Spring is finally here!

Well, it seems to have been a long time coming, but spring is finally here. The trees are at their greenest and the time for sowing seeds is coming towards an end. Our proven flower mixes continue to delight throughout the UK, for instance, on the Island of Jersey and at Fulham Palace, London,  providing a spectacular pop of colour for locals and visitors alike. It's great to have such good feedback, and we would like to thank all our regular customers for their continued support.

And our new specially designed native seed mixes have been proving popular too - e.g. Haywards Heath town council are using our new Highways mix on verges around the town, so look out for roadsides full of wildflowers later in the year, helping support our pollinators.

Our work can also be seen in a new book; we were asked to supply photographs for ‘New Wild Garden’, by Ian Hodgson, published by Frances Lincoln, so look out for shots of our flower mixes in all their glory.




And speaking of books, see below for a chance to win a copy of 'The Bee Book', co-authored by our very own Steve Alton.

Hedge Your Bets

The FlowerScapes corporate hedge, which replaced a rather dull stretch of Lonicera nitida a few years ago, is really starting to bear fruit, quite literally. Last year we had our first few Spindle berries, and this year they have been joined by the translucent red fruits of Guelder-rose. Rose hips and Blackberries have been a feature for a few years now, and hopefully Sloes will be coming on line soon.


We’ve always been great advocates of native hedging. As well as providing an effective stock- and people-proof boundary, they provide shelter and nectar for a wide range of other species but also act as an interface between people and wildlife. One face of your garden hedge supplies you with food and colour, but the other face looks outward, displaying its wonders to passers-by. And if people want to do a little foraging as they pass, that’s fine with us.

Then, of course, there’s the flora of the hedge bottom, that strange twilight habitat that is neither woodland nor meadow, but shares features of both. Sadly, though, recent studies suggest that this habitat is suffering. Traditionally, the hedgerow was a last bastion against intensive farming; even the most zealous tractor-driver couldn’t get too close, so they remained relatively free from pesticides. True, many were grubbed up to make larger fields; just after the end of World War II there were over 800,000 kilometres of hedges in Britain, but by 1990 there were only 171,000 kilometres left, a loss of almost 80%. But of the ones that survived, the very best could represent fragments of remnant woodland going back thousands of years.

Recent research by Prof Dave Goulson, of the University of Sussex, suggests that neonicotinoid pesticides, used as a seed treatment on a range of crops, are starting to appear in hedgerow flowers, sometimes at far higher levels than in the crop itself.

It appears that as much as 94% of the neonicotinoids applied to the crop end up in the soil, where they accumulate over the years and are washed out to the field margins. And the margins, of course, are where most of our pollinators will carry out their foraging.

A paper by researchers from the University of Plymouth found that, along hedgerows that formed the boundary between arable fields and roads, bumblebee abundance was twice as high on the road-facing side of the hedge compared with the crop-facing side.  This is probably partly to do with herbicide effects in the field, but also down to the presence of road-verge grassland habitat adding further floral diversity.

So maybe now is the time to consider planting, not only a native hedge, but our road-verge seed mix too? It sounds like another habitat that urgently needs our help.

It’s always good to have studies to back up what we think we know, even if it sometimes feels like stating the obvious. A recent study by Sussex’s Dave Goulson and Lorna Blackmore of the University of Sterling, demonstrated that plots sown with a ‘wildflower’ seed mix had 5 times more flowers, 50 times more bumblebees and 13 times more hoverflies compared to paired control plots. The seed mix used in this study was a generic native wildflower mix, mainly perennials with a handful of cornfield annuals. Our UK Native Wildflower Mix or indeed our Perennial Bee Mix would give a similar effect.

Boosting road verge biodiversity for bees

The FlowerScapes corporate holiday this year took us to Denmark, where we were struck by the quality of the road verges. Not just the occasional road verge, but pretty much every verge was a riot of colour, with rather more yellows and blues than we’re used to in this country, thanks to abundant chicory and assorted umbellifers.



British road verges are starting to catch up, partly through the reduction of mowing for money-saving reasons, but also through a genuine desire by local authorities to encourage wild flowers. Rotherham seems to be particularly forward-thinking in this regard, with long stretches of flowering verge around the town, and signs like the one below starting to appear.

