I like to think of these as "wild chimneys," ones that grow randomly in nature. Some can even be harvested for use as actual domestic dwelling chimneys, but I think they should remain free and wild.
Vewy pwetty fwowers. :) I wanted to wait until the last pic to comment, otherwise I'd be sitting here all afternoon. :) Uh, does your mom like roses? ;) Jk. I loved the dark burgundy ones on the brick side of the house.
