Hydrangea arborescens Invincible Mini Mauvette®
Finally a super hardy Hydrangea for Siberian winter gardeners!! Deciduous, compact shrub 30-36” round; strong, no flop stems feature pink-mauve round balls of flowers from early summer to frost. Needs at least 6 hours of sunshine to do its thing, good garden soil and regular moisture. Prune back about 1/3 each spring when new growth emerges. This will provide plenty of new wood for blooms and establish a strong support framework.
