ENDLESS SUMMER HYDRANGEA
These are wonderful because they bloom profusely on new wood and old wood . It used to be that the Nikko blue hydrangeas only bloomed on old wood , so you had to prune them at the exact right time or risk having no blooms at all . These showstoppers are a must-have for most gardens in the US with a hardiness rating of zones 4 – 9 . Not sure which zone you are in ? Check the Plant Hardiness Zone Map on page 26 .
