What to Forage This Week: Four Plants at Peak in Early May

The first week of May is one of the most abundant foraging windows of the entire year. The hedgerows are full, the gardens are generous, and four plants in particular are at absolute peak right now — easy to find, beautiful to eat, and backed by genuinely interesting science. This week’s guide covers lilac, elderflower, dandelion, and white dead-nettle: all widely available across the UK, all beginner-friendly, and between them representing an extraordinary range of bioactive compounds and seasonal flavours.

Lilac (Syringa vulgaris)

Lilac is in flower right now, but you have approximately ten days left before the panicles drop. A large deciduous shrub with heart-shaped smooth leaves and dense upright cone-shaped flower clusters in purple, white, or pale pink. The fragrance is sweet, complex, and unmistakable — you’ll smell it before you see it. Garden walls, old estate lanes, parks, and naturalised hedgerows across the UK.

What to pick: Individual florets only, stripped from the woody central stem. Edible raw or briefly steeped. A 2025 study (PMC13074274) confirmed noteworthy antioxidant activity in lilac flower extracts, with secoiridoids, kaempferol, luteolin, and syringin — a phenylpropanoid with anti-inflammatory and neuroprotective properties in experimental models (PMC12250599). For the full science, recipes (lilac sugar, honey, the lemon infusion that turns pink), see the lilac deep-dive post.

This week’s recipe idea: Lilac florets steeped in near-boiled water for 15 minutes, strained, lemon juice added (watch it shift from pale lavender to pink), drizzle of honey. Or: fold florets through whipped cream for a panna cotta or sponge filling.

Safety: Flowers only. No dangerous lookalikes for the flowers. Never eat any wild or garden plant unless you are 100% confident in your identification. If in doubt, leave it out.

Elderflower (Sambucus nigra)

Elder is a fast-growing large shrub or small tree with strongly pinnate leaves (5–7 leaflets with an unpleasant scent when crushed) and flat-topped clusters of tiny cream-white flowers — the corymbs now opening across the UK through May and into early June. The scent is heady, sweet, and almost muscatel: one of the most recognisable and beloved wild fragrances of the British year.

The science: Elderflowers are exceptionally rich in bioactive compounds. A 2023 study in Nutrients (PMC10489118) confirmed that elderberry flowers are “particularly rich in flavonoids such as kaempferol, quercetin, and rutin” with strong antioxidant and anti-inflammatory properties. A 2021 study (PMC8301142) found S. nigra extract rich in rutin demonstrated “protective capacity for several degenerative diseases.” The triterpene fraction — approximately 3% of dry weight (PMC11354468) — contributes additional anti-inflammatory activity.

Safety note: Elder has one significant lookalike — dwarf elder (Sambucus ebulus), which is toxic. Dwarf elder is herbaceous (not woody), grows lower (60–120cm), has pinkish-purple flower anthers (not cream), and smells unpleasant. True elder is a woody shrub or tree. Learn to distinguish them confidently. The raw flowers are fine in small quantities, but never eat raw elderberries — they contain sambunigrin, a cyanogenic glycoside.

This week’s recipe idea: Classic elderflower cordial — 15 large flower heads, 1kg sugar in 600ml water (cooled syrup), zest and juice of 2 lemons, 1 tsp citric acid. Pour over flowers, cover, leave 24–48 hours, strain. Dilute to taste. Keeps weeks refrigerated.

Dandelion (Taraxacum officinale)

Surely the most recognised wild plant in Britain — hollow stems with milky sap, deeply toothed basal rosette leaves, solitary bright yellow flower heads, familiar spherical seed clocks. All parts are edible: young leaves (more bitter as the season progresses), flowers, and the inulin-rich roots. Peak leaf quality is now, before prolonged summer heat intensifies the bitterness.

The science: Dandelion has one of the strongest evidence bases of any commonly foraged UK plant. Key bioactive compounds include sesquiterpene lactones (taraxacin, taraxacerin), flavonoids (luteolin, apigenin, quercetin, as also found across spring wild plants), chlorogenic acid, and inulin — a prebiotic fibre in the root. A 2011 human clinical study (Pubmed 21991831) demonstrated measurable diuretic activity from dandelion leaf extract — one of the rare foraging plants with actual clinical trial data. The myth of dandelion as a “liver detox” is examined in the dandelion myth-busting post, but the diuretic and antioxidant evidence is genuine.

