Woodland flowers are at their best at the start of May, but there is still a fair range of species to see even later in the month.
Bluebells usually start the month in full bloom, but soon start to fade, typically at the end of the first week, with some surviving in places into the second. However in 2026 bluebells were over by the start of May and the same was true in 2019, 2014 and 2011 due to hot dry weather in April. In 2025 they were fading rapidly by this point.
By contrast, in 2021 cold weather kept them tentative till the second week of the month, with some lasting right to its end (returning to a pattern also seen in the cold springs of 2013 and 2010). This late in the bluebell season, bracken fronds and cleavers shoots can be a problem in some woods, breaking up the sea of flowers.
Lingering on longer than bluebells are ramsons (commonly known as wild garlic, though they are in fact only a relative of the culinary variety) which are at their best in the first half of May (not till the third week in 2021). In places some can even last until later in the month, however, and at the month's end their dying leaves still give off a pungent garlic smell.
Other April woodland flowers which may survive into the first week of May include lesser celandine, wood anemone, primrose, wood sorrel, violet, ground ivy, ivy-leaved speedwell, wavy bittercress, forget-me-not and goldilocks buttercup (which has narrow leaves and slightly deformed flowers).
As soon as they have finished flowering, the yellowing leaves of lesser celandine become a common sight in woods (more so than on verges, where they are overtopped by other vegetation). Bluebell leaves also lie flat almost as soon as flowering is over and yellow a bit, while wood anemone foliage starts yellowing later in the month, occasionally earlier.
Early in the month you can also see the tall maroon-coloured early purple orchid and the unusual flowers of cuckoo pint. The latter are a lot harder to spot than their leaves are earlier in the year or their red seedheads are in later the summer. Once flowering is over, the envelope surrounding the flower collapses and by the end of the month the seedheads are forming - a cluster of green berries at this stage.
The drooping tassels of pendulous sedge, a plant with thick grass-like blades of vegetation, may also still be in yellow flower at the start of May. They turn brown once they have gone over, but then go green as they produce their seeds. Dog's mercury (which carpets woodland floors and has very inconspicuous flowers in April) has green seeds on its female plants.
Woodland flowers lasting a bit longer into May include garlic mustard and wild strawberry, which are usually over by mid month, and yellow archangel, bugle and greater stitchwort, which may be found into the third or even fourth week. Red campion and herb robert reliably last into June. Towards the end of the month you may see some wood avens (aka herb bennet) on path verges and foxgloves in clearings.
Cow parsley can sometimes occur occur in woodland. If it has not already come into flower in April, it does so in early May, lasting till the second or third week of the month (right to the end of the month in 2021 and 2023).
Pale mauve wood speedwell, more likely in the first half of the month, is easy to confuse with the more conspicuous germander speedwell, which can be found in woods throughout May and whose flowers are larger and generally more blue-coloured. Germander speedwell also has several flowers branching off a stalk with small leaves on, while on wood speedwell there are one or two flowers on an otherwise bare tendril, and it often appears to be only partly out (or over).
As mentioned above, cleavers can cover stretches of woodland floor, as can stinging nettles; both flower inconspicuously in the second half, stinging nettles producing beige tassels and cleavers tiny white stars. Another easily overlooked plant is wood spurge, found mostly in clearings or coppiced areas. Its yellow-green flowers are out early in the month and probably over by the second half, but it is hard to tell which state they are in, frankly.
Rarer woodland species include the ground-hugging yellow pimpernel on the edge of paths and in other bare patches. It is possible throughout the month, and the same is true of the strange umbellifer sanicle, which likes beech woods on chalk. Woodruff, with tiny white flowers and leaves arranged in ruffs to match its name, is often not at its best until mid month.
A specialist grass also found mostly on chalk soils or in beech woods is wood melick, which is an indicator of ancient woodlands. The latter is also true of pignut, usually a meadow flower, but very occasionally found in woods (try Leith Hill in Surrey). On sandy soils you may just come across lily of the valley.
Other rare woodland flowers include coralroot, found only in the Chilterns or eastern Weald, which may survive into May but has usually faded in April. In the first half of the month you might also come across three-nerved sandwort, which looks like a kind of woodland chickweed, while in the second half you might just find some common figwort.
Towards the very end of the month common cow wheat appears in Bleans Woods in Kent and Hockley Wood in Essex, where it is the caterpillar food plant for the rare heath fritillary butterfly.
Meadow flowers
At the start of May, meadows still look like ordinary grassy fields and there is no hint of the transformation that is about to take place. But as the month goes on the grass grows taller, flowers increase, and by mid month you are starting to get the full meadow effect.
An important contributor to this are meadow buttercups, the classic tall buttercup of haymeadows. A few may be seen right from the start of the month, and from mid month they can turn whole fields yellow. (For other buttercups seen in May see Other grassy fields below.)
Meanwhile as the grass grows, more and more of it goes to seed. This makes you realise just how many species of it there are. As early as the second half of April you can see seedheads on meadow foxtail (very common) and in the first half of May bromes - barren, smooth and upright - are also common, dominating many meadows and grassy areas, with upright brome found particularly on chalk soils.
Later in May they are joined by rough or smooth meadow grasses, tall oat grass, and at the very end of the month possibly cocksfoot. Commercial fields are often seeded with perennial ryegrass, which also turns up on grassy margins, and in pasture you get shorter species such as sweet vernal grass and annual meadow grass.
