We just purchased 5 Tutti Frutti butterfly bushes from Ellis Home and Garden. We already had one of these that had been in our garden for a year, and we were totally pleased by its performance. Also, it has stayed evergreen, even though we did had temps in the low teens for a couple of days. According to the info tag, these are supposed to be hardy to -10/-20 degrees. Mature height is 2.5 feet and width to 3 feet and our bush has already achieved that. We also have a Petite Blue Heaven and it has the same growth habits as Tutti Frutti. We wanted to have smaller bushes to care for, and so far we really are enjoying these.
