Where to Forage in towns and cities?

A guide to knowing where to forage in towns and cities.

Opportunities are everywhere for silent hunters to reap wild food rewards. when you forage in towns and cities!

Most of us now live in urban environments, so knowing where to forage in towns and cities is a necessity if you are wanting to bring exquisite gourmet foods to the table. According to the World Bank, some 54% of the global population live in the urban environment.

Although urban areas are not known for having mile upon mile of fecund hedgerows, or quick and easy access for residents to escape to rolling green hills and woodlands, towns and cities nevertheless harbour enough diversity of habitats to provide for us the majority of the plants discussed.

Before we get on to specific places and the likely suspects to forage for, it’s worth thinking about the different habitats and what they mean to the forager. When you first start to research about where to forage in towns and cities, you will soon discover that habitat identification can be as important as species identifica. An understanding of our landscape, either natural or man-made, with its various bedrocks, soils, and climates, is an ancient and most profitable art.

Knowing what terrain you are walking in, immediately refines the possibilities of what you can expect to find. In towns, this means knowing the little protected pockets, back alleys, streams, railway embankments, parks and cemeteries, as well as having an awareness of climactic effects of the concrete urban sprawl with its distortions in natural phenomenon such as wind speeds and temperatures.

Numerous south-facing sites can be found in towns. The extra solar radiation and warmth of these places always brings heightened productivity. The array of steep banks and verges facing sunwards are often present in abundance in towns, especially where development occurs on hillsides. A south facing slope of just 5˚provide plants with increased photosynthetic radiation equivalent to actually being 400 miles further south (with all the likely positive effects on yields that brings).

Foraging in towns and cities can offer unique opportunities. Often there are extended supplies of fresh edible and medicinal leaves, due to regular strimming and mowing operations. In towns, a ‘heat island’ effect also provides extra warmth, and here the seasonal foraging calendar seemingly undergoes transformation from a chronological procession, to one of mini-cycles of leafy growth, interspersed with flowering wherever plants are lucky enough to escape the chop!

A little historical knowledge of your local area will go a long way when searching for wild foods and medicines. Any city or town of sufficient age will likely have remnants of ancient agriculture within its boundaries or close to. It always pays to know the history of where you live, because local knowledge can be useful for any number of reasons.

When travelling around South-East London for example, it soon becomes apparent that there are a great number of fruit trees and other remnants of the North-West Kentish fruit orchards in that particular area of the once famed garden of England. So the pint here is that its worth doing some research before you leave your door. If you dont know the history of your area you may well miss out on ‘chancing’ upon harvests/

So lets take a look at some specific habitats and settings that are worth exploring, whether in town or country.

Walls, fences, and boundary edges

Plants always grow happiest from any spot that provides satisfactory conditions. I think people could learn a lot from their tenacity. For example hops (Humulus lupulus), can be spotted on many country roads and urban streets in Southern Britain, especially in parts of South East England, usually as it clambers over trees, hedges, walls, and fences.

Hops can also reach high up the sides of large buildings, such as the one I spotted on the Iceland supermarket next to Peckham Rye train station in the heart of urban South East London. This specimen was thriving from an established rootstock, and was easily attaining heights of more than 10 metres. It was dripping with aromatic medicinal flowers come the autumn!

Aside from hops and the regular tangled profusion of ivy, brambles (Rubus spp), roses (Rosa spp), and honeysuckles (Lonicerum spp), you will also find the edible, if bitter, ivy-leaved toadflax (Cymbalaria muralis), with its 2-4 cm wide reniform leaves and dainty little white flowers, passionfruit (Passiflora spp), bittersweet (Solanum dulcamara), and ‘old man’s beard’ (Clematis vitalba) enjoying walls, fences and boundary edges.

These are all naturally sprawling, climbing species. Passionflowers are easily found, voraciously scrambling up and spilling out of private gardens. The grabbing ability of their long tendrils helps it put on lots of growth in just one year.

Walls and fences offer extra warmth and protection from winds, therefore any plants growing against them will generally grow more quickly, flower earlier, and fruit for longer.

Woodland plants

If your town has woods or copses near-by, you will have a chance of finding many different plants during the year. Woodlands are the natural ‘climax’ vegetation of most of Western Europe below mountain tree lines. This explains why a lot of the British flora are natural forest species. Woodlands vary in the flora they harbour, dependent on underlying bedrock and soils, degree of drainage, and human intervention, be this management or mismanagement.

Variable woodland soils hugely affect the flora present. For example, on heavy clay soils; periods of water-logging are common in winter, so a number of the species spotted on marsh or fen land may occur, especially if shade tolerant.

Sandy soils or those on granite or other ancient rock are usually nutrient poor soils, and often very acid (with a pH below 5.5). Here we typically find oak (Quercus spp), birch (Betula spp) or pine (Pinus spp) predominating, with limited under storey diversity, comprising mainly heath-land plants.

On calcerous (lime-rich) soils, the pH is high (usually above 7), and therefore alkaline. The tree species dominating here are typically ash, hazel, and elm, alongside beech in the drier and more southern parts of Britain.