Look more closely at May meadows and you see all sorts of other flowers. One that is very noticeable is common sorrel, which gives a reddish tinge to meadows from quite early in the month. You might also see pignut – a small cow-parsley like flower, once common in haymeadows and cherished for its edible roots (which it is now illegal to dig up...). Just to confuse matters, cow parsley itself occasionally forms large patches in fields.
At a much smaller scale you can see hairy tare, an inconspicuous member of the vetch family which can sometimes take over quite large areas with its tiny pale pink flowers. From around mid month there may be some red clover. Throughout the month the leaves of meadow vetchling are evident and they may just be starting to flower at its end.
Ribwort plantain puts out a delicate white ring of flowers around its seedheads from around the second week, and at the same time you may see common vetch, with its dark pink flowers. Not to be confused with this, and much less common, is grass vetchling, a tiny red flower on a grass-like stem, which may just appear at the very end of the month. Very rarely in damp meadows (and sometimes mysteriously in places that are not the least bit damp) you may see beautiful pink ragged robin.
Also small are the white flowers of common mouse-ear, which can be very prolific in meadows in early to mid May, before their grass gets too tall. Their flowers look very similar to those of lesser stitchwort, which take over from around the middle of the month, and are not phased by tall grass at all. The difference between them is that lesser stitchwort has delicate smooth stems while mouse-ear's are thicker and hairy. Lesser stitchwort also has a slightly larger flower, usually (though not always) with evenly spaced petals, while in common mouse-ear they are grouped in twos (actually one petal with a big notch in it).
Oxeye daisies are a very striking grassland flower that can start to appear in small quantities from quite early in the month, and from mid month can fill some meadows or form large patches in others. Towards the end of the month beaked hawksbeard may make a good showing too, and at the same time rough hawksbeard and hogweed can start to appear, both going on to form quite intense displays in June.
At the very end of the month you may see goatsbeard. This weird plant - which is actually quite common - only opens its yellow flowers in the morning. For the rest of the day all you see is a huge ridged flower bud on a stem with grass-like leaves, or possibly a large grey dandelion-like seedhead.
Other grassy fields
As well as true meadows, in which the grass grows tall, there lots of flowers in May in shorter grassy fields - pasture or other lowland grassland. These too can be dominated by buttercups - sometimes meadow buttercups, but more often by the shorter bulbous and creeping buttercups. Bulbous buttercup, which has turned down sepals under its flowers, is usually the first to appear, in late April, and prefers drier grassland. But both species are common in May, forming intense carpets, particularly in fields grazed by horses.
Dandelions can also still cover grassy fields early in the month, but they are going over rapidly. Briefly their white seedheads can make a good display but they tend to be all gone by the end of the second week.
This is worth noting, because later in May you can see dandelion-like flowers which lead many casual observers to conclude that dandelions flower all summer. In fact, these are hawkbits, hawksbeards and hawkweeds - a confusing group of plants which are described on the May wayside flowers page. One that can occasionally make a good display in grassy fields late in May, as well as on mown suburban verges or village greens, is catsear.
Otherwise in shorter grass note such flowers as germander speedwell, which can form big mats, as well as common and sticky mouse-ear - the latter with clusters of often closed flowers crowded on a single head, while common-mouse ear has more separate flowers. Common mouse-ear in particular can be very prolific in grassy fields. In rougher fields in the second half you may see the very similar lesser stitchwort (see Meadow Flowers above for the difference between them).
In the first three weeks of May bugle can flower in attractive clumps in damper fields, and some small drifts of cuckoo flower linger on in the same habitat well after they have disappeared from path and road waysides. Some midfield patches of greater stitchwort (usually spread from field margins) may also be seen in the first half of the month, and you may just see some surviving ground ivy.
As the month goes on you also see ribwort plantain appearing, as well as the pretty pink-flowered common vetch. You may occasionally see yellow rattle (a parasite on grass roots that keeps grass in check, allowing for other wildflowers) or black medick (a mat-former, which despite its name has tiny yellow flowers).
You might come across patches of crosswort (smelling of honey if you get up close to it), as well as birdsfoot trefoil. An extremely diminutive grassland flower, which could at first glance be mistaken for the eyebright you see on downland in the summer, is thyme-leaved speedwell.
In addition May is a fabulous month for daisies. Though these are more seen in parks, where they can form intense carpets if the grass is left uncut, they also appear in short grass elsewhere, for example on paths and in fields grazed by horses.
Dovesfoot cranesbill crops up in mown or short grass too, as does small-flowered cranesbill; more rarely also common storksbill. Cut-leaved cranesbill may occasionally be seen in taller grass at the end of the month.
White clover can also occur in mown grass, and is seen on grazed fields or paths (it is an indicator of places that are trodden by horses or animals, apparently), with red clover in less trodden spots. Early in the month you may still find good displays of cowslips in grassy fields on chalky soils.
Rougher fields are dotted with the large leaves of dock (often curled or broad-leaved dock) which has similar flowers to common sorrel (see Meadow flowers above), and which may be starting to bloom towards the end of the month. Creeping, spear and marsh thistle plants also grow upwards, though do not flower yet.
Sheep's sorrel, a much smaller version of common sorrel, forms rust-coloured patches in shorter grass, particularly on heathland. In the same habitat, as well as on drier woodland rides, you can see the four-petalled yellow flowers of tormentil, and just occasionally later in the month heath speedwell.