At  FlowerScapes we have long been advocates of the use of non-native species to extend the flowering season of pollinator mixes – a practice supported, incidentally, by the new report from the RHS (see below) – but we have also always been careful to stress that there are situations where native-only mixes not only could but absolutely should be used. Rural road verges are a case in point, where there may be existing native semi-natural vegetation – nature reserves, SSSIs, etc – nearby.

To that end, we are very pleased to introduce our new low-growing native mix designed specifically for road verges where the preservation of sight-lines is a requirement. It contains a selection of attractive, colourful native wildflowers. The mix, once established will only need mowing once a year, but it can be mowed more frequently if required.

And for urban road verges where the requirement for native species is less of an issue, we have an urban road verge mix, which benefits from the addition of a range of low-growing northern hemisphere favourites. Research suggests that an abundance and diversity of flowers leads to a greater bee abundance and bee species richness along roadsides that are restored. (Hopwood, 2008).

So if you are involved in projects where the seeding of verges is prescribed, and want  to give biodiversity a boost, then consider our Highways mixes, and help feed our declining pollinators at the same time!



The first research paper to emerge from the RHS Plants for ‪Bugs project has just been published. This experiment has demonstrated that using plants from only a single region of origin (i.e. nativeness) may not be an optimal strategy for resource provision for pollinating insects in gardens. Gardens can be enhanced as a habitat by planting a variety of flowering plants, biased towards native and near-native (Northern Hemisphere) species but with a selection of exotics to extend the flowering season and potentially provide resources for specialist groups.

Go Wild in the Country



I’ve just finished reading ‘Feral’, by George Monbiot. I have to admit that I approached it with some trepidation; I’m a big fan of Mr Monbiot, and I was conscious from reading his blog that there were aspects of his latest book that I was going to find uncomfortable.

Monbiot’s thesis is this; that we have lost touch with nature, and since we evolved within a dynamic and often dangerous natural environment, its absence affects us at the deepest level; that to remedy this we need to re-wild the landscape and reconnect with it; and that to achieve this we need to recreate the processes, generally involving large herbivores and the predators that preyed on them, which created that wild landscape.

So far so good; nothing there I would argue with. On the contrary, I’m a strong believer in the need to get young people in particular out into ‘wild’ places, to get wet and get their hands dirty. Interestingly, Monbiot suggests that we have a deep need for the excitement and adrenaline that would have been a regular part of life alongside large predators, which may explain why video games are so popular. I have to confess I have spent too many hours myself either pursuing or being pursued by aliens, zombies and other imaginary foes across virtual landscapes; the modern-day natural world struggles to supply quite the same rush.

You don't see many of those in Sussex...
But it is on the subject of rewilding where George and I start to part company, and I’ll attempt to explain why.

The principle makes complete sense; the majority of our native species evolved in a landscape of woodland interspersed with clearings. The exact size and origin of these clearings is a subject for debate, but herds of large mammals, flooding by rivers, disease and natural disasters would all have created open spaces in what would otherwise have been dense temperate rainforest. With the arrival of humans, most of those open glade species would have slotted into the new habitats created by agriculture; meadows, ploughed fields, hedgerows and the like. Even in the remaining woodlands, cyclical coppicing would have created a mosaic of temporary glades.

A coppiced woodland

So there is much to be said for Monbiot’s suggestion that we stop managing our wild places and let woodland return, then allow large mammals to do their thing, creating the structural diversity that brings species richness. But there are problems.

We are all, necessarily, influenced by our own experiences. Much of Monbiot’s thinking on the subject of rewilding seems to be based on his experiences in the uplands, specifically the part of Wales where he lived, which he refers to as the Cambrian Desert. Now, it’s pretty widely accepted, at least in conservation circles, that the uplands are massively overgrazed by sheep, or ‘sheepwrecked’ as Monbiot calls it. Sheep are one of the few grazing animals not to have had a wild ancestor in post-glacial Britain; horses and cattle both had their forebears, but sheep came from much further south. Their effect in the uplands has been to eradicate almost all of the humid Atlantic-fringe rainforest, dripping with mosses and lichens, which would have been the natural vegetation, replacing it with short turf and heather moorland. One effect of this has been to speed up the movement of water off the hills, resulting in flooding in the lowlands. The other effect, of course, is a complete change in the flora and fauna.

They look so innocent, too.

