February Gold and a Fool's Spring

View fullsize

With the synthetic cheer of the twinkling fairy lights of Christmas in the dim and distant past, the long dark trek to springtime always feels like a brutally hard slog.

The ground seems stark, barren and lifeless. Yet all the while beneath the surface plants and trees are quietly, imperceptibly getting ready to burst out from their winter buds.

Catkins, male flowers of many common native shrubs and trees such as Hazel (Corylus avellana) and Birch trees (Betula pendula) are among the earliest augurs of that yearned for spring. As the days rapidly lengthen, golden evenings start to appear, bathing the delicate, golden chains of late winter catkins in beautiful light.

In contrast to the deep chill and bitter Beast from the East last year, winter 2019 has been remarkably mild. This February has even proven to be the warmest one on record thanks to a brief flurry of sunny mild days that heartened us all with a tantalising promise, however fleeting, of warmer days to come. One mild evening in mid-February I took advantage of the rich late afternoon light during our "fool's spring" to do a little study of the Hazel and Birch tree catkins in my garden.

I learned that branches carry both male and female flowers with the male catkins emerging first. Hazel trees carry tiny little female red flowers that emerge soon after higher up the branch stem, whereas Birch trees have small, bright green, upward curving female catkins.

Catkin pollen is intended to be windborne to pollinate other trees, there being so few insect pollinators about at the time of year, so it has evolved to have a self-repelling quality meaning that bees and other insects struggle to collect much of it, although it is a food source for them at a time of scarcity.

Despite the luscious hue of light, the days rapidly turned back to chilly ones with even our fool’s spring warmth quickly forgotten. But soon, soon true Spring will burst forth in her lush green finery and the late winter gold fade out of memory.

The Beast from the East

Winter definitely had a vicious sting in its tail this February. A "sudden stratospheric warming" over the North Pole, in itself disturbing at this time of year according to climatologists, caused a sharp cooling in lower levels of our atmosphere and via a complex chain of meteorological events reminiscent of the metaphor about the butterfly that flapped its wings on one continent and caused a hurricane on another, brought about heavy snowfall that covered virtually all of the British Isles.

An unusually strong and harsh northeasterly wind stream dubbed the "Beast from the East" triggered a bitter cold snap then swept in heavy snowfall, which was in turn intensified by strong drifting due to the fierce, biting winds that blew continuously for days. 

Here in big sky Norfolk we were heavily exposed to "the Beast" and much of the county was cut off by incredibly large snowdrifts formed by its winds. These, I noticed, were far deeper in areas where the farmers' field verges lacked hedging, a stark reminder of the environmental value of this oft overlooked habitat, which for many years was ripped out to maximise the yield potential of the land in ill-conceived agricultural efficiency drives.

Thankfully many incentives now exist for re-establishment of these vital wildlife corridors and natural windbreaks, so hopefully Norfolk will improve its reputation among hedge layers in years to come.

Frost covered leaf litter

December has been colder than in recent times and we've had not a few chilly, white-world frosty mornings of late.

Hoar frosts have always held a special place in my heart as they always take me right back to fond memories of frozen winter wonderland walks up on the Ridgeway back in Letcombe Regis, but what makes a Hoar frost so special?

A Hoar frost, also known as hoarfrost, pruina or radiation frost, occurs on cold, clear nights with humid air when a dew would form if it were warmer.

In a Hoar frost, leaves, grass, branches and other objects cool by radiation to well below frost point, allowing water vapour to condense directly in the form of ice crystal deposits rather than in the form of water droplets first.

A normal White frost or Ground frost is caused when water vapour from the air forms a liquid dew first and then freezes with a subsequent drop in temperature, so tends to be more globluar in shape rather than feathery or crystalline. Fog tends to inhibit Hoar frosts as it prevents radiation cooling, however can create Rime, which is an ice deposit formed from supercooled fog vapour that crystallised when it touches a frozen object.

In The Bleak Midwinter....

Its January, normally the time of Jack Frost and blankets of white, mittens and snowballs...well not tis year!

El Nino seems to have put paid to all that white stuff in East Anglia for 2016 , which could be one of the warmest (not to mention wettest and windiest!) on record in the UK. 

The mild weather also has our plantlife well and truly fooled, with primroses and daffodils nodding alongside snowdrops and aconites. So, instead of a classic snowy winter's scene, this January's blog is of a winter's walk amongst the silver birch catkins at Narborough.

Signs of Spring

At last...the first days when you can feel the warmth of the sun on your back... aconites and snowdrops in full bloom... realising sunset is well past 5 o'clock...it must mean spring is on its way. These photos of pretty snowdrops and winter aconites were taken on a recent snowdrop walk on Lexham Estate in aid of their ancient church.

January's photo marks a return to home ground, both in genre and location. This frosted winter blossom image was taken in Nar Cottage's garden and is of one of our new winter cherry trees  "prunus x subhirtella autumnalis, planted to help winter insects, and it certainly seems to be flourishing even in its first year of growth. 

