One of my favorites and so easy a child can plant them. These flowers hit their stride right about now and the newer varieties offer lots more than one big messy droopy head twelve feet up in the air. Although I kind of like those, too. Another one the kids can plant all by themselves. Rose of Sharon .
Colors range from a glaring bright white to an almost blue through the gamut of pinks and purples.
Plant it where you can see it from your favorite chair. Don't let it go to seed unless you'd like some everywhere. Awesome is one way to describe the display, especially if you hate the color. You need this excellent tall white in your perennial garden. I think I like it best teamed with the restful backdrop of ornamental grasses.
