Knotweed: The naughty and the not

To be honest, most knotweeds are at least a little naughty. They can spreaaaaaaad. That might be a good trait in a ground cover. But some, notably the invasive and hard to eradicate Japanese knotweed (Reynoutria japonica, syn. Fallopia japonica, syn. Polygonum cuspidatum), are very, very naughty indeed. This PDF from the Ontario Invasive Plant Council explains. Others, like our covergirl, Persicaria amplexicaulis […]

Invaders I wish I’d never planted

This is not a picture of a spring garden. No, it’s a stand-off between the Hatfields and McCoys, with Prokofiev’s ominous Dance of the Knights as the sound-track.

Love/Hate, maple-flavoured

Meet the bane of my existence right now: a forest of Norway maple seedlings. The conditions must have been so right for maple seed germination this year. In all my years gardening under Norway maples (Acer platanoides), I’ve never seen such an abundance. A veritable pro-leaferation! If they were worth money, I’d be a gazillionaire. […]
