These fluffy, fern-ish leaved perennials have been in my yard for years but I'm still not quite sure what they are. I've never seen it flower, though it's growing in the shade so perhaps that's why.
Super, thanks! Apparently tansy likes full sun so that must be why I don't get those cute button flowers I see in online pics. It's a fast spreader, but not so for me, having it in the shade, so it looks like I'll be keeping it there in the shade.
