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.
