Butterfly bushes in the Buzz series are much smaller than the standard butterfly bushes, growing only to 3 feet tall and wide. They are lovely selections for large containers, pairing nicely with other perennials and showing off fragrant blooms over a long period. 'Hot Raspberry' butterfly bush is also a lovely plant to tuck into a hot corner, such as near the driveway or garage. Dark pink blooms smell like warm honey. They will rebloom if of blossoms are pruned off.
