Roses are my favorite flower. I developed a passion for them. And in my own garden, I didn't want to be fussing with just roses. I enjoyed other plants as well.
I think for homeowners, it is easy to break tradition and use them as garden plants.
Gardening is supposed to be all about trying. Don't plant and walk away. Maybe it doesn't work. Try something else, ... Don't expect the garden to be left on its own. ... It requires work. That is the fun.
