Most people don’t realise that land cress, often called American cress or upland cress, is one of the hardiest salad crops you can grow in a British garden. While watercress grabs all the attention with its riverside growing requirements, land cress delivers that same peppery punch without needing a stream running through your plot. I’ve been growing this brilliant brassica for several years now, and it’s become my go-to winter salad green, surviving frosts that would obliterate rocket or lettuce.
Land cress (Barbarea verna) thrives in the cool, damp conditions we’ve got in abundance here. It’s a biennial plant that’ll give you leaves from autumn right through to spring, exactly when fresh salad ingredients are scarce and expensive. The flavour is sharp and mustardy, perfect for perking up winter sandwiches or adding bite to potato soup. What makes it particularly appealing is that you can grow it in partial shade, where many other crops struggle, and it requires minimal fuss once established. In my Derbyshire garden, it’s self-seeded into corners I’d written off as too damp and shady for anything useful.
This guide will walk you through everything I’ve learnt about growing land cress successfully, from choosing the right spot to harvesting leaves throughout the coldest months. Whether you’ve got a full vegetable patch or just a shady corner by the shed, you’ll find land cress remarkably accommodating.
How To Grow Land Cress
The beauty of growing land cress lies in its simplicity. Unlike fussier crops that demand perfect conditions and specialist equipment, land cress is refreshingly undemanding. Here’s what you’ll actually need to get started.
Seeds and Growing Medium
Land cress seeds are widely available from most garden centres and seed suppliers. You’ll need about 5g of seed to sow a 3-metre row, which should give you plenty of plants. The seeds are small but not tiny, making them easier to handle than some salad crops.
For the growing medium, land cress isn’t particularly fussy. Standard multipurpose compost works fine for starting seeds in modules or trays. If you’re sowing directly into the ground, the soil just needs to be reasonably fertile and moisture-retentive. I’ve had success in everything from heavy clay (common across the Midlands and much of the Southeast) to improved sandy soil, as long as it doesn’t dry out completely.
Location and Space Requirements
You’ll need a spot that gets partial shade, particularly during summer. Full sun can work, but the plants will bolt (run to seed) more quickly, and you’ll need to water more frequently. I’ve found the best results come from areas that get morning sun but are shaded during the hottest part of the day.
Space-wise, allow about 15cm between plants and 20-25cm between rows. That said, I often grow land cress more densely and harvest it as a cut-and-come-again crop, which means you can fit quite a lot into a small area. A 1-metre-square bed can comfortably accommodate 16-20 plants if you’re growing them to maturity, or you can sow more thickly for baby leaves.
Basic Equipment
You won’t need much in the way of tools. A rake for preparing the soil, a dibber or pencil for making planting holes if you’re using modules, and a watering can with a fine rose are the essentials. If you’re growing in containers, choose pots at least 20cm deep with drainage holes. I use old plastic mushroom trays from the grocer’s, which work brilliantly and cost nothing.
A cloche or some fleece can be useful, not for frost protection (land cress laughs at frost) but for keeping the leaves cleaner during winter and deterring pigeons, which seem to have discovered how tasty land cress is during lean months.

Preparing Your Growing Area
Start by clearing your chosen spot of weeds and large stones. Land cress will tolerate less-than-perfect soil, but it performs best when it’s got some organic matter to work with. I dig in a bucket or two of well-rotted compost or leaf mould per square metre, which helps the soil retain moisture without making it waterlogged.
Rake the soil to create a fine tilth on the surface. If you’re sowing in rows, use a draw hoe or the edge of a rake to create shallow drills about 1cm deep. For bed systems, you can broadcast the seed more randomly, which I find works particularly well for cut-and-come-again harvesting. Make sure the soil is moist before sowing, but not sodden. If it’s dry, water the drills thoroughly and let them drain for an hour before sowing.
Sowing Seeds
The best times for sowing land cress are early spring (March to April) for summer harvests, or July to September for autumn and winter crops. I’ve found the autumn sowings far more successful because land cress really comes into its own during cold weather. Spring-sown crops tend to bolt quickly once we hit those long June days.
