The yellow is not clean. Each head is uneven — some petals longer, some shortened, some missing altogether — and a single plant carries the whole of summer at once: buds still held tight, heads fully open, and others already dulling, beginning to collapse. This is *Jacobaea vulgaris*, the common ragwort, come into bloom as the oilseed rape fades from the fields. It has a poisoner's reputation, a soldier's name, and one of the most generous flower heads on the verge — all three at once, which is the whole of the interest. ## The head that isn't a flower Look closely and the flower is not a flower. Each yellow head is a crowd: a packed centre of tiny tubular florets, every one complete with its own stamens, every one pushing its pollen up to the surface, so the whole face of the head carries it, floret to floret. The strap-shaped petals around the rim — the part you would call the flower — are florets too, turned outward like a ring of small flags. It is less a bloom than a table, and it is laid flat and open for anyone. > It is less a bloom than a table, and it is laid flat and open for anyone. And everyone comes. Hoverflies settle on the surface and feed without ceremony. Small solitary bees work it over without having to force or burrow into anything — the pollen is simply there, at the top, waiting. Beetles blunder through and brush a dozen florets at a step. A flower built like a closed bell makes its visitors earn the nectar; ragwort asks nothing, and so it feeds everything. Lower down, out of the light, aphids tap the stems for sap and ants tend them for the sugar they leak — a second economy beneath the first. For a plant with such a bad name, it keeps the best table on the verge. There are insects in Britain that eat from nothing else. ## The poison it hands on There is a price written through it. Every part of the plant carries pyrrolizidine alkaloids, and the threat in them is quiet and slow. Eaten, they do their harm by being dealt with: the liver takes them in and turns them, by its own chemistry, into something that kills the cells doing the work. No single mouthful announces itself. The damage simply gathers, dose on dose, and it does not heal. Most grazing animals taste the bitterness and learn to leave it standing. The cinnabar moth does the opposite. Its caterpillars — ringed hard in black and gold, daring anything to mistake them — strip the leaves and keep the poison down, carrying the alkaloids up into the adult moth and wearing them as armour. What would ruin a horse's liver makes the caterpillar the one thing on the plant that nothing will touch. The ragwort's defence does not stop at the ragwort. It is handed on. ## What the drying hides The real danger was never in the field. A horse with the run of a pasture walks past ragwort — the living plant is bitter, and the bitterness is a warning it can read. The danger is in the bale. Cut into an unwatched hay crop and dried, the ragwort loses its colour, its shape, and the bitterness that gave it away. It settles into the forage looking and tasting like the rest of it. The horse, this time, has no warning, and eats what it would never have touched alive. The plant has changed its appearance. It has not changed its chemistry. And the liver, quiet dose after quiet dose, keeps the count. ## Stinking Willie It earned a darker name than most. In the north of Britain the ragwort is Stinking Willie, and the name is said to carry more than the smell. After Culloden, in 1746, it was put about that the plant sprang up wherever William, Duke of Cumberland, had taken his army — Butcher Cumberland, whom his own supporters in the south had taken to calling Sweet William. The Scots, who had their reasons, turned the flower over: not Sweet William but Stinking Willie, the weed that came up behind the killing. Whether his horses' fodder truly carried the seed hardly matters now. The name held because the feeling was true. Elsewhere the names are blunter, and only about the smell — stinking nanny, stinking ninny, mare's fart. The plant announced itself, loudly and badly, in every dialect it grew in. None of which it minds. The ragwort holds its uneven heads out over the verge whether you stop for it or curse it — feeding half the insects of the hedgerow, poisoning the horse that meets it in the bale, carrying a beaten army's name down two and a half centuries without a word of apology. John Clare gave it a poem all the same: he loved to watch it litter the commons with gold, the same commons the enclosures were grubbing out, and never once asked it to be tidy. It will be on the next verge you pass — taller than the grass, the yellow not quite clean. Steadfast, belligerent and still quintessentially British. --- Source: The Britographer — https://www.thebritographer.co.uk/pages/ragwort.html.
