These things grow like weeds, they kind of are weeds but useful to fill space quickly. Easy maintenance you do nothing lol. They grow everywhere so you get them for free. Kind of lame but my sheds look a lot nicer during the summer with these growing around them.
Toro is not going to like the way this thread is heading, but that's what he gets for trying to turn the gardening forum into something else.
Around here, which has always been rural but has slowly been losing even that population for a hundred years or more, there are plenty of places where there's nothing but scrub or empty fields and suddenly you'll see a bunch of day lilies or a cluster of old lilac bushes and maybe an ancient tree and there you will find an old cellar hole where the house used to be, and maybe behind that a handful of graves where the family buried their dead.
Day lilies and lilacs and antique tea roses are a sure indication that there was once a farm and a farm woman who prettied it up with flowers that have kept on surviving for longer than she, or her house--for over a hundred years, at times. It was how I found my great great grandfather's farmsite--from the tea rose bushes that are still growing on his grave at the cemetery. There is only one place in the area where those roses are growing now and there is a huge hedge of them. I went to the land records, and sure enough. So I knocked on the door of the house there, and they showed me where the farm house used to be.
These naturalized (not wild) flowers are amazing.
