environment (light, soil, and water). For instance, group together Mediterranean herbs like lavender, rosemary, thyme, sage, marjoram, and oregano.

Fennel has been known to stunt the growth of surrounding plants and should be kept separate from other plants.

Keep sage away from dill, basil, rye, and any onions. Instead, plant it with thyme, marjoram, and rosemary.

Plants such as mint, lemon balm, and oregano can grow quickly and get invasive, so they might be best left to grow in a container on their own.

  1. Thank you for a wonder post! I’m somewhat confused by parsley, though. I used to think of it a a perennial, because it develops a strong root. Does it not come up year after year if you keep the roots intact?

    • Hi Tatiana, that is a great question and I was just explaining this to someone this weekend! Parsley is a biennial (2-year plant), not a perennial (multi-year plant). This means is that it grows into a the lovely leaves in the first year it is planted, then after winter’s cold temperatures, get huge, flowers, sets seeds, and dies. So you will still want to plant parsley every year to have those delicate and tasty new leaves. I hope this helps!

  3. Hi! Wondering how you “replace the soil completely after a few years”. I have a huge pot with thyme, oregano and rosemary. Just wondering the process you use to replace the soil. Thanks!
