June Foraging Guide: Sea Samphire, Meadowsweet, and Wild Strawberry
June in the UK offers a treasure trove of edible and medicinal plants coming into their prime. Three standout species — sea samphire, meadowsweet, and wild strawberry — embody the season perfectly: one is a succulent mineral-rich coastal plant, one is the ultimate anti-inflammatory herb, and one delivers concentrated nutrition and polyphenols in a humble berry. Here’s what you need to forage, how to use it, and what the science tells us about why these plants matter.
Sea Samphire: The Mineral-Rich Coastal Greens
Sea samphire (Salicornia europaea) is impossible to miss once you know where to look: salt marshes, coastal mudflats, and estuarine edges from spring through early autumn. The plant grows as succulent, jointed stems — bright green in spring and summer, turning orange, pink, and eventually reddish in autumn. Only harvest the green, tender growth; the older, reddish stems contain excessive salt and silica unsuitable for eating.
The name Salicornia itself derives from Latin sal (salt), reflecting this plant’s natural habitat and character. A halophyte — literally, a salt-loving plant — it thrives where other greens would wilt, soaking up minerals that most vegetables never access: sodium, potassium, magnesium, calcium, and iron. This mineral density makes it far more than a curiosity salad green.
Sea samphire has been consumed for centuries across Europe and Asia. In the UK, it appears as a delicacy in high-end restaurants; in Korea, it is fermented into vinegar and rice wine; in some regions it is dried, powdered, and used as a salt substitute. Recent research has cast new light on why this ancient food tradition persists.
The Science: Functional Nutrients and Antioxidant Power
A 2016 review in 3 Biotech (Patel, 2016) characterized Salicornia as “a halophytic extremophile” with remarkable phytochemical diversity. The plant contains dietary fibres, bioactive polysaccharides, proteins, lipids, sterols, flavonoids, and minerals — an unusually comprehensive nutritional profile. Amongst these, polyphenols and flavonoids are the standouts: these are antioxidant compounds that protect cells from oxidative stress, a known driver of ageing and chronic disease.
The same study notes that whilst high salt, oxalate, and saponin content might seem like drawbacks, these compounds can be removed through simple rinsing or blanching — rendering sea samphire safe and nutritionally dense. More intriguingly, research into Salicornia bigelovii (a cultivated species) demonstrated that when used as a partial salt substitute (1.5% in processed foods), it prevented the hypertensive effects normally associated with sodium chloride, whilst actually improving antioxidant markers including superoxide dismutase activity.
This suggests that sea samphire’s unique mineral and polyphenol profile may offer cardiovascular benefits beyond simple nutrition — a compelling reason to embrace this coastal plant beyond its culinary appeal.
Harvesting and Using Sea Samphire
Forage tender shoots from late May through August, pinching off the top 10–15 cm of stems. Rinse well in fresh water to remove excess salt and sediment. Eat raw in salads (the crunch is distinctive and pleasant), pickle them, or lightly steam and serve as a vegetable. The flavour is briny and mineral-forward — excellent alongside fish, in grain bowls, or simply dressed with lemon and good oil.
Meadowsweet: The Anti-Inflammatory Herb of June
By June, meadowsweet (Filipendula ulmaria) is unmistakable: tall (60–120 cm), with feathery, deeply lobed compound leaves and frothy clusters of tiny cream-coloured flowers that smell of honey, almond, and something ineffably summery. It grows in damp meadows, beside streams, in ditches, and along wet woodland margins across the UK.
Meadowsweet was so prized in medieval times that it is mentioned in historical texts as a “strewing herb” — scattered across floors to scent rooms and repel insects. Its association with mead-making and wellbeing runs deep. But beyond nostalgia, meadowsweet is one of the most studied anti-inflammatory plants in modern phytotherapy.
The Science: Salicylates and Cytokine Suppression
The traditional use of meadowsweet for inflammatory conditions — arthritis, rheumatism, fever, gastric complaints — has a solid biochemical foundation. Like willow bark, meadowsweet contains salicylates: salicin, salicylic acid, and related compounds that suppress inflammation at the cellular level.
A 2023 study published in Pharmaceutics (Van der Auwera et al., PMC10146082) modelled how meadowsweet constituents behave during digestion. The research is illuminating: glycosylated flavonoids such as rutin and hyperoside — which are poorly absorbed in the small intestine — are broken down by the gut microbiota in the colon into absorbable aglycons: quercetin, apigenin, kaempferol, and naringenin. These metabolites, the study found, showed significantly better inhibition of COX-1 enzyme activity compared to COX-2.
COX-1 inhibition matters: COX-1 is involved in baseline inflammation, pain signalling, and gastric protection. The mechanism suggests that meadowsweet’s anti-inflammatory benefit may come not just from its original constituents but from what the gut transforms them into — a reminder that herbal medicine is a conversation between plant chemistry and human biology.
