LIMELIGHT HYDRANGEA
These paniculata hydrangea hybrids are one of the few hydrangeas that actually thrive in the sun . They need at least 4 – 6 hours of sun a day , are hardy in zones 3 – 9 , and reach up to eight feet tall . The bloom starts out as a lime green color , shifting to bright white in the summer , then fading to an array of pink , red , or burgundy in the fall . They are not fazed by the cold winter and are excellent cut flowers . For smaller gardens , look for “ Little Lime ” that matures at about five feet .
