Mountain Hydrangea lives up to its name. It shares the showy blooms and beautiful pink or purple color of big-leaf hydrangeas, but because it grows wild on the chilly mountain tops instead of the mild seaside, it naturally developed substantially better cold tolerance. The sturdy lacecap blooms will be bright pink or deep purple-blue, depending on your soil pH, and the handsome dark green foliage resists wilting. Found these in Blowing Rock, North Carolina.