Sow seeds thinly along your drills, aiming for a seed every 2-3cm. Cover them with about 1cm of soil and firm gently with the back of a rake. Water with a fine rose to settle the soil around the seeds. If you’re growing in modules, sow 3-4 seeds per cell and thin to the strongest seedling once they’ve germinated.
Germination typically takes 7-14 days, depending on temperature. The seeds will sprout in soil temperatures as low as 7°C, which is brilliant for early or late sowings. I’ve had successful germination outdoors in my unheated greenhouse in September when night temperatures were dropping quite low.
Thinning and Transplanting
Once your seedlings have developed their first true leaves (the second set of leaves that appear), thin them to their final spacing. If you’ve sown directly into the ground, remove weaker seedlings to leave plants 10-15cm apart. Don’t throw the thinnings away, by the way. They’re perfectly edible and add a nice peppery kick to salads.
If you started seeds in modules, transplant them when they’ve got 3-4 true leaves. Water the modules thoroughly an hour before transplanting. Dig holes with a trowel or dibber, spacing them 15cm apart, and firm the plants in gently. Water them in well and keep them moist for the first week whilst they establish.
I’ve successfully transplanted land cress up until late October in the Southwest, though in Scotland or northern England you might want to finish transplanting by late September to give plants time to establish before the coldest weather arrives.
Watering and Maintenance
Land cress needs consistent moisture to perform well. In dry spells, water deeply once or twice a week rather than giving frequent light sprinklings. The goal is to keep the soil evenly moist, like a wrung-out sponge. This is particularly important during establishment and if you’re growing in sunnier spots.
During typical British autumn and winter weather, rainfall usually provides enough moisture. I rarely need to water my autumn-sown land cress between November and March unless we’re having an unusually dry spell. Container-grown plants need more attention, though, as pots dry out faster.
Weeding is important whilst plants are small, but once land cress gets going, it forms dense rosettes that suppress most weeds. I just do a quick weed every few weeks to keep on top of things. A light mulch of compost around plants helps retain moisture and adds nutrients gradually, though it’s not essential.
Managing Flowering and Bolting
Land cress is biennial, meaning it grows leaves in its first year and flowers in its second. However, long days and warm temperatures can trigger early bolting, particularly with spring sowings. Once a plant starts to flower, the leaves become more bitter and tougher, though they’re still edible.
To delay bolting, keep plants well-watered and consider using shade netting if you’re growing through summer. Pinch out flower buds as soon as you spot them to prolong leaf production. That said, I usually let a few plants flower because the small yellow blooms are quite attractive and beneficial insects love them. The flowers are edible too, adding a peppery garnish to salads.
If you let plants set seed, land cress self-seeds enthusiastically. I’ve got patches that have reappeared for several seasons now without any effort on my part. Just be aware it can become slightly weedy if conditions really suit it, though it’s easy enough to pull out unwanted seedlings.
Harvesting Your Crop
You can start harvesting land cress leaves when plants are about 10cm tall, typically 6-8 weeks after sowing. For cut-and-come-again harvesting, use scissors to snip leaves about 2-3cm above the base, leaving the growing point intact. The plants will regrow, giving you multiple harvests from the same plants.
Alternatively, pick individual outer leaves as you need them, leaving the central growing point to continue producing. This method works particularly well through winter when growth is slower. Take no more than a third of the leaves at any one harvest to keep plants vigorous.
The flavour is best when leaves are young and fresh. Older leaves become tougher and more intensely peppery, though I quite like them wilted into soups or stir-fries. Morning is the best time to harvest, when leaves are crisp and full of moisture. I’ve found land cress keeps reasonably well in the fridge for 3-4 days if you wash it, dry it thoroughly, and store it in a sealed container.
Common Mistakes to Avoid
I’ve made plenty of errors growing land cress over the years, and seeing others’ struggles at the allotment has taught me even more. Here are the pitfalls worth avoiding.
