|I'd highly recommend Endless Summer Hydrangea for your cold winter gardening region. This is the first Hydrangea macrophylla that blooms on both old and new wood, so it flowers virtually all season long and is hardy to zone 4. Endless Summer? will produce magnificent pink to grape to blue blooms depending on the pH of your soil. Alkaline - pH 6-7 will produce pink blooms. Acidic soil - pH 5-5.8 will produce blue ones. For blue add aluminum sulfate to the soil.
