Every week this year, with just one or two exceptions, I’ve taken part in the excellent
#wildflowerhour on twitter where people across the UK share their sightings for the week between 8-9pm each Sunday – an excellent way to draw a weekend to a close.
Many of these photos made an appearance at some point but this is a run-through a few of my favourite wildflower finds or photos from 2016. The absence of orchids can be explained by a whole post all of their own from earlier this week – take a look
Tree flowers are some of the first to make their appearance each year and this set shows a few of these in silhouette against a white February sky. The photo on the left is the male catkins of alder whilst the right two images are the female flowers of two different willow species. Many of these early tree species have both male and female flowers. Some, such as the hazel and alder, have both male and female flowers on the same tree. Others, such as these willows, have male trees or female trees which produce just one type of flower.
An early-morning walk in May treated me to these frosted flowers in Muston Meadows NNR. The sward was still low, with many of the larger, later meadow species such as salad burnet and meadowsweet still to appear, and these smaller early-summer flowering species were the stars of the show. Clockwise from top left are bulbous buttercup, cuckooflower, green-winged orchid and cowslip.
Spring sandwort is a member of the campion family and I came across these cushions of flowers at a disused leadworking site in Derbyshire. It is quite a scarce plant across the UK but frequents these old spoil heaps – such is its connection that leadwort is another name for this flower. I like that this species has specific habitat preferences which are far from the pristine grasslands and woodlands which are associated with the conservation of many species.
This is another example of where a closer look rewards the curious – this is a view down the spadix of an arum lily – also known as Lords and Ladies. This reminds me of one of the plasma balls I used to see in Science Museums when I was younger!
It would be difficult to exclude bluebells from this selection as the sight of a good bluebell wood, with wood anemone, primrose, violets and yellow archangel mixed in, is one of those sights which is profoundly uplifting after a long winter. Many species begin to flower before these, but the bluebell season marks a threshold between the sparsity of spring and the abundance of summer which is just on the horizon. I like the lightness and delicacy of this shot – taken at the Notts Wildlife Trust site – Treswell Wood.
Another photograph from Treswell Wood. I’m not sure I’ve ever seen such an abundance of greater stitchwort than at this site this year – glades were filled with the snow-white flowers of this native woodland specialist.
This is another photograph from Muston Meadows NNR – this time at sunset. I liked the moody, hazy feel of this photograph with buttercups and grass flowers against a darkening sky.
This set was taken on my birthday this year – we were camping just below Old Sarum outside Salisbury and woke up early to climb the old hillside and watch the sun rise. The fields and landscape below were misty and I liked the contrast of these wildflowers against the sunrise haze.Clockwise from top left is dock, cow parsley, nettle and bulbous buttercup.
Smooth tare is a member of the pea family with these tiny white flowers with delicate purple veining. Easily overlooked in a grassland sward, I like the way that they stand out against the soft greens of the surrounding vegetation when you get low enough to appreciate them!
I took a treacherous walk up to the Hills and Hollows on the outskirts of Grantham one very stormy lunchtime in June – somehow these ominous heavens never opened but gave a nice opportunity to capture some common wildflowers against a dark sky. Clockwise from top left is white campion, poppy, white clover and hogweed.
I have a real soft spot for arable weeds – modern farming works hard to eradicate competition from arable fields but many species still find a way to brighten a dull monoculture. This flax field was quite an amazing sight in itself with its array of ripe seeds, but flecked throughout where the glaucous green and delicate mauve of fumitory which scrambled up and through the crop.
Harebells are common in more acidic conditions but can pop up in a variety of habitats. I found them for the first time in the grasslands above Grantham this year, nestled in amongst the Hills and Hollows, but this photo was taken on the Laurie Lee Wildlife Walk in Slad this autumn. You have to get down low to see inside these little flowers, and when i did, I was surprised to find two invertebrate residents settled in for the day. I guess a downwards-facing bell makes perfect cover for a snail to wait until nightfall!
The Longshaw Estate in Derbyshire comes brightly to life with the purple wash of heather in August and this photograph was taken on one of my favourite walks which cuts across this land. The bell heather was frequented by the beautiful heather colletes bees which emerge to coincide with this floral abundance each year, feeding on the flowers and making their nest holes in the sandy soils beneath the roots.
Another from the Peak District – this time the coconut-scented flowers of gorse against a backdrop of heather. The old saying goes, ‘when gorse is out of flower, kissing is out of fashion’ because you can find this species flowering pretty much anytime throughout the year. There are many fewer pollinators at work during the winter, but when a warm day awakens a hibernating bumblebee, it can be fairly sure of a nectar source amongst a stand of gorse.
Whilst I doubt this will be my last wildflower photo of 2016, it seems a nice place to end – a common mallow flower with ice crystals taken on my walk to work in December. A bitterly cold morning, the white edging brought a nice contrast to the deep purple of this flower. Many wildflowers of late-summer will continue flowering until the first hard frosts of winter finish them off so this might perhaps signal the end for this individual!

Salix genus) are one of the earliest flowering tree species in the UK and are a fantastic nectar source for early pollinators such as bumblebees and butterflies. These trees are dioecious which means that there are separate male and female trees which can be distinguished by their flowers. Another more commonly known example of a dioecious tree would be the holly – only the female trees bear the red berries. One of the traditional names for willow flowers was ‘vegetable goslings’ which seems a perfect description to me!
Male willow flowers – the bright yellow pollen is on the end of the stamens and this brushes onto the pollinators when the come to drink from the nectar.
The flowers are quite unusual when compared with a simple flower such as a buttercup which follows the classic textbook diagram. Willow flowers are catkins – these are spikes of numerous tiny flowers rather than each catkin representing a single flower. Each of the yellow-tipped spikes in the male flower is one of the stamens and there are generally two or more of these to each individual flower within the catkin – the number varies with species. The same is true, although less easily illustrated, for the female flowers which have two or more stigmas per flower.
Female willow flowers – these are much less showy and do not have the yellow pollen of the male flowers. They also provide nectar to attract pollinators with the hope that the previous flower visited will be a male willow of the same species and thus the pollen will be transferred and the female flower fertilised.
The male and female flowers appear at the same time in order that the pollen from the male flowers is able to fertilise the female flowers. The flowers are quite different from one another in appearance and, side by side, it would be easy to assume that a male and a female willow tree were two different species.
Development of male willow flowers. On the left you can see the red outer scale to the bud which breaks and the catkin emerges from beneath. The first flowers on the catkin begin to open – the red tipped stamens can be seen. The yellow pollen then begins to be produced and finally the bumblebee comes to drink from the nectar and incidentally collect the pollen whilst doing so. This is an early bumblebee ( Bombus pratorum) and the willow species is Salix x laestadiana which is a hybrid of goat willow and downy willow.
The willow flowers are an excellent source of nectar for early pollinating species, such as queen bumblebees which have emerged from hibernation and are establishing nests, or the early Nymphalidae butterflies which hibernate through the winter.
Small tortoiseshell ( Aglaise urticae) butterfly on female willow flower. Note the presence of the nectar source in the centre of the catkin whilst the yellow-tipped stigma is higher. The stigma is where the pollen must reach in order to fertilise the female flower and this design encourages successful pollination which is an incidental rather than intentional act on the part of the pollinator which is only interested in a free feed!
Unidentified solitary wasp on female willow flower – any ID tips would be most welcome! This demonstrates the effectiveness of the design of the female flower – see how the wasp must bend low into the flower to reach the nectar source, so bringing its body (which will hopefully be dusted with pollen from a male flower) into contact with the female stigma.
