Tuff Stuff Ah-Ha™ ('SMNHSDD') Sawtooth Hydrangea is a very showy reblooming lacecap in the Tuff Stuff series. The short statue does not limit the number of large flowers, as Hydrangea Ah-Ha™ is a heavy bloomer on both old and new wood. Since it is a serrata, its cold tolerance is also an advantage. The double sterile florets vary in color from pink to purple, depending on the soil pH and amount of aluminum sulfate.
