Hydrangea are some of the best flowering shrubs around. They're remarkably easy to grow and bloom reliably with great displays. However, because they're prevalent and mostly display showy blooms, they don't appeal to a lot of younger gardeners who associate them with their grandmother's garden. There are, though, a lot of Hydrangea choices that are much different from the "pink puff" style hydrangeas that many gardeners think of these days.
The Halo™ Hydrangea series is one of the best of these interesting Hydrangeas The flowers have lovely creamy color that is rare on shrubs, but it is the unique picotee edge that really sets these shrubs apart. My favorite of these is the Hydrangea Angel Song, which features a sharp pencil-thin white picotee.