Growing in Full Sun Without Adequate Water
This is probably the most common mistake I see. Land cress is a moisture-loving plant that naturally grows in damp, shady spots. Stick it in full sun without keeping up with watering, and you’ll get stressed plants that bolt within weeks. The leaves will be small, bitter, and tough.
If you only have sunny spots available, you absolutely must stay on top of watering and consider using shade netting during the hottest months. I learnt this the hard way with a batch sown in April that flowered by early June, giving me barely any harvest. Now I save my sunniest beds for tomatoes and peppers, and tuck land cress into shadier corners where it’s genuinely happy.
Letting Soil Dry Out Completely
Related to the previous point, but worth emphasising separately. Land cress hates drought. If the soil dries out completely, even once, you’ll likely trigger bolting or at least set the plants back significantly. This is particularly problematic with container-grown land cress, which can dry out surprisingly quickly even in cool weather.
Check containers daily during dry spells, and don’t rely solely on surface appearance. Stick your finger into the compost to check moisture levels below the surface. I water my potted land cress most evenings during settled spring weather, even though it might not look necessary.
Sowing Too Early in Spring
Enthusiasm gets the better of many gardeners, me included. We see those first mild February days and rush to sow everything. With land cress, this rarely pays off. Early sowings often sit in cold, wet soil and germinate poorly or succumb to damping off. Even if they do establish, the lengthening days of late spring trigger bolting before you’ve had a decent harvest.
Unless you’re growing in a polytunnel or greenhouse where you can control conditions, wait until at least mid-March for spring sowings. Better yet, focus on summer sowings for autumn and winter crops. That’s when land cress truly excels, providing fresh leaves when almost nothing else is growing.
Ignoring Flea Beetle Damage
Land cress belongs to the brassica family, which means it’s susceptible to flea beetles. These tiny black beetles chew characteristic small holes in leaves, and a bad infestation can decimate young plants. They’re most active during warm, dry weather, typically May to August.
The damage is mostly cosmetic on established plants, but seedlings can really struggle. Cover young plants with horticultural fleece or fine mesh to exclude the beetles. I’ve found that keeping plants well-watered and growing them in shadier spots reduces problems, as flea beetles prefer warm, sunny conditions. By the time you’re harvesting autumn and winter crops, flea beetles have largely disappeared, which is another argument for late sowings.
Harvesting Too Aggressively
It’s tempting to strip plants bare when you need a big batch of leaves for a recipe, but land cress responds better to moderate, regular harvesting. Taking more than half the leaves at once weakens plants and slows regrowth significantly. This is especially true during winter when growth is naturally slower.
I aim to harvest from multiple plants rather than depleting one or two. It takes a bit more time, but you get continuous production rather than boom-and-bust cycles. If you do accidentally over-harvest, don’t write the plants off. Give them a liquid feed and keep them watered, and they’ll usually recover within a few weeks.
Expert Tips
After several seasons of growing land cress in various situations, I’ve picked up a few tricks that make the process easier and more productive.
Succession Sowing for Continuous Harvest
Rather than sowing all your land cress at once, make small sowings every 3-4 weeks from July through September. This gives you plants at different stages of maturity, ensuring you’ve always got productive plants even if some bolt or finish cropping. I keep three batches going: one I’m actively harvesting from, one coming along nicely, and one just getting established.
This approach also spreads the workload. You’re not transplanting or thinning everything on the same weekend, and if conditions aren’t ideal for one sowing (perhaps a particularly hot spell in August), your other sowings compensate.
Pair It With Lettuce for Extended Salads
Land cress’s peppery intensity can be overwhelming on its own, but it’s brilliant mixed with milder leaves. I grow it alongside winter lettuces like ‘Winter Density’ or corn salad (lamb’s lettuce). The combination gives you interesting, complex salads throughout winter rather than just one flavour note.
You can even sow them together in the same bed, as they have similar requirements. The lettuce provides bulk whilst the land cress adds punch. A handful of land cress mixed with two handfuls of milder leaves creates a well-balanced salad that doesn’t blow your head off.
