Ragwort gets a bad rap for being poisonous to horses, which it is, but that’s hardly the fault of the wildflower, and rather more of a system that manages to package it up in feed for domesticated beasts…Read more

You can be a long way into a game before you even realise that’s where you are. Who defines the field of play, the value of each piece, the manner in which one element should engage with the others? You might wonder what the Cinderella syndrome could possibly have to do with gardening, but consider how we designate certain plants as weeds, and all should become clear.Read more
May brought us sunshine and rain, burgeoning borders, a late frost and, of course, the RHS Chelsea Flower Show. It’s the month of the gardening calendar when everything goes a bit bonkers – in a wonderful, exuberant way. Always quite nice to reach the end with your sanity intact, and your body parts functioning, though by the final week I was being reminded of the need of a good stretch, and that its about time I really ought to be getting some serious yoga practice in.Read more
Autumn turns to winter, the leaves are all but tamed, and a short window of opportunity opens. While it’s still warm enough feel your fingers, there’s just time to clear the beds in preparation for a good, thick mulch. But what to do with all the stuff this produces – compost, or burn? It helps to have a plan.Read more
Not long now till many of our trees, shrubs and perennials divest themselves of their foliage before swooning into a hibernal slumber. Meanwhile, less glamourous things – semi-evergreen, hardy biennial and annual things – are quietly going about their business, apparently unfazed by the drama, while we pass them by..Read more
While most people will stroll along the borders marvelling at fabulous specimens, I spend half my time peering at the lawn or at cracks in the paving to see what's taken root of its own accord. It’s in exactly this kind of situation where I’m likely to encounter birdsfoot trefoil, a plant which the Victorians, for reasons best known to themselves, associated with dark feelings of revenge.Read more
Depending upon your perspective, May is a great month either for wildflowers, or for weeds. However you choose to view the often statuesque plants that appear fully grown almost overnight in our hedgerows and gardens, their presence is hard to ignore, and their fresh, frothy and voluminous presence provides a welcome space filler after the drabness of winter.Read more
The admission causes me a degree of discomfort, having on numerous occasions made my admiration for weeds a matter of record, but even I find it hard to wax lyrical about hairy bittercress.
It’s also something of a gremlin in the garden, and you need be in no doubt that you will have hairy bittercress in your garden. Possibly also its cousin, wavy bittercress (Cardamine flexuosa) – very similar in appearance, though the small white flowers have six stamens to the four of its nominally more hirsute relative (the hairs on the leaf margins and axils aren’t particularly noteworthy, in spite of the name). As long as extremes are avoided, bittercress can’t bring itself to be discerning over the pH of the soil, seeming just as at home in acid, neutral or alkaline conditions, and will grow in shade, part shade or sun, in either moist or dry conditions. A hardy annual (C. flexuosa sometimes persisting as a short-lived perennial) it behaves as an ephemeral weed, producing several generations in one growing season, and each plant can produce up to 5,000 seeds.
|Not wavy, but downy. Four stamens, so Cardamine hirsuta|

As fond of weeds and wildflowers as I am, it wasn’t without a wry smile that I acknowledged the arrival of this plant in a bed from which I’d only recently been congratulating myself for liberating from ground elder.
Circaea lutetiana, or enchanter’s nightshade, has a similar creeping habit to that carrot which fills some gardeners with horror, but which I’ve always found myself able to tolerate, as long as it doesn’t object to a triple whammy of vigorous forking and pulling out, and a good strimming of its aerial parts when the urge comes upon me.
The botanical name possessing twice the magical power of the common (Circe being the sorceress of Homer’s Odyssey, and Lutetia referencing an old Latin name for Paris, the ‘Witch City’), Circaea isn’t part of the nightshade family (Solanaceae) at all, but rather a relative of willowherbs and the evening primrose (Onagraceae). It’s generally described as being “not particularly toxic”, so you probably won’t want to be dashing out to gather it up by the armful for pesto. As a plant of woodland glades and edges, it revels in slightly damp, light shade, and can establish large colonies if allowed to grow unchecked, in which situations it might reach its full height of around 60 centimetres, though I’ve rarely encountered it in a garden at more than a third of that size. While its underground rhizomes will take it only so far, its hairy oval seed capsules facilitate any designs it might have on wider conquest; towards the end of summer, it’s not uncommon for the dog owner to find several in the coat of their furry friend.
Although it’s not tiresome to pull out, it’s probably not something the gardener would want to encourage, unless in a woodland setting. That said, when in flower, I find it rather pretty – above the spear-shaped, opposite green leaves a spire-like raceme, rather openly (some might say ungenerously) populated with tiny flowers (reminiscent of some of the less abundantly-floriferous heucheras). The flowers themselves are white, sometimes with a pink tinge, and have two, deeply divided petals.
A large patch of the stuff in your borders is probably not be what you want, then. But if you should catch the odd plant out of the corner of your eye, flowering daintily away in some forgotten leaf litter under a large shrub, you might want to leave it be. Noone likes to run the risk of upsetting an enchantress.
