|And whatever you do, don't plant bishop's weed, aka goutweed, often recommended for dry shade. Evil evil evil. It's like deliberately planting bindweed - you'll never have anything else. They were selling it at my local (reputable!) garden centre, at $10.99 a pot. Clearly they're Satan's little helpers.|
And there are plenty of blog posts out there like this one from Danger Garden talking about back breaking effort digging out this invasive pest.
Still, I think it's lovely and it seems just the right thing to put in the area of bare ground at the back of the house where I have my azaelas, heavenly bamboo and Pieris japonica. So I planted starts from my across the street neighbor last fall and have been delighted to see it coming up well this spring. I may later eat my words and regret this decision. But for now I'm saying one man's weed in another gardener's delight. Grow bishop weed - grow!