Frost Ferns

My first photo of 2015 was a reminder that you can discover beauty in the most mundane of places. This is a photo taken one morning of my bedroom skylight that slants southwards just as the sun just started to hit it with a peachy golden glow after a cold and deeply frosty night. I have cropped to tidy the composition and stretched the tonal contrast just a little to convey the depth and contours of the ice crystals but everything else is simply as nature intended....

Sun mist and rain

January has been an odd mixture of golden sunrises and vivid sunsets with heavy overnight rainstorms, though here in East Anglia we’ve escaped lightly compared to the western half of England that faces the onslaught of the sou’westerly Atlantic storms. Here are three of my photos taken in the month attempting to capture these contrasting elements of winter in Norfolk.

Winter Aconite, Eranthis Hyemalis Peeping Through Snow

Even though we have had thick snow on the ground for a week and a half now there are still faint augurs of spring all around us if you look hard enough. And the sight of this bright yellow Winter Aconite, Eranthis Hyemalis amidst the snow brought me joy.

Gardening Value of Winter Aconite

This delicate, yet plucky little flower is one of the very first plants to flower in the new year; peeking its cheery buttercup-like head bravely out even when it has to tunnel through thick snow to do so, often while the more famously celebrated Snowdrops are still little timid shoots barely starting to make an appearance. As well as resembling a Buttercup, Winter Aconites are also related to them being in the Ranunculaceae or Buttercup family.

Winiter Aconites are very versatile adding bright, vibrant colour and interest in the wildllife garden at a barren time. They can work well both in an informal wooodland edge setting, along a hedge or more formally lining a border or pathway. It is very effective for winter ground cover and tubours spread quickly in a carpet-like fashion, not unlike Snowdrops. Aconites will thrive in part or full sun in fertile, moist, humus-rich soil.

Wildlife Value of Winter Aconite

Being such a seasonal pioneer, its early flowering habit makes Winter Aconite a blessing for wildlife, providing an invaluable nectar source for early foraging bees, flies, beetles and other insects, with its cup-shaped flowers affording easy access. It’s a must-have plant in any wildlife garden. As with all Ranunculaceae Winter Aconites are toxic plants to mammals and so resistant to grazing by herbivores such as Rabbits or Deer or Field Mice.

Plant Folklore of Winter Aconite

Eranthis Hyemals is a non-native perennial, originating in Southern Europe and the Balkans. It was first introduced in the 16th Century (1596), became fashionable in 18th century landscape gardens including those of Lancelot “Capability brown”. This encouraged naturalisation, with it first being recorded in the wild in 1838. Winter Aconites can be found in many parks and woodlands across England particularly South of the Midlands and in the East of England.

Early herbalist John Gerard listed the Winter Aconite as "Winter Wolfes-bane or Small Yellow Wolfes-bane” in his 1636 “Herbal, Historie of Plants” and incorrectly placed it in the Aconitum family within Ranunculaceae, which includes Wolfsbane, Aconitum napellus. He described Winter Aconite thus: “whole leaves come forth of the ground in the dead time of winter, many times bearing the snow on the heads of his leaves and flowers, yet the colder the weather is, and the deeper that the snow is, the fairer and larger is the flower”.

He also remarked upon its peculiar claimed virtue of sedating scorpions “it is reported to prevail mightily against the bitings of Scorpions, and is of such force, that if the Scorpion passes by where it groweth and touch the same, presently he becommcth dull, heavy,and (de)fence!ess”. English playwright Ben Jonson (1572-1637), also alluded to this alleged trait in his tragedy Sejanus in 1603, which includes the lines: “I have heard that Aconite / Being timely taken hath a healing might / Against the scorpion's stroke.” however this may stem from Winter Aconite’s early incorrect classification as a “true” Aconite and confusion with the deadly poisonous Wolfsbane, Aconitum napellus. Who knows, perhaps that is what Gerard took as his source!

Winter Aconite’s scientific name, Eranthis hyemalis, was establied by Salisbury in 1807 and stems from the Greek “er”, meaning ‘spring’ and “anthos”, flower added to hyemalis, the latin for ‘winter-flowering’. However its common name “Winter Aconite”, still refers back to the similarity of its leaf shape to plants in the Aconitum genus, this being the feature mostly used to classify plants before scientific methods were introduced.

Local folklore names for Winter Aconite include “Christmas-rose” (Somerset) and “New-year’s Gift” (Essex) for its seasonal timing, “Choirboys” (Essex) alluding to the foliage “collar” surrounding its flower-head. Also “Devi’s-wort” (Somerset) perhaps due to its poisonous nature.

For me, the little Winter Aconite is a symbol of hope and cheer when everything around is still bleak and harsh and, for that, I love it all the more.
