Teresa,
Buzz series butterfly bushes grow 3 - 5 ft tall and wide and are bushy. They were bred especially for smaller gardens by Thompson and Morgan in the U.K. I have 'Sky Blue' (which I love) and 'Ivory' (which I don't). 'Sky Blue' attracts enormous numbers of butterflies and is beautiful, with an abundance of flowers all summer until frost and a bushy, well branched growth pattern. 'Ivory' has a dirty white appearance, from my perspective, and the butterflies ignore it.
My only previous experience with butterfly bushes was with the very tall, fast-growing, out-of-control type that took over the gaden. I gave that one away (along with appropriate warnings, of course).
