Roots, Shoots, and Things You've Never Grown: Rediscovering Britain's Heritage Vegetables

Somewhere between the 1950s and today, the British vegetable fell victim to standardisation. Supermarkets wanted consistency — uniform size, reliable shelf life, predictable appearance. Plant breeders delivered. What got lost in the process was an enormous amount of flavour, diversity, and horticultural history.

Walk around a well-stocked seed library or heritage seed fair, though, and you start to get a sense of what we gave up. Kale in colours ranging from deep purple to almost silver-blue. Carrots that are white, yellow, and deep maroon. Turnips the size of a golf ball with a sweetness nothing like the watery giants in supermarket bags. Parsnips with a nuttiness that makes the standard variety taste like cardboard.

This isn't nostalgia for its own sake. Heritage vegetables are coming back because they're genuinely better — better to eat, often better to grow, and better for the kind of biodiversity that makes our food system more resilient. Here's what's happening, who's driving it, and how you can get involved.

The Scale of What We've Lost

The numbers are quietly alarming. In the UK, we've lost an estimated 90% of the vegetable varieties that were commercially available a century ago. Some of those varieties are gone forever. Others survive only in seed banks, private collections, or the care of dedicated heritage seed organisations.

The Henry Doubleday Research Association — now trading as Garden Organic — has been working to preserve heritage vegetable varieties through its Heritage Seed Library since the 1970s. The library holds thousands of varieties that are no longer available commercially, many of them with histories stretching back hundreds of years. Members can access seeds through an annual catalogue, and the organisation's work has helped bring several varieties back from the very edge of extinction.

Real Seeds, a small company based in West Wales, has become one of the most respected sources of heritage vegetable seeds in the UK. They grow and trial everything they sell, and their catalogue reads like a corrective to the sameness of modern vegetable growing. Their approach is explicitly about preserving open-pollinated varieties — seeds you can save yourself, year after year — rather than the F1 hybrids that dominate commercial horticulture.

Kale: Far More Than a Superfood Cliché

Kale has had a strange few years. It went from being largely ignored to being aggressively fashionable to being slightly tiresome — all without most people realising that the kale they were eating represented only a tiny fraction of what the plant can be.

Cavolo nero — the dark, crinkled Italian variety — has become reasonably well known. But heritage British kales are extraordinary in their own right. Ragged Jack, sometimes called Red Russian, has deeply cut, purplish leaves with a tenderness that makes it excellent raw in salads. Cottager's Kale is a tall, branching plant with a flavour that intensifies beautifully after the first frost. Daubenton's Kale is a perennial variety — genuinely unusual in a world of annual vegetables — that will produce leaves for years from a single planting.

For cooking, the key with heritage kales is to match the variety to the application. Tender, smaller-leaved types work raw or very briefly wilted. Larger, more robust leaves benefit from longer cooking — braised slowly in stock with garlic and a little chilli, they become something quite different from the squeaky, slightly bitter kale that put a generation off the vegetable.

The Root Vegetable Comeback

Heritage root vegetables are perhaps the most immediately rewarding category for home growers and cooks, because the flavour difference from modern supermarket varieties is so stark.

Skirret is a root vegetable that was common in British kitchen gardens until the 18th century and then almost entirely vanished. It looks a little like a cluster of small white parsnips and has a sweet, slightly spicy flavour that's genuinely unlike anything available in supermarkets. It's not easy to find commercially, but it's available as seed from specialist suppliers and is straightforward to grow.

Celeriac — not technically a heritage rediscovery, but still criminally underused — has a nutty, celery-like flavour that makes it one of the most versatile vegetables in the winter kitchen. Roasted in chunks with thyme and olive oil, it's magnificent. Grated raw and dressed with a mustard mayonnaise in the French rémoulade style, it's one of the great winter salads. Puréed with butter and a little cream, it makes a more interesting alternative to mashed potato that goes brilliantly with game.

Heritage carrots in non-orange colours aren't just a visual novelty. Purple carrots have a slightly earthier, more complex flavour than the standard orange. Yellow varieties tend to be milder and sweeter. A mixed roasting tray of heritage carrots with honey and thyme is one of those dishes that looks extraordinary and tastes even better.

Forgotten Greens Worth Growing

Beyond kale, there's a whole world of leafy greens that British gardeners and cooks have largely forgotten about.

Good King Henry is a perennial plant that was once a staple of British cottage gardens. The young shoots can be eaten like asparagus in spring, the leaves used like spinach, and the plant will come back year after year with minimal attention. It's almost impossible to find commercially, but easy to grow from seed.

Orache — sometimes called mountain spinach — grows quickly and produces large, arrow-shaped leaves in green, red, or gold. It's more heat-tolerant than ordinary spinach, which makes it useful for summer growing, and it has a mild, pleasant flavour that works well in salads or briefly wilted as a side vegetable.

Land cress is a British native that deserves far more attention than it gets. It has a peppery bite similar to watercress, grows easily in partial shade, and is available almost year-round. Used in salads, soups, or as a garnish, it adds a sharpness that lifts other ingredients without overwhelming them.

Getting Started: Practical Advice for Home Growers

You don't need an allotment or a large garden to start growing heritage vegetables. Many varieties work perfectly well in containers on a balcony or patio. Leafy greens like land cress, orache, and the more tender kales are particularly well suited to container growing.

For seeds, start with Real Seeds, the Heritage Seed Library through Garden Organic, or Chiltern Seeds — all of which carry excellent ranges of heritage varieties with detailed growing notes. Choose one or two things that genuinely interest you rather than trying to grow everything at once.

If growing isn't an option, look for heritage vegetable varieties at farmers' markets, through vegetable box schemes, and from specialist market garden suppliers. Riverford Organic, Natoora, and several regional box scheme operators regularly include heritage and unusual varieties in their deliveries.

In the Kitchen

The cooking principle for heritage vegetables is the same as for any good ingredient: let the flavour speak. Resist the urge to overseason or over-complicate. A heritage carrot roasted simply with a little oil and salt will tell you more about what makes it special than the same carrot buried in a complex sauce.

Season is everything. Many heritage varieties have peak moments — the kale that's sweetest after frost, the turnip that becomes woody if left too long, the salad leaf that bolts in hot weather. Learning these rhythms is part of what makes growing and cooking heritage vegetables so satisfying.

Britain has an extraordinary vegetable heritage. It's taken us a while to start paying attention to it again — but the growers, seed savers, and cooks who've kept these varieties alive are making it easier than ever to reconnect with it.
