What to Forage This Week: Five Plants at Peak in the Late Spring Hedgerow

The British countryside is moving fast right now. Late May is one of those weeks where the hedgerow changes overnight — plants that were shoots last week are flowering, flowers that opened on Monday are setting seed by Friday. If there is a week to get outside and pay attention, this is it.

This week’s guide covers five plants I’ve been finding on my walks recently — all in season right now, all genuinely worth knowing. Several have their own deep-dives on this site if you want to go further. The five: common hogweed, dock, ox-eye daisy, self-heal, and elderflower — which is just beginning to open in parts of southern England and is arguably the most exciting foraging event of the entire year.

1. Common Hogweed (Heracleum sphondylium)

What’s available right now: Young shoots and tightly furled leaf buds — the best stage. Flower bud clusters are beginning to form on more advanced plants. Where to look: Hedgerow bases, road verges, woodland edges. Common and widespread.

Common hogweed’s distinctive essential oil profile — primarily 1-octanol, octyl butyrate, and octyl acetate — gives the plant its characteristic sweet, anise-floral aroma and documented antimicrobial activity (Pubmed 12710728). A 2024 study (PMC11428303) confirmed antioxidant, anti-inflammatory, and antidiabetic properties. The young shoots are nutritionally comparable to other spring vegetables — meaningful vitamin C, vitamin A precursors, and potassium.

Critical safety note: Common hogweed (H. sphondylium) must be positively distinguished from giant hogweed (H. mantegazzianum) before touching. Giant hogweed sap causes severe phototoxic chemical burns. Common hogweed: 50–150cm, green hairy stem, 10–20cm flower heads. Giant hogweed: 2–5 metres, dramatically purple-red blotched stem, flower heads up to 60cm. Wear gloves when harvesting on sunny days. Never eat any wild plant unless completely confident in identification. If in doubt, leave it out.

Recipe idea this week: Hogweed shoot tempura — light rice flour and sparkling water batter, fry at 180°C for 2–3 minutes until pale golden. Serve with a dipping sauce of soy, ginger, and lemon. The batter barely coats the shoot; the flavour is tender, sweet, and complex.

2. Dock (Rumex obtusifolius / Rumex crispus)

What’s available right now: Young leaves are at their sweet spot in May — palm-sized rather than the huge older growth, with the best flavour. Where to look: Everywhere — roadsides, field margins, waste ground, riverbanks.

Dock leaves are high in oxalic acid (giving that sharp, lemony-sorrel flavour), alongside meaningful iron, vitamin C, and potassium. The plant contains anthraquinones — chrysophanol, emodin, physcion — with documented antioxidant and anti-inflammatory activity in vitro (PMC7464605). Phenolic compound analysis of young leaves shows meaningful antioxidant capacity (PMC6680865).

Safety note: High in oxalic acid — those with kidney disease, gout, or a history of oxalate kidney stones should be cautious. Blanching for 90 seconds significantly reduces oxalic acid. Do not confuse with lords-and-ladies (Arum maculatum) — dock leaves have a distinctly lemony-sour smell when crushed; lords-and-ladies does not.

Recipe idea this week: Dock, lemon, and feta fritters — blanched, finely chopped dock leaves mixed with crumbled feta, beaten egg, rice flour, lemon zest, and black pepper. Fry in olive oil until golden. Serve with yoghurt. Sharp, salty, deeply green — a beautiful lunch.

3. Ox-Eye Daisy (Leucanthemum vulgare)

What’s available right now: Flowers opening across southern England — open flowers for petals, tight green buds for pickling. Where to look: Meadows, road verges, chalky banks, field margins. Unmistakable tall white flowers with golden disc centres.

Ox-eye daisy contains sesquiterpene lactones (anti-inflammatory, shared with the Asteraceae family), flavonoids including luteolin and apigenin — a 2025 review (PMC12708091) confirmed potent anti-ageing, anti-inflammatory, antioxidant effects — and iridoids with antioxidant, anti-inflammatory, neuroprotective activities (PMC12056409).

