And here are some photos that show what those irises looked like before he dug them out. I took this photo on the left last spring when the irises were in bloom.
If it's hard to tell that there is a path under the irises, well... that was the point. To the right, in a photo from June, the irises are in the lower left corner, and there's the yard and the just-planted vegetable garden in the distance.
In the photo on the right, it looks like the irises are trying to sneak up on Walt, who has his back turned to them.
After all the invading irises were pulled out, I sorted through them all, cut off the long leaves, and replanted them in a small plot of soil behind the garden shed, next to my plum tree. "Replanted" is kind of an exaggeration, since the iris rhizomes like to be right on the surface of the soil, and they spread by "creeping."
We hope the irises will take root in that new spot and fill in against the wire fence. Only time will tell. Right now, I think they look appropriately creepy.
