'Tennessee Waltz' is like a double form of 'Coquet Bell' in a way. They both have a very similar growth habit and they are very similar in coloration. Yes, the colors in the photo don't look as blue as 'Coquet Bell,' but that is because the flowers are more open. When the flowers on 'Coquet Bell' are more mature, they turn this color. 'Tennessee Waltz' is both a heat hardy and winter hardy upright fuchsia! Sources quote it as growing to two feet, but I am hoping for a larger bush since the winters are not as cold here as the area where this information came from.
