I love balloon flowers! This is a very nice one, that unlike others, doesn't seem to seed itself. Blooms July-September in my garden.

This is a very pretty flowering plant that is also well behaved. It may be my imagination (or my aggravating memory), but it seems over 3 years to have reappeared less "blue" than Tilly was when I bought it. I first appeared as a startlingly blue violet color, now it's a nice, clear blue. Lovely with Johnson's Blue geranium.
