‘Little Lamb’ is a compact shrub with a mounding habit that stands 6 to 8 ft tall and 4 to 6 ft. wide. It has large, conical flowerheads that are a mixture of showy but sterile flowers and smaller, fertile but nonshowy flowers underneath. The flowers emerge white in July, and turn pink as they mature. The blooms will continue into September. It does well in full sun to light shade and is moderately drought - tolerant. The color of the flowers is not affected by the pH of the soil. It blooms on new wood so the flowers are not susceptible to late spring frosts. This is a hybrid of Hydrangea paniculata which is native to Japan, China and Korea where it grows at altitudes up to 4,000 ft.
