And it's deadly, and has been thought of as being used in the "white slave trade" once upon a time to induce a languorous state in which no action could be taken against rape. It seems to have spread around the world a lot for no apparent reason. I gather it was first met at Jamestown? So what it was doing in the Warren at Folkestone, a wild area, where it was rumoured to be in my youth is a bit hard to understand. Some grew in an area once used by a London park for garden waste a few years back. Right next to the play area. I looked it up on the Royal Horticultural Society's site, and nobody does cultivate it. However, it does pop up regularly having been spread in birdseed. ? Got any stoned birds around? And I've heard the same yarn about hemp. Rather more believably, but still... They advise using gloves, and that normal composting will deal with the plant, decomposing the alkaloids, while the council's garden waste system will deal with unripe seed heads. Ripe ones should be burned, and under no account should the seeds be allowed to spread. As soon as my friend's photographed it, it's off.
