July 12th – One indicator of an advancing summer I always have mixed feelings about is buddleia. This purple-flowering, profuse shrub, sometimes known as the butterfly bush is great for bugs and bees and lepidoptera of all kinds – but the one issue I have is it’s the shrub of urban decay.

This versatile plant will grow anywhere it can find – gutters, chimneys, soot-filled fissures in brickwork, and once it takes hold it will destroy masonry as it grows. It’s the sign of dereliction in summer, growing old disused rail lines, factory yards and edgelands of all types.

A fascinating, but destructive plant.

July 3rd – It’s time for my annual heart-wrenching over the purple conundrum that is the butterfly bush. Buddleia is a prolific, very common shrub that will grow anywhere, in any scrap of earth or soot, and is synonymous with urban decay: look upwards in any town right now and you’ll see this tenacious battler growing and flowering from cracks in brickwork, lifting tiles on roofs, blocking gutters, prizing apart chimneys and crowding any embankment, towpath, disused rail line or wasteground.

It’s beautiful and very good not just for Lepidoptera, but all manner of bugs and is very, very pretty. But it is such a symbol of dereliction and decay.

July 20th – People seem to think I’m negative about buddleia, but I’m not really. It’s a beautiful purple shrub that lights up late summer wonderfully, and it’s not known as the butterfly bush for nothing – the Lepidoptera love the huge flowerhead composed of tiny, individual blooms. 

My problem with this plant – if it’s a problem at all – is that for me, it’s a harbinger of urban decay. It’s so successful in urban environments that it’ll grow well in a patch of soot in vertical brickwork. At this time of year, throughout the urban expanses of the UK you can see buddleia sprouting and flowering from derelict buildings, bridges and rail lines. Seemingly one of the first signs that nobody cares for a place anymore is that it starts flowering in purple at high summer.

You can’t blame the plant for that… 

August 17th – Between Darlaston and Pleck on the Walsall Canal, near James Bridge, the old turnover bridge for the defunct Anson Branch. It’s just as well the line is truncated now, as that huge pipe renders the turnover aspect of the crossing pointless. 

It’s fascinating to see the bracken, buddleia and other weeds gradually dismantling the blue bricks. Gentle, oh so gentle hydraulic pressure gradually and steadily cleaving mortar from brick, using any crack or fissure where a scrap of nourishment can be found.

Nature is remarkable in it’s determination.

June 29th – Passing through New Street Station early on a sunny, bright morning. The skyline looked as busy as ever with clashing architectures, wires, antenna and other urban structures. And in the middle, the buddleia growing from the signalling cable raceway on the Hill Street Bridge was flourishing, seemingly unhindered and unnoticed.

July 20th – A very dull day, and I was caught in the rain twice. Still, the rain was warm and the atmosphere hot and humid so it was quite pleasant when I was;t riding into it.

I notice in the last few weeks the buddleia has burst into flower. Known as the butterfly busy, the copious purple blooms are a boon for lepidoptera and other bugs, but due to the remarkable tenacity of the shrub, I’ll always view it as a the  harbinger of urban decay. Wherever there is dereliction, neglect or abandonment, Buddleia takes a hold, be it disused factories, rail lines or in issues in masonry. As it grows, it will pull brickwork apart and swamp all beneath it.

A remarkable plant.

January 6th – I’d not noticed this before. On the canal near Darlaston, a high factory wall, and by some twist of nature, soot and the wind, a pair of buddleia plants, slowly and tenaciously taking the brickwork part by the action of gentle and sustained hydraulic pressure alone.

Although it’s destructive, I love to see this; nature reclaiming the constructed. It’s nice to see nature winning occasionally.

July 22nd – The Mad Old Baggage noted the other day that buddleia was known as the ‘butterfly bush’ – and she’s right. By a busy roadside in Walsall, the purple, masonry-destroying shrub is quietly reclaiming the built, and using it to nurture the lepidoptera.

It may be a plant of the margins, scrubs and wastes, but buddleia is a bright, beautiful shrub that clearly supports a whole host of bugs – which can’t be bad.

A fantastic sight.

July 6th – I wasn’t in the mood to ride much – I had lots of work to do, so just popped up to Chasewater to check out the Craft & Farmers market, which again, disappointed. I shan’t bother with that again.

I spun out for a circuit around the park, and was taken by the buddleia, water lilies and various marsh orchids, which out here, unlike the ones near the canal, hadn’t gone over yet.

I stated last week that the flowering time was passing; but I was wrong. Things are still flowering well, just in different ways and different places.

This really is a most excellent summer.

July 2nd – The onward march of summer means more purples – the urban wasteland warriors that are willowherb and buddleia come into bloom around now. This willowherb – or old man’s beard – is growing well at Telford Station near the overpass, and is a welcome splash of colour in an otherwise dull patch of scrub.

After flowering, this tall, distinctive and very common wasteland plant forms wind-borne seeds that will drift on the breeze and fill the station with white fluff.

Good for birds and butterflies, both plants grow well in urban areas and spots either beyond the reach of man, or out of his sight. They are a testament to the tenacity of nature.
