What to Forage This Week: Spring’s Five Essential Plants
Tuesday, 31 March 2026 | Season: Spring
There’s a particular magic to late March in the British countryside. The hedgerows are waking up — genuinely waking up — and if you know where to look, five plants are reaching their absolute peak right now. Here’s what’s ready to harvest this week, what each one does for your body, and how to use them.
1. Wild Garlic (Allium ursinum)
What to look for
Glossy green leaves emerging from the woodland floor, hedgerows, and damp meadows. Crush a leaf — you’ll get that unmistakable garlicky smell. The leaves are elongated, smooth, and bright spring green.
Season
Peak now through April. Once flowering heavily, the leaves become tougher.
Nutritional profile
Wild garlic is rich in vitamin C (supporting immune function and iron absorption), selenium, and sulfur-containing compounds called allicins — the same compounds that give garlic its distinctive flavour and much of its medicinal reputation.
The science
A 2024 PubMed study on Allium ursinum found that it accumulates selenium and flavonoids at levels comparable to cultivated garlic, with notably higher vitamin C content. The sulfur compounds are being investigated for anti-inflammatory and cardiovascular effects.
How to use it
Pick the leaves (avoid pulling up the bulb). Wash well, and use fresh in salads, pestos, or wilted into soups and egg dishes.
2. Stinging Nettles (Urtica dioica)
What to look for
Serrated, heart-shaped leaves on square stems, covered in tiny hairs that sting. Pick the top 10–15cm of young growth. Wear gloves when harvesting.
Nutritional profile
Nettles contain approximately 25–30% protein (by dry weight), making them one of the highest-protein wild greens. They’re rich in iron, calcium, magnesium, and manganese — minerals that are bioavailable. A 2015 study found nettle leaves supply 90–100% of daily vitamin A and are an outstanding source of dietary calcium.
The science
Nettle’s anti-inflammatory reputation comes from flavonoids and polysaccharides that inhibit inflammatory pathways. A randomised controlled trial found patients applying fresh nettles to arthritic joints experienced significantly greater pain relief than placebo.
3. Hawthorn Leaves (Crataegus monogyna)
What to look for
Emerging on hawthorn trees along hedgerows. Young leaves are bright green, deeply lobed, and tender. Pick from trees that haven’t yet flowered.
The science
Hawthorn has one of the strongest evidence bases of any herbal plant for cardiovascular support. A 2012 systematic review found hawthorn extract shows consistent benefits for heart failure symptoms, including improved exercise tolerance.
4. Dandelion Leaves (Taraxacum officinale)
What to look for
Rosettes of deeply toothed leaves hugging the ground. Young spring leaves are tender and less bitter. The paler inner leaves are less bitter than dark green outer ones.
Nutritional profile
Dandelion leaves are rich in vitamins A and K, and contain taraxasterol and polyphenols. They’re also a source of inulin, soluble fibre that feeds beneficial gut bacteria.
The science
A 2024 review found dandelion contains bioactive compounds with antioxidant and anti-inflammatory properties. The inulin makes dandelion a prebiotic food supporting beneficial bacteria growth.
5. Sheep’s Sorrel (Rumex acetosella) / Garden Sorrel (Rumex acetosa)
What to look for
Heart-shaped leaves (garden sorrel) or smaller arrow-shaped leaves (sheep’s sorrel) with a distinctive lemony tang. Found in meadows, grassland, and gardens.
Important note — oxalic acid
Sorrel is high in oxalic acid, which can bind calcium and iron in the gut. For most people eating small amounts, this isn’t a concern. However, if you have kidney stones, gout, arthritis, or rheumatism, be cautious. Cooking reduces oxalic acid. A reasonable guideline: no more than 50g fresh sorrel per day.
Safety Notes
Identification
Never eat any wild plant unless you are 100% confident in your identification. Some toxic plants superficially resemble edible ones. Invest in a good UK field guide or forage with someone experienced.
Foraging location
Avoid busy roadsides, industrial areas, and treated agricultural land. Forage from clean, ideally pesticide-free areas.

Always consult your GP before using wild plants medicinally, particularly if you are pregnant, breastfeeding, or taking medication.
