Wayside flora on a summer's walk

This month, my wanderings have taken me up and down the Valley Trail, the site of the old railway line to Long Melford and beyond, and now a wonderful tree-lined track, free of motor vehicles and full of wild flora. The Sudbury Common Lands Charity volunteers manage this rural byway - keeping it accessible for people and creating gaps in the canopy for light to get through and encourage wildflowers to flourish. 

Burdock

In one woodside verge, I spy the spiky seed heads of greater burdock – those thistle-like balls that attach themselves to your clothing when you are out for a walk. As kids we loved to throw them at each other or furtively attach a few to the jumper of an unsuspecting passerby. It is a pastime that children down the ages have enjoyed and has led to nicknames for the burdock seed head, such as 'Sticky Jack' or 'Sticky Bobs'.

Some communities take the adhesion of burdock burrs to people to extremes. In Edinburgh, for example, the summer ritual of the Burry Man has been running for centuries. It involves someone being covered head-to-foot in the seed heads with only eyeholes and a mouth hole exposed. One account I read said it took two hours to cover a man in the burrs. Once suitably smothered, they are taken house to house – presumably in search of a sympathetic neighbour who might help them take a drink through a straw.

However, these hooked seed heads have evolved for other reasons than to enhance children’s games and maintain ancient costumes. The clever design enables the plant to disperse its seeds by attaching themselves to the fur of passing animals who will carry them to a new location.

Velcro

It’s all clever stuff, and an evolutionary adaption that, as the story goes, piqued the interest of Swiss engineer, Georges de Mestral – the inventor of the zip-free fastener Velcro.

Apparently, after a hunting trip in the Swiss Alps in the 1940s, de Mestral spent a long time removing the burdock burrs from his dog’s coat. Engineering curiosity got the better of him and before long he was examining the burrs under a microscope, discovering they had tiny hooks which allowed the seeds to catch on to things.

It’s a great example of biomimicry – nature inspiring industrial design – and De Mestral named his invention Velcro – a combination of the French words velours (velvet) and crochet (hook).

Harebells

On a nearby exposed, sunny mound I see a gathering of harebells, beautiful lilac summer blooms and one of UK’s most charming and delicate wildflowers.

One tale I’ve heard is that the name harebell comes from their tendency to grow where hares are seen – and it’s true in this instance for these are near my favourite hare-watching spot. I’ve also heard them called 'witches' thimbles' because in olden times it was believed that witches were able to turn themselves into hares.

Stroll along the Valley Trail at thsi time of year and you area bounfd to encounter plenty of wild flowers.

Common Toadflax

In the same spot stands a cluster of common toadflax, a widespread wildflower, also known as ‘butter and eggs’ due to their yellowy colouring.

I’ve read the name Toadflax originates from the resemblance of the mouth of the flower to the wide mouth of a toad. These flowers resemble snapdragons and for some smaller insect pollinators this mouth can be difficult to penetrate, but the larger bumblebees are strong enough to get their tongues deep inside the throats of flowers and get to the nectar.

Moths are also attracted to the flower including the aptly named toadflax pug moth – a beautiful black and brown moth who’s caterpillars feed on the flowers and seed pods.