Use It as Ground Cover in Fruit Gardens
This is something I stumbled upon rather than planned. Land cress makes excellent ground cover under fruit bushes and around the base of fruit trees. It tolerates the partial shade, suppresses weeds, and provides a useful harvest from space that might otherwise be bare soil. I’ve got it growing under my gooseberry bushes and around a young apple tree.
The shallow roots don’t compete significantly with established fruit plants, and the dense foliage helps retain soil moisture. Plus, you get edible leaves from areas you’re not using for main crops. Just be aware it might self-seed enthusiastically in these spots, so pull out excess seedlings if they become a nuisance.
Overwinter in Pots for Early Spring Harvests
If you’ve got a cold frame, unheated greenhouse, or even just a sheltered spot against a south-facing wall, sow land cress in pots in August or early September and keep them there through winter. The protection brings harvests forward by several weeks in spring compared to outdoor sowings, and the leaves tend to be cleaner and less weather-beaten.
I use 20cm pots with decent drainage and keep 3-4 plants per pot. Water sparingly through winter (overwatering in cold conditions can cause rot), and you’ll have fresh leaves from February onwards, well before most outdoor crops get going. It’s a small-scale approach, but brilliant for supplementing winter salads when you need just a handful of leaves.
Save Your Own Seed
Land cress sets seed prolifically if you let it flower. In the second year, plants send up flowering stems covered in small yellow flowers, which develop into long, thin seed pods. Let these ripen fully on the plant until they turn brown, then cut the stems and hang them upside down in a paper bag to finish drying.
Shake the stems over a sheet of paper and you’ll get hundreds of seeds that remain viable for 3-4 years if stored in a cool, dry place. I’ve been growing from saved seed for several seasons now, and the plants perform just as well as shop-bought seed. It’s saved me a few quid and given me far more seed than I could ever use, which I share with allotment neighbours.
Frequently Asked Questions
Can I grow land cress indoors on a windowsill?
Yes, though it’s not ideal for long-term production. Land cress can be grown on a bright windowsill, particularly for baby leaves or microgreens. However, most indoor environments are too warm and dry for sustained harvests. The plants will grow tall and leggy searching for light, and they’ll bolt quickly in the warmth. If you want to try it, choose a north-facing windowsill where temperatures stay cool, use deep pots (at least 15cm), and keep the compost consistently moist. I’ve had reasonable success growing it in an unheated porch where winter temperatures stay between 5-12°C, which suits land cress much better than a heated living room.
Is land cress the same as watercress?
No, they’re different plants, though they’re related and taste similar. Watercress (Nasturtium officinale) is aquatic and needs to grow in or beside running water. Land cress (Barbarea verna) is terrestrial and grows in ordinary garden soil, though it prefers moist conditions. The flavour is very similar, with both having that characteristic peppery, mustardy taste, which is why land cress is sometimes called upland cress or American cress. Land cress leaves are generally darker green and slightly more serrated than watercress. Nutritionally they’re comparable, both being rich in vitamins and minerals. For most culinary purposes, you can use them interchangeably, though I find land cress has a slightly more intense flavour.
Why is my land cress flowering already?
Early flowering (bolting) in land cress is usually triggered by stress or inappropriate timing. The most common cause is warm temperatures combined with long day length, which signals the plant to reproduce. Spring sowings are particularly prone to this because plants experience increasing day length and warming temperatures, exactly the conditions that trigger flowering. Other stress factors include allowing the soil to dry out, transplanting stress, or growing in too much direct sun. Once flowering starts, you can’t reverse it, but you can slow it by keeping plants well-watered and pinching out flower buds as they appear. For better results, focus on summer sowings (July to September) for autumn and winter crops, when shortening days and cooling temperatures keep plants in vegetative growth much longer.
Can land cress survive frost and snow?
Absolutely. Land cress is remarkably hardy, surviving temperatures down to about -10°C without protection. I’ve had plants covered in snow for days that emerged completely unscathed once it melted. In fact, many gardeners (myself included) find that a touch of frost actually improves the flavour, making it slightly sweeter and less harsh. The leaves might look a bit battered after severe weather, but the growing points survive and plants bounce back quickly when conditions improve. If you want to protect plants during the worst weather, not for survival but for keeping leaves cleaner and more presentable, a simple cloche or covering of fleece works well. This is more about harvesting convenience than plant health, though. I can harvest usable leaves from outdoor land cress through even harsh winters in the Midlands.
