The most compact reblooming hydrangea! Because of their ability to flower on new wood, most reblooming hydrangeas reach relatively large sizes. Let's Dance® Blue Jangles® hydrangea is the first compact rebloomer, maintaining a tight, neat habit while still forming dozens of flowers on new and old wood. Large mophead flowers turn blue readily under appropriate conditions. This Hydrangea grows in zones 5-9 and is 1-2' tall and 2-3' wide.
