I took the last of the spray paint and primer that I had been using in our previous house to repaint the toilet seat, and used it to paint a dead bush in the yard.
The paint makes the bush look silver, not white. It's in a very dry part of the yard, so if we replaced it with something living, we would have to water it frequently.
In other news, I added a possible correction to the second post before this one, here. There is a lot that we still don't know.