So rewilding in the uplands would be a marvellous thing, for all kinds of reasons. But to extrapolate and apply this thinking to the whole of the British Isles is to take things too far. Conventional conservation, as practiced by the Wildlife Trusts, gets a particularly vicious kicking from Monbiot. The Wildlife Trusts, he claims, are perpetuating the problem of loss of ‘wilderness’ by trying to emulate the agricultural methods of some historical ‘golden age’. By using grazing animals as a conservation tool, they are preventing the land from doing what it would otherwise do, which in most cases means returning to woodland (‘self-willed’ land is a popular buzz-phrase in the rewilding community). Instead of grazing, mowing and clearing scrub from the meadows, chalk downs, heaths and fens, Monbiot seems to be saying, the Wildlife Trusts – and other ‘traditional’ conservation practitioners – should step back and let the landscape run free.

To me, this seems entirely the wrong way round. Nature reserves, whoever they are managed by, tend to be sanctuaries for a whole suite of very habitat-specific species. By definition; if they weren’t habitat-specific, presumably they would be all over farmland, town and cities. By managing these reserves using the techniques that created them, these species are allowed to survive; if all these sites were allowed to return to woodland, only woodland species would win. On Ashdown Forest, for instance, the Conservators use grazing animals as a conservation tool. But they aren’t specifically trying to maintain traditional framing practices, though that may be a by-product. What they are attempting is to reproduce the disturbance that would have created the mosaic of woodland and open spaces in which heathland species existed before humans came along. If they stopped, the Forest would quickly revert to birch and oak woodland and many species would be lost. Take, for example, the Small red damselfly. This is a species of acid, boggy pools in open heathland, and because that habitat is pretty rare, so is the damselfly. If the Forest reverted to woodland, it would almost certainly disappear.

It's small. And red. And it's a damselfly.

It is my suggestion that nature reserves should, in fact, be the last places to be rewilded. Britain possesses vast tracts of farmland where we, as taxpayers, pay an increasingly small number of landowners subsidies to farm. In total, the government gives out £3.6bn in farm subsidies each year; the biggest 174 landowners in England take £120m between them. In order to receive their money, farmers must prevent ‘unwanted vegetation’ – wildlife habitat, in other words – from growing on their land, even if it is not currently producing food. Even worse, we pay some of the wealthiest people in the country to manage the moors for grouse, for their own pleasure and profit! Surely, somewhere within this system, it must be possible to find space for rewilding? 

Some people are trying; Sir Charles Burrell has removed all the gates on his Knepp Castle estate and allows deer, cattle, ponies and pigs to roam free. The resulting meat is sold at a premium. If this model could be extended, then perhaps we would begin to see the return of the processes that created the dynamic, diverse habitat mosaic of post-glacial Britain. It is then, I feel, that nature reserves would come into their own. They will have acted as refuges for all those habitat specialist species, which can then start to spread out, colonising the new gaps and niches in a rewilded landscape. If we lose them before then, to an ill-advised lack of management, when the time is right we may find that Noah’s ark is empty.

So there you have it; I wholeheartedly agree with Mr Monbiot’s aims and will continue to enjoy his writings, but I think in the case of ‘Feral’, to criticise traditional conservation is to pick on the wrong target. And until the day when he can guarantee me a place for the Small red damselfly in his brave new rewilded world, I will carry on doing what I do.

Tilting at Windmills


The recent outcry over the omission of the Green Party from pre-election debates prompted me to look more closely at the environmental policies of new-comers to the debating table, UKIP. It was rather like turning over a stone; the blind, wriggling creatures you discover are fascinating and repulsive in equal measure.

Take, for example, their attitude to trees. They are all for trees, are UKIP, which is great. They want to see England swathed in woodland once more, to the point of banning ‘the mass falling (sic) of trees in all forms’. Which is fine unless you want to manage one of those awkward non-woodland habitats, like heathland or chalk grassland. And what about coppicing?

And then there’s renewable energy. UKIP aren’t so keen on renewable energy. They hate wind farms, because ‘the rotating blades kill and maim countless of (sic) innocent birds…’ They also ‘emit grotesquely disturbing noise pollution which petrifies so many small animals’. The horror…

Solar farms are no better. Encouraged by the ‘obscene’ feed-in tariff incentive, they are effectively a ‘life sentence for the countryside’, scarring a landscape they describe as ‘the most breathtaking on mother Earth’ (clearly UKIP members don’t travel. Not ‘abroad’, anyway).