Harvesting and Using Meadowsweet
Harvest the flowering tops in June and July — the flowers and upper leaves carry the most bioactive compounds. Dry them by hanging in a warm, shaded space (they dry quickly and retain colour beautifully). Make an infusion by steeping 1 teaspoon of dried herb in hot water for 5–10 minutes. Traditionally taken 2–3 times daily for inflammatory complaints, though it is best to consult a healthcare provider before using medicinally, especially if you are taking anticoagulants or anti-inflammatory medications.
The flowers are also edible and delicious: scatter them over desserts, steep them in cordials, or use them as an elegant garnish. The entire plant is edible; the roots and leaves are less commonly used in the kitchen but carry the same medicinal compounds.
Wild Strawberry: The Concentrated Nutraceutical
Wild strawberry (Fragaria vesca) is diminutive — the berries barely the size of a fingernail — but their flavour and nutritional density far outstrip their cultivated cousins. Found in woodland edges, hedgerows, meadows, and well-drained grassland across the UK, wild strawberry fruits from May through July. The plant is easily identified by its trifoliate (three-parted) leaves, small white flowers, and miniature red berries.
Unlike cultivated strawberries, which have been bred for size and shelf-life, wild strawberry retains the full spectrum of phytochemicals that evolved to protect the fruit and seed. The entire plant — root, leaf, berry — carries these compounds and is traditionally used for food, medicine, and dye.
The Science: Polyphenols and Cellular Antioxidant Capacity
A 2024 study in PubMed (PMID: 40207736) assessed the nutraceutical properties of wild strawberry and found remarkable polyphenol content. Fragaria vesca fruits contain flavonoids (including quercetin), phenolic acids, terpenes, and organic acids — compounds with well-documented antioxidant and anti-inflammatory activity.
An earlier study from 2014 (PMC4619949) profiled the polyphenolic compounds in both red and yellow wild strawberry fruits, revealing species-specific variation in phenolic acid and flavonoid profiles. Quercetin — one of the most-studied dietary polyphenols — was identified as a major constituent. Quercetin is known to inhibit pro-inflammatory cytokines and support vascular function; its presence in wild strawberry suggests a potential role in cardiovascular and immune health.
What makes this finding particularly significant is that wild strawberry leaves and roots are equally bioactive. The leaves contain many of the same polyphenols as the fruit, making a tea of dried wild strawberry leaf a traditional remedy for diarrhoea, inflammation, and general immune support. Modern analysis confirms the biochemical basis: the polyphenol and tannin content of the leaves is substantial.
Harvesting and Using Wild Strawberry
Forage berries from May through July, eating them fresh or making cordials and jams. Harvest leaves in late spring or early summer (before flowering for maximum nutrient content), dry them thoroughly, and brew as a tea. The flavour is subtle, slightly astringent, and pleasant — often combined with other herbal teas for depth.
Wild strawberry root is also edible and traditionally used, though harvesting roots should be done sustainably and sparingly; only dig where plants are abundant and you are certain of the species.
A Foraging Guide to June
These three plants represent the best of what June offers: coastal minerality, anti-inflammatory flowers, and antioxidant berries. Each plays a distinct nutritional and medicinal role, and together they sketch a foraging map of the season.
When foraging, always prioritise correct identification and harvest sustainably. Sea samphire is most at risk from over-foraging in popular locations; take only what you need. Meadowsweet is abundant and regenerates quickly, so harvesting is low-impact. Wild strawberry is small and scattered, so foraging is naturally self-limiting.
The best foraging days are calm, dry mornings after any dew has dried — this ensures cleaner plants and better preservation of volatile compounds. Bring a small basket, a field guide, and a pair of secateurs if harvesting flowers or woody stems.
Safety and Storage
All three plants are generally safe for the general population, though a few cautions apply:
Sea samphire: High in salt. Rinse thoroughly and avoid if you are on a strict low-sodium diet. Some individuals may experience mild laxative effects from the high fibre and saponin content initially; introduce gradually.
Meadowsweet: Contains salicylates and should be avoided or used cautiously by those with salicylate sensitivity, aspirin allergy, or bleeding disorders. Do not use if pregnant or breastfeeding without professional advice. May interact with blood-thinning medications.
Wild strawberry: Generally very safe. Avoid only if you have a known strawberry allergy. The leaves are astringent and may cause constipation if overused.
Store fresh foraged greens in a plastic bag in the refrigerator (sea samphire and strawberry will keep 3–5 days; meadowsweet flowers are best used fresh or dried immediately). Dry herbs in a cool, dark place in an airtight container; properly dried plant material keeps for 1–2 years.