What pests and diseases affect land cress?
Being a brassica family member, land cress shares pest and disease issues with cabbages, kale, and other relatives. Flea beetles are the main pest, particularly on young plants during warm weather, creating small holes in leaves. They’re mostly a problem from May to August and rarely affect autumn-sown crops. Covering plants with fleece or fine mesh during vulnerable periods prevents damage. Slugs and snails will nibble leaves, especially on young plants in damp conditions. I use beer traps and encourage natural predators like ground beetles rather than using pellets. Pigeons have developed a taste for land cress in my area and will strip plants if given the chance, so netting might be necessary in winter when other food is scarce. Disease-wise, land cress is generally healthy. Downy mildew can occasionally appear in very humid conditions, showing as yellowing patches on leaves. Good spacing for air circulation and avoiding overhead watering late in the day helps prevent this.
How long does land cress take to grow from seed to harvest?
From sowing to first harvest typically takes 6-8 weeks under good conditions, though this varies with temperature and season. Spring sowings in warmer soil tend to be quicker, reaching harvest size in about 6 weeks. Autumn sowings made in August or September take longer, more like 8-10 weeks, as they’re growing through shortening days and cooling temperatures. Once you start harvesting, though, the plants continue producing for months. Autumn-sown land cress will crop steadily from October or November right through to April or May of the following year, giving you 6-7 months of harvests from a single sowing. The peak production period is definitely winter, when growth continues even as most other crops have finished. If you’re growing purely for baby leaves as a cut-and-come-again crop, you can start harvesting even sooner, at about 4 weeks after sowing.
Can I cook land cress or is it only for salads?
Land cress is excellent cooked, not just for salads. The peppery flavour mellows with cooking, becoming more subtle and complex. I use it anywhere you might use spinach or watercress. It’s brilliant wilted into pasta at the last minute, stirred through risotto, or added to soups. Land cress and potato soup is a particular favourite, and it makes a lovely base for pesto with walnuts, garlic, and hard cheese. You can also use it in quiches, omelettes, or stir-fries. Because the flavour is quite strong, you typically need less than you would of milder greens like spinach. A couple of good handfuls will flavour a dish for four people. The leaves wilt down considerably when cooked, similar to spinach, so don’t be alarmed when your big pile becomes a small mound. Older, tougher leaves that are less pleasant raw become perfectly acceptable when cooked, so don’t waste them.

Final Thoughts
Growing land cress has genuinely changed how I approach winter salads. Before discovering this hardy little plant, I relied on stored roots and brassicas for fresh vegetables through the cold months, with salads becoming a distant memory until spring. Now I’ve got a reliable source of peppery, fresh leaves right through winter, even during frosty spells that would kill more tender crops.
What I particularly appreciate about land cress is its low-maintenance nature. Once established, it requires minimal input beyond occasional watering during dry spells. There’s no elaborate feeding regime, no staking or training, no complicated pest management. You sow it, thin it, and harvest it. That’s basically the whole process. For gardeners who want productive crops without endless fussing, land cress delivers.
The fact that it thrives in partial shade makes it even more valuable. Most productive vegetables demand full sun, leaving shady spots underutilised. Land cress turns those challenging areas into productive space, filling gaps under fruit trees, beside sheds, or in corners that get limited direct light. I’ve recommended it to several friends who struggle with heavily shaded gardens, and they’ve all been pleased with the results.
If you’re looking to extend your growing season, improve self-sufficiency through winter, or simply try something different, land cress deserves a place in your garden. Start with a small patch this summer, and I reckon you’ll be expanding it next year. The satisfaction of harvesting fresh, flavourful leaves in January whilst everything else looks dormant is genuinely rewarding, and your winter sandwiches will thank you for it.
