I was treated to a new color combination this summer, and it quickly became my favorite. I’ve repeatedly raved about Geranium ‘Rozanne’ which grows 20 inches tall and blooms all summer into fall. I grow several of the plants and one them popped up through the raspberry-red plums of neighboring Astilbe ‘Rhythm and Blues’, and the results were gorgeous.
‘Rhythm and Blues’ grows 25 inches tall. Like most astilbes it blooms for about four to six weeks each summer while Geranium ‘Rozanne’ continues to flower until the first killing frost.
