Here is the biggest bumblarium in the world, shown at its inaugural outing at the Gardener’s World Show at the NEC. I borrowed the idea from those nice folk at Wildflower Turf, whose lovely product (sold by us!) the bumblarium features. They put me in touch with Robin Dean of Red Beehive who had made a version for them which was hugely successful at the Ecobuild Show. Robin knocked up this one for us, and it was brilliant in attracting people to the stand we shared with the Bumblebee Conservation Trust.
The bumblarium is like a vivarium for bumblebees, with a little colony of Bombus terrestris spp. audax (Buff-tailed bumblebees) and a wildflower meadow floor for them to play in. It excited a fair amount of interest and the cost and palaver of putting it up was further justified by getting a “Highly Commended” for it. The wildflower turf looked brilliant. The diversity of species in it – over 25 – meant we could have a competition asking people to name five of them. So what did we learn?
Oldies know their wildflowers much better than the young, but that’s not saying much! One lady asked me to identify the plant taking over her front garden as she hadn’t seen it before and she wondered if it was something so rare she should leave it. She’d even brought a cutting along to show me. Creeping Buttercup.
Many gardeners have a “wild section” in their garden which they leave untended. All well and dandy, but I did wonder how much more helpful a regime of relaxed management might be for bees. Dock and nettle aren’t renowned for their qualities as bee plants.
Another oddity which keeps coming up is the way people buy wildflower seeds and sow them. Even careful gardeners, who might spend hours at a horticultural show finding exactly the cultivar they wanted, cheerfully buy an unidentified packet of wildflower seed and just fling it on the lawn. They’re then disappointed when it doesn’t work – perhaps it’s just as well! I kept on suggesting people look at our how to make a wildflower meadow area video.
My longer term worry about wildflowers is the way they are becoming exclusively identified with a particular look – i.e. hay meadow – and that people aren’t using them in combination with cultivars in more formal schemes. If I had a small urban garden I’m not sure I’d have a meadow area myself, to be honest.
Most people are profoundly in the dark about different types of bees. We spent ages explaining the differences between bumblebees, solitary bees and honeybees.
The Tree Bee, a recent arrival from France, is turning into something of a nuisance. A lot of people had problems with them taking over nestboxes, and their behaviour and predilection for raised nest sites means they’re not just obvious but also more likely to be annoying.
I was saddened to meet people who had bought bumblebees off the internet to put in their gardens. There’s a lively trade in bumblebee colonies to pollinate fruit in greenhouses – it’s how we got our bumblarium bees – but to buy them at vast expense for your own garden seems very peculiar, quite apart from any bio-hazard they may bring. Plant the right plants and they will come.