This week’s recipe idea: Dandelion flower fritters — dip fresh open flower heads (morning, full sun) in batter (flour, egg, milk, pinch of salt), fry until golden, serve with lemon and honey. Or: young leaves in a warm pancetta salad, where the heat and acid of the dressing balances the bitterness beautifully.

Safety: No dangerous lookalikes for experienced beginners — the hollow stem with milky sap, deeply toothed leaves, and solitary yellow head are distinctive. Cat’s ear (Hypochaeris radicata) is similar but has branched stems; also edible.

White Dead-Nettle (Lamium album)

One of the most useful plants for teaching beginners to look carefully. White dead-nettle strongly resembles stinging nettle — similar toothed opposite leaves, similar hairy stem — but produces distinctive white tubular two-lipped flowers in whorls around the stem, and has absolutely no sting. Touch the leaves: completely harmless. It grows 20–60cm tall in disturbed ground, hedgerow bases, roadsides, and garden edges across the UK from now through June.

The science: Significantly underappreciated as a functional food. A 2019 comprehensive review in Nutrients (PMC6571824) described Lamium album as having documented antioxidant, anti-inflammatory, antimicrobial, and antifungal properties. Key bioactive compounds: iridoid glycosides (ajugol, 8-acetylharpagide), flavonoids (quercetin, kaempferol, luteolin, rutin), phenolic acids (chlorogenic acid, rosmarinic acid — also found in ground ivy and rosemary), tannins, and mucilaginous compounds. A 2023 study (PMC10675686) investigated the flowers specifically and found “significant antioxidant and antimicrobial biological properties.” A 2018 study (PMC6278331) found bioactive constituents with activity consistent with traditional use for rheumatic pain relief.

This week’s recipe idea: White dead-nettle and wild garlic soup. Wilt a large bowl of young white dead-nettle leaves with wild garlic (if still available) in olive oil, add hot vegetable stock, blend until smooth, season generously, finish with good olive oil. Earthy, silky, and genuinely satisfying.

Safety: The no-sting quality is the primary identifier. If it stings, it’s stinging nettle — also edible but requires cooking. White dead-nettle is softer, has white tubular whorled flowers, and is harmless raw. Never eat any wild plant unless you are 100% confident in your identification. If in doubt, leave it out.

A Combined Recipe: May Flower Salad

When abundance peaks like this, the best response is to put it all in a bowl.

Dressing

2 tbsp good olive oil, 1 tsp raw apple cider vinegar, 1 tsp raw honey, a pinch of fine salt, a small squeeze of lemon. Whisk together.

The Salad

A base of young tender leaves — white dead-nettle, young dandelion leaves, any mild wild greens you have. Scattered over: fresh elderflower florets stripped from their stems (the tiny cream flowers only), a spoonful of dandelion petals stripped from their green base (remove the bitter green base), and a tablespoon of lilac florets. Optionally: thin-sliced radish and a handful of toasted seeds.

Dress lightly — these flavours are delicate — and eat immediately. Elderflower florets soften quickly once dressed.

What you’re eating: quercetin, kaempferol, rutin, luteolin, rosmarinic acid, secoiridoids, iridoids, sesquiterpene lactones, chlorogenic acid, and prebiotic inulin — all in one bowl, all freshly foraged, all at nutritional peak. This is seasonal eating made literal.

The Week at a Glance

Plant	Peak window	Eat	Caution
Lilac	Now–mid-May	Florets only	Not stems or seeds
Elderflower	Now–June	Flower heads	Not dwarf elder; not raw berries
Dandelion	Year-round; peak now	Leaves, flowers, roots	—

This is the kind of week I run workshops for — when you can forage four distinct plants in forty minutes of walking, cook and eat them the same day, and know exactly what you’re eating and why it matters. Spring workshop dates are still available at chloearchard.com. And the science behind why eating seasonally and diversely makes a measurable difference to your gut microbiome, immunity, and long-term cellular health is the core of The Cellular Reset.