Usually the ground flora on alkaline soils are rich in diversity and may contain many of the species we generally find on chalk scrub or grassland, especially where light levels are raised as in woodland glades, clearings, and rides.

In some areas it may be possible to find plants of acid and alkaline soils almost cheek by jowl, where distinct bedrocks merge, as in parts of Dorset, where acid loving blueberries find pockets of suitable soils near to where farmers grow huge alkaline loving cabbages!

The edges of woodlands offer us many plants also found in the hedgerows. For example, deciduous woodlands often contain raspberries (Rubus idaeus) and dewberry’s (Rubus caesius) as well as blackberries (|Rubus fruticosus agg) in the southern half of Britain.

In Northern areas and higher climes you will increasingly encounter the ‘stone bramble’ (Rubus saxatilis) more frequently and the dewberry not so often. Raspberries are typically found all over Britain, often in well established, dominantly deciduous woodland, either on the edges or within lighter, sunnier areas. Stone brambles, as their name suggests, are seen to enjoy more mountainous terrain.

The yew tree (Taxus bacatta) is an overlooked fruiting plant, probably due to misinformation regarding its poisonous qualities. Many books say the whole plant is poisonous, but these are wrong. The deliciously sweet and gloopy fruit is edible, yet all other parts of this evergreen plant are deadly poisonous, including the seed. The fruits make excellent scary Halloween cake decorations, but eat them carefully and spit the seed out!

The oak tree was formerly used as a food in Britain, especially during famines, most recently in the 1600’s. All bar one of the species you will find here produce acorns with considerable amounts of tannins making them unpalatable raw. However, the oaks are made edible though a number of methods, involving leaching the tannins in water as well as roasting. The one species I know from which you could eat raw acorns, is the evergreen ‘holm oak’, also known as the ‘holly’ oak (Quercus ilex).

Chalk and Limestone grassland plants

Many chalk and limestone grasslands are semi-natural areas of vegetation. Although originally forested, they were cleared a long time ago by man and used as pasture for sheep. They often occur on the more-difficult-to-plough steeper slopes, where chalk or limestone rocks are near the surface. As is the case nowadays, many areas are left un-grazed and soon revert to scrub on its way to the stable climax vegetation of beech or ash. However, certain shrubs and the more light demanding woodland species will also be found. Indeed, these habitats are among the most diverse you will find, and are always more diverse than acid soils.

Amongst the wide array of medicinal and edible plants to be found on alkaline soils are: any one of the plantains (Plantago spp), wild strawberry (Fragaria vesca), red and white clover (Trifolium spp), yarrow (Achillea millefolium), wild carrot(Daucus carota), wild parsnip (Pastinaca sativa), agrimony (Agrimonia eupatoria), salad burnet (Sanguisorba minor), greater burnet (Sanguisorba officinalis), betony (Betonica officinalis syn Stachys betonica), self-heal (Prunella vulgaris), wild marjoram (Origanum vulgare), Juniper (Juniperus communis), and the yew tree. This is but just a small selection.


Just about every town has some wild waterways flowing through them. The convergence of two distinct natural eco-systems, i.e. the land and water, is noted for heightened diversity and productivity of plants and all other organisms. Be sure to be aware of the shifting unstable nature of river banks, ponds and streams.

Many streams and rivers have a noticeable lack of riparian vegetation. Bank-side erosion is inevitable without sufficient buffer strips, for these are the areas immediately around waterways where specific riverside herbs, shrubs and trees soak up surplus water and leached nutrients from elsewhere up-stream and uphill), so where cattle graze, tread, and trample the banks, its vegetation will likely disappear at some point during the year.

Coastal areas

Coastal towns and cities are some of the most productive areas to forage in. Due to the nature of tidal rivers, they have specific vegetation growing there that are comfortable with the more saline conditions, and unless cultivated in gardens, will be hard to find further inland. Estuaries, especially ones with accessible mud and marsh flats, are exceptionally good places to forage from. Depending on where you live, you may well encounter these plants:

  • alexanders (Smyrnium olusatrum)

  • sea-beet (Beta vulgaris)

  • sea kale (Crambe maritima)

  • common and English scurvy-grasses (Cochlearia officinalis / C.anglica)

  • sea purslane (Halimione portulacoides)

  • rock-samphire (Crithmum maritimum)

  • buckshorn plantain (Plantago coronopus)

  • sea plantain (Plantago maritima)

  • marsh samphire / glassworts (Salicornia spp)

  • wild carrot

There are other fine examples of plentiful plants, tasty and highly nutritious, all available to harvest when near the coast. I’ve foraged from small patches of different plantains (Plantago ovata, P.lanceolata, P.media, plus P.coronopus) that I found all hanging out together in Brighton on the beach near the pier. These plants are commonly found on grassy areas in many other coastal towns and cities.

Wastegrounds. Foraging diversity in every every town and city.

