Wildflowers and other flowering plants

Below is a non-exhaustive list of some of the many flowers and shrubs to be found growing at Magog Down. Most of these articles include lovely descriptions and history about the plants, written for us over the years by plant pathologist David Yarham. Some articles have been updated recently with new photos of the plants thriving thanks to our Rangers' careful management.

We welcome visitors' photos to help enrich our website, so if you have any you'd like to submit, do send them along to photos 'at' Perhaps you've spotted a wildflower that is not yet featured here?

Thistles - Cirsium arvense and Cirsium vulgare

thistle1In the beginning, of course, it was all Adam's fault. One bite of that forbidden fruit and it was "Cursed is the ground for thy sake, ...thorns also and thistles shall it bring forth to thee..." and, ever since, thistles have been both a curse and cursed. As a boy I earned my first wages leading horses in Norfolk harvest fields and I still remember the comments when a sheaf containing "jagger-nettles" (as we called them) was pitched to the man on the wagon.

thistle2Of the two species of Cirsium found on the Down, it is the perennial creeping thistle (C. arvense) which is the farmer's worst enemy. Once introduced into a field it spreads by means of creeping lateral roots to form large dense patches which were extremely difficult to eradicate in the days before modern herbicides. The biennial spear thistle (C. vulgare) spreads only by seeds so tends to occur as isolated plants in a field.

But it was the Fruit of Knowledge of Good and Evil which Adam is supposed to have eaten and his descendants soon came to know that there is some good even in thistles. Thistle leaves crushed to break off the spines were once used to provide valuable fodder for cattle and horses, thistle seed are a favourite food of that delightful bird the goldfinch, the plants have been used in herbal medicine (Culpeper claimed that they would cure bad breath and B.O.!) and, of course, the rich purple, almost heraldic, flowers of the spear thistle have their own bold beauty.

In the summer look for the creeping thistles bearing the bright yellow pustules of the rust fungus Puccinia sauveolens. The rust gives the plants a somewhat sweet smell - the only plant pathogen that I know of which has such a pleasing property. Later the fungus produces dark pustules of resting spores and then the scent is lost.

And finally, for those who like bits of absolutely useless information, the head of a spear thistle dropped into milk will curdle it. Try it and see.
