weeds that you keep
Some weeds are pretty. I guess they are actually wildflowers and if you keep them, they aren't really weeds. (A weed can be any plant you don't want in that spot, right?).
Which ones do you keep? The first time I came across Virginia buttonweed I thought it was a pretty groundcover but once I figured it can take over and as I read more about it, I now pull it out. I do keep the wild violets but pull some of them that are going out of bounds. There are a couple viney weeds that look sort of like wandering jew, and I keep them becoz they look good and don't get invasive.
Having cottage gardens makes it easy to keep some weeds, do you?
