"Let's Dance Can Do!® hydrangea is an excellent rebloomer, requiring only a short period of growth in order to create new wood blooms.  It also sets its flower buds along the entire length.  This means that if this hydrangea is cut back or damaged by cold temperatures, those lower, old wood buds will still develop into flowers.  It's a huge leap forward .  Abundant, semi-double, star-like florets make the lacecap flowers very showy." -   Spring Meadow Nursery [Hydrangea]