Safety note: Ox-eye daisy and common daisy (Bellis perennis) are completely different plants — different genus, different chemistry. Ox-eye is tall (30–70cm) with large 3–5cm flower heads. Those with chrysanthemum or ragweed allergies should take care — Asteraceae family.

Recipe idea this week: Scatter fresh petals over a warm goat’s cheese and wild herb salad, with a base of blanched dock leaves for sharpness. Dress with olive oil, lemon, sea salt. The white petals against pale cheese and green leaves are visually stunning.

4. Self-Heal (Prunella vulgaris)

What’s available right now: Flower spikes forming and opening — those distinctive hooded purple-violet flowers in dense terminal clusters appearing on short grassland, lawn edges, and path margins. Peak season. Where to look: Lawns, path edges, short grassland, churchyards. Almost certainly in your garden.

Self-heal contains rosmarinic acid (antioxidant, anti-inflammatory, crosses the blood-brain barrier in animal models — the same compound covered in our rosmarinic acid deep-dive), ursolic acid (anti-inflammatory, antitumour activity in vitro), and luteolin. A 2020 systematic review documented antioxidant, antiviral, antibacterial, and anti-inflammatory properties. Traditional use in wound healing and oral health has plausible mechanistic basis.

Safety note: One of the safest wild plants to forage — no significant toxic lookalikes, no known toxicity at culinary quantities. The purple hooded flowers in a dense spike, short stature, and slightly square stem are distinctive.

Recipe idea this week: Self-heal and elderflower lemonade — muddle self-heal flowers with ice, add elderflower cordial, fresh lemon juice, cold sparkling water. The flowers tint the drink a faint lilac. Beautiful and genuinely delicious.

5. Elderflower (Sambucus nigra)

What’s available right now: Just beginning in southern England — the first flat-topped heads are opening. If you are in the South, check your elder trees this week. In the North and at higher altitude, allow another week or two. Where to look: Hedgerows, woodland edges, waste ground, parks, roadsides.

Elderflower is one of the most studied British wild plants. The flowers are rich in flavonoids — quercetin, kaempferol, rutin — with well-documented antioxidant activity. A 2021 review summarised antioxidant, anti-inflammatory, and antimicrobial properties. The extraordinary fragrance comes from volatile aromatic compounds — linalool, nerol, geraniol — that make elderflower one of the most distinctive aromas in the British countryside.

Safety note: Harvest only fully open white flower heads. Do not confuse elder (Sambucus nigra) with dwarf elder (Sambucus ebulus), which is toxic and has an unpleasant smell. Elderflower contains sambunigrin (a cyanogenic glycoside) in very small amounts raw — making cordial or cooking destroys this. Never eat any wild plant unless 100% confident in identification.

Recipe idea this week: Classic elderflower cordial — 1 litre water, 800g sugar dissolved, cooled. Add 20–25 flower heads (stalks removed), zest and juice of 2 lemons, 2 tbsp citric acid. Cover, leave 24 hours. Strain through muslin. Refrigerate. Dilute 1:5. The flavour is incomparable — this is the taste of the British countryside in May.

This Week’s Foraging Summary

• Common hogweed — young shoots and flower buds, roast or tempura
• Dock — young leaves, blanch first, use as a sharp sorrel-like green
• Ox-eye daisy — petals over food, buds for pickling, at peak now
• Self-heal — flowers and leaves, beautiful in drinks and salads
• Elderflower — just opening in the South; make cordial this week

If you’d like to learn to identify all five of these plants in person — I run foraging workshops throughout spring and summer where we walk, find things, taste them, and talk about the science. Details at chloearchard.com.

The connection between seasonal wild food and long-term cellular health — circadian rhythm, epigenetics, the gut microbiome — is something we go deep on in The Cellular Reset. The timing of these foods in your diet matters as much as the foods themselves.
