Foxglove

This is a foxglove. I believe it is the Common Foxglove, digitalis purpurea (which sounds like some kind of hideous rash you might get on your hands.. but no matter). It's an interesting name and one apparently widely open to debate, but according to some 19th Century book of botany quoted on Wikipedia: "In south of Scotland it is called 'bloody fingers', more northward, 'deadman's bells'", which seem like unnecessarily gruesome names for what is quite a pretty plant. Probably this comes from the fact that it's extremely poisonous, as the leaves, flowers and seeds all contain digitoxin. Digitoxin has been used as a treatment for heart failure, as pioneered by William Withering (fabulous name for a botanist).

Withering also recommended it for the treatment of dropsy, a hilarious-sounding old fashioned disease which, I've just discovered, was an archaic name for oedema (Edema, if you're American. Or just can't spell). I always feel faintly guilty when I find the names for medical conditions funny. Like botulism. I don't know why, but the name just amuses me, whereas I suspect the actual condition itself would very definitely not...
