Which Herbs Grow Well on Windowsills? 8 to Try

A sunny windowsill can turn a plain kitchen into a tiny, tasty garden. If you are wondering which herbs grow well on windowsills, the happy answer is quite a few - provided you match the plant to the light and resist the urge to give every pot a daily drenching.

For children, first-time growers and anyone short on outdoor space, herbs are brilliant little confidence-builders. They grow quickly, smell amazing and make tea, toast, pasta and Sunday lunch feel a bit more special. Snip a few leaves, give them a taste, then watch new growth appear. That is plant, play, grow in its simplest form!

Which herbs grow well on windowsills?

The best windowsill herbs are compact, happy in pots and useful in everyday cooking. A bright sill is ideal, especially one that gets morning or afternoon sun. South-facing windows usually offer the strongest light in UK homes, though a very hot pane in summer can scorch tender leaves.

Here are eight herbs worth making room for.

Basil

Basil is the superstar for a warm, bright kitchen windowsill. Its soft, glossy leaves are perfect for tomato pasta, pizza and a proper homemade pesto. It needs plenty of light and warmth, so it is often happiest from late spring through summer rather than beside a cold winter window.

Keep the compost lightly moist, not soggy, and pick the top leaves regularly once the plant is growing well. Pinching out the growing tips encourages a bushier basil plant instead of one long, leggy stem. If flower buds appear, nip them off to keep the leaves coming.

Chives

Chives are wonderfully forgiving and a top choice for young gardeners. Their grassy leaves pop back after cutting, and the mild onion flavour brightens scrambled eggs, baked potatoes, soups and cream cheese.

They like a bright spot but cope with a little less sunshine than basil. Water when the compost starts to feel dry on top, then cut leaves with scissors a few centimetres above the soil. Their purple pom-pom flowers are edible too, although leaving some to bloom means fewer leaves for a while.

Parsley

Parsley earns its place on the sill because it is useful in almost everything. Flat-leaf parsley has a bold flavour for sauces and salads, while curly parsley is fun for little hands to pick and makes a cheerful garnish.

It takes longer to germinate than speedy herbs such as cress, so patience is part of the game. Once established, parsley enjoys a bright position without fierce all-day heat. Do not strip a small plant bare in one go. Pick a few outer stems at a time and let the centre continue growing.

Mint

Mint smells like summer squash, lemonade and garden games. It grows enthusiastically, which is marvellous in a pot but a reason to keep it in its own container. Give it room and it will soon make a lovely leafy clump.

Mint can manage on a bright east- or west-facing windowsill and prefers evenly moist compost. It may look a little tired if it dries out completely, but it is often quick to recover after a drink. Harvest little and often for mint tea, peas, fruit salads or a very fancy glass of water.

Coriander

Coriander divides dinner tables, but it is a cracking windowsill crop for anyone who loves curries, tacos and zingy salads. Sow a small batch every few weeks rather than relying on one pot, because coriander grows quickly and can flower, or bolt, when it gets too warm or dry.

Place it somewhere bright, water consistently and begin snipping leaves when the plants are sturdy enough. If it starts sending up flower stems, let one plant finish its show. The flowers attract pollinators outdoors, while the seeds can be collected as coriander spice.

Thyme

Thyme is a small but mighty herb with tiny, fragrant leaves. It suits a sunny sill and is much less thirsty than basil, parsley or mint. In fact, overwatering is the fastest way to make thyme unhappy.

Let the top of the compost dry before watering again, and make sure the pot has drainage holes. A few sprigs transform roast potatoes, chicken, mushrooms and vegetable trays. Thyme grows more slowly than some leafy herbs, so harvest gently while it settles in.

Oregano

Oregano loves warmth and sunshine, making it a lovely companion for thyme on a bright windowsill. Its slightly fuzzy leaves bring big flavour to pizza, tomato sauces, roasted veg and Greek-style dishes.

As with thyme, avoid leaving its roots sitting in water. Pick the tips to encourage branching, and give the pot a turn every few days so the plant does not lean dramatically towards the glass. A wonky herb is still an edible herb, of course, but a little rotation keeps growth more even.

Rosemary

Rosemary brings a proper savoury, piney scent to the kitchen. It enjoys lots of light and a free-draining pot, and it would rather be slightly dry than constantly wet. That makes it a good choice for growers who occasionally forget watering day.

Rosemary is slower from seed than many herbs, so a young established plant can be the easier route for instant windowsill success. Snip short sprigs for roast dinners, focaccia and buttery new potatoes. Never remove too much woody growth at once, especially from a small plant.

Light matters more than a fancy pot

Before filling every ledge with herbs, take a minute to notice your window. A south-facing sill tends to suit basil, thyme, oregano and rosemary best. East- and west-facing windows can be excellent for chives, parsley and mint, especially in brighter months. A north-facing sill is trickier, but chives, mint and parsley may still manage if the room is bright.

Glass can make temperatures a bit odd. In winter, move tender herbs away from a freezing pane at night. In summer, shield basil from intense midday scorch if its leaves are bleaching or curling. Herbs like steady conditions, but they are not asking for a spa retreat - just decent light, sensible watering and a pot that drains.

A few small jobs that make a big difference

Use pots with holes in the bottom and place them on saucers to catch drips. Herbs do not want wet feet, so empty any water left in the saucer after a while. Coconut coir is a handy growing medium because it holds moisture without becoming a swamp, but every pot still needs checking rather than watering by the calendar.

Push a finger about a centimetre into the compost. If it feels dry, water gently around the base of the plant. If it feels damp, leave it be and check tomorrow. This simple test is far more useful than guessing from the look of the surface.

Seedlings also need space. If lots of tiny plants have come up in one crowded clump, carefully thin a few so the strongest can grow. It can feel mean, but crowded herbs compete for light, water and food, leading to thin, floppy plants. Think of it as making room for the team to shine.

Turn pots every few days, especially on a narrow sill, so stems grow evenly. And label what you plant. A plant marker prevents the classic family debate: is that coriander, parsley or a very determined weed?

Make harvesting part of the fun

The more leafy herbs are picked, the more they often branch and grow. Start harvesting only once plants have several sets of true leaves and look sturdy. Children can use clean scissors, with an adult nearby for younger growers, and collect snippings in a little bowl for supper.

Take no more than around a third of a plant at one time. Snip basil and oregano just above a pair of leaves, cut chives from the outside, and choose outer parsley stems first. For woody herbs such as rosemary and thyme, take small sprigs rather than giving the whole plant a dramatic haircut.

A windowsill garden will not always look picture-perfect. Basil may sulk in a chilly week, coriander may race to flower and mint may take over its pot like a tiny green monster. That is all part of growing. Try one or two herbs first, enjoy the wins, and add more when you are ready.

Tonight, choose one leaf to taste straight from the sill. A pinch of chives on an egg, a basil leaf on a tomato or mint in a drink is a small, delicious reminder that growing food can start right by the window.