Whilst I love the British landscape dearly, even I admit that there are parts of it – the flat, agricultural lowlands, for instance – that can be a little, well, dull. There; I said it. But here I think the UKIP are mistaking green for Green. Vast rolling acres of high-intensity cereal agriculture may look verdant, especially if you spend most of your time in an urban environment, but in ecological terms they are close to deserts.

It's green. Green is good, right?
 Solar farms tend to be constructed on the poorest quality agricultural land; areas that require high (and therefore expensive) fertiliser input in order to scrape a financially viable crop from them. So leaving aside the point that we should be encouraging the use of solar power anyway, we are also talking about the conversion of land that is ecologically depauperate and requires a high input of agrichemicals into something that produces energy from sunlight. But the key point is that, with appropriate landscaping, such sites can become wildlife havens too.

The lack of disturbance and chemical input means that the area around solar panels is ideal for the sowing of low-maintenance seed mixes. In a landscape where nearly all the plant species remaining are wind-pollinated cereal crops, providing a long-flowering nectar source can have enormous benefits for pollinating insects.

A scar on the landscape?
FlowerScapes are excited to be working with the British Beekeepers’ Association and major solar energy providers Belectric on a number of sites across lowland England. These sites have been transformed from sterile green prairies into a blaze of nectar-rich colour. I’m sure UKIP will hate them, but the bees might disagree…

Ragwort - friend or foe?


Ragwort is a plant that provokes strong reactions amongst a certain group of people. We'll come back to that, though. First of all, ragwort is not a single, plant; it's a group of related species, all members of the genus Senecio. Common ragwort (Senecio jacobaea) is a widespread plant of grassland, meadows and road verges throughout Britain. Its close relatives - hoary ragwort, Oxford ragwort, marsh ragwort and fen ragwort - are less common but very similar in appearance.

Oxford ragwort is a non-native invasive species which was originally introduced to Britain from Sicily in the early 18th century. It found the clinker of railway tracks very similar to the volcanic slopes of its homeland, jumped the wall from Oxford University Botanic Garden and began to spread along railway lines. Fen ragwort, conversely, is native but extremely rare, being confined to a single ditch near Ely.

But let us return to the common ragwort and its problems. It has the unfortunate property of being poisonous to horses and other livestock, causing liver damage or death. Whilst they might avoid it as a living, green plant, once cut and dried as hay it becomes more likely to be ingested. This effect on the pampered mounts of the chattering classes has led to common ragwort being vilified and persecuted. It was listed on the 1959 Weeds Act (yes, there is a Weeds Act), which can require a landowner with ragwort on their property to take action to control it.

Which is a shame, because it's a really good pollinator plant. It flowers abundantly, it is visited by a wide range of insects, and it is even the host of a particular species of moth, the cinnabar, whose distinctive striped caterpillars are found nowhere else (I recently heard them referred to as ragworms, a word I am going to use from now on). And it really is only a problem where horses or other livestock are likely to graze. So let's leave the poor plant alone on road verges and waste ground, and long may it support its ragworms!

God's Acre


An area of land, open to the public, protected from development, with a long history of management as, usually, grassland with scattered trees. 
Nature reserve? No – churchyard!

Above shows one of the 7 lost cemeteries of  London, now no longer a working cemetery, but a local nature reserve, with grave stones overgrown with red valerian, giant squil, catchfly and ox-eye daisy.
 
St Wilfred's Church in Haywards Heath.
Many of our churchyards are havens for wildlife, having had the continuity of management that many nature reserves can only dream of. Many of them are incredibly old – ancient churchyard yew trees often pre-date the church itself, marking pre-Christian sites of worship – and they are often undisturbed, particularly if contemporary burials are taking place elsewhere. This long history of steady management means that species have time to colonise, and some churchyards support a high diversity of plants, insects and – on the gravestones – lichens.

Churchyards do suffer, however, from the blight that afflicts many public spaces – over-tidiness. Especially in areas that are still actively visited by relatives, there is an expectation to see the grass mown short and the weeds eliminated. And that is fine, but as is so often the case, there is almost always space for a little wildness.


In the old, unvisited corners of churchyards, many more enlightened churchwardens allow the vegetation to grow up in the summer, effectively managing it as a meadow. Sometimes they do this in the face of criticism from their parishioners, but surely – in God’s acre – there is room for all creatures great and small?
