The older I get (and the more perverse?), the more I appreciate these plants. The red one is 'Red Prince', one of the "usual suspects" at the garden center; they were only planted last year so they're really just babies. The middle plant with multicolored flowers, they darken as they age, is a favorite. The plants, there are more than one, in the bottom photo were renewal pruned last year and they did a darned good job of renewing themselves. Still, if you want to grow these older larger selections, you're going to need a good bit of property.
