Talkback: Valerian

I actually grey this deliberately for the butterflies, of which there are, sadly, too few. My personal view is that anything that encourages bees or butterflies should not be thought of as a weed unless its really horrid, thick Japanese knotweedish sort of things.
I'd be interested to see what people think about this.

Totally agree. Anything that benefits insects, butterflies or birds stays, if it spreads it's up to me to keep it in check but it still stays.