Every urban area will have those often neglected, uncultivated pockets of land where many useful species can be found. Our transportation networks have greatly increased bio-diversity in a number of places. This is because plants, most commonly the seeds, have taken advantage of the work of humans to spread their geographic distribution. The habitats created by paths, lanes, highways, bi-ways, rivers, canals, and railway lines can often provide us with heightened diversity.

Disturbed ground, cracks and crevices, and other places

Many of our annual and biennial plants are clever opportunists and survivalists extraordinaire – as anyone can see by the sometimes precarious and unlikely places that our native plants thrive, such as the ones seen jutting out of deteriorating cement in brick walls, especially derelict buildings and derelict yards.

Look out for the renowned traditional cough remedy white horehound (Marrubium vulgare), notable for its downy green-white leaves and white two-lipped flowers, as well as the common white and red dead nettles (Lamium album / L. purpurea) amongst other plants listed previously under waste-grounds.

Certain medicinal species also love to colonise freshly-disturbed ground. These include the poppies (Papaver sominferum and P.rhoes are pretty common), any one of the many willow herbs (Epilobium spp), as well as any number of speedwells (Veronica spp). You would be unlucky not to find shepherds purse (Capsella bursa-pastoris), or a host of the other common edible and medicinal species from the brassica family.

Other frequently found plants include chickweed (Stellaria media) and the widespread mullein (Verbascum thapsus). The profuse-flowering St Johns wort is a lover of ‘poorer’ soils, often found in towns on waste ground, in alleyways, cracks in concrete, as well as in the countryside, abounding on limestone and otherwise calcareous ground.

Areas around allotments will commonly host a large number of species, often including many escaped brassica vegetable plants. Larger fruiting, cultivated blackberry and raspberry varieties often grow up against allotment boundary fences.

Look out here also for alfalfa (Medicago sativa). This plant is best known as a sprouted seed or when planted as a green manure crop, but it also provides us with edible young salad leaves and tasty, pea-flavoured, purple flowers.

Alfalfa is one of our most nutritious foods. It contains vitamins A, B-complexes, C, D, and E. as well as bioflavonoids. It also contains numerous minerals including, Calcium, Magnesium, Phosphorus, Potassium and Zinc. Sprouted seeds are now commonly found in shops, although the plant is quite a common escape. Alfalfa is the plant that the Arabs famously fed to their horses, which began a reputation for Arab hoses, which continues today.

Cemeteries, parks and public gardens

The numerous cemeteries, parks and gardens are exceptionally good places to hunt for plants. They will harbour an array of culinary and medicinal plants. Rosemary (Rosmarinus officinalis) will sometimes still be found in cemeteries, as it has a well documented traditional use as a symbol of remembrance.

Lime trees (Tilia spp) are plentifully found in parks and larger gardens, whilst the seemingly ubiquitous nettle, dandelion, hawthorn, yarrow, burdock, blackberries, plantains, and elder, are also easily found in these increasingly badly and often under-maintained habitats. Municipal flower beds are useful, for here can often be found the smaller, ephemeral plants such as chickweed, speedwells, and hairy bitter-cress (Cardamine hirsuta), in amongst typically unexciting ornamental bedding plants.

In the summer, every town has masses of edible flowers such as Nasturtium (Tropaeolum majus), Calendula officinalis, Viola spp and Campanula spp bursting out of front gardens and escaping through fences.

Commonly found aromatic herbs will likely include lavender (Lavandula angustifolia) and sage (Salvia officinalis), which as evergreen or semi evergreen plants, will allow us foraging opportunities throughout most of the year. As you are by now discovering, many opportunities constantly appear for the urban forager even before considering whether to knock on doors to ask permission.

Commonly ignored edible species.

Many well known plants that are most often planted as ornamental specimens in gardens also offer us edible fruits and valuable medicine. The showy Fushia genus (Onagraceae family) is an example. These plants are often quite vigorous shrubs which can break out of their confines in small gardens. Their often large, and usually pink flowers as well as their oblong-shaped berry fruits (up to 2 cm long on some species) are well worth foraging for as you walk through urban streets. When ripe, the fruits are a dark brown-purple colour, tasting sweet and juicy with a slight peppery after-tone.

The Berberidaceae family of mostly evergreen shrubs are widely planted in towns because they make good hedging. Berberis darwinni offers us citrus flavours from their flowers and a profusion of edible berries in the summer. Mahonia x media and other closely related shrubs that are all commonly known as the ‘oregon grape’ all give us edible, if mostly tart berries in the early summer. These fruits are much improved when made into a preserve! The roots of these plants are valuable digestive herbs.

A common, almost tropical fruit tree, found in most towns these days, is the much planted fig tree (Ficus caricus). They can be thuggish when given anything like a free roam (requiring root confinement to fruit heavily) and easily burst through their enclosing walls and fences. You can often find them by rivers in towns and cities. Their ripe, fat tear-drop-shaped brown fruit are a delicious occasional treat in the late summer and early autumn. Furthermore, I could almost guarantee that near to where you live, you will regularly be going past the plant that gives us the essential flavouring for soups, broths, and casseroles – bay leaves (Laurus noblis).

So get out, explore your local area and discover where to forage in towns and cities.
