Picea abies 'Hiimuaa' / Hiimuaa Norway spruce

Picea abies 'Hiimuaa' is a diminutive, perfectly globose selection of Norway spruce, arguably one of the slowest growing known cultvars. Fine, symmetrical branches appear to radiate from a central point and needles are extremely tiny, approximately 0.12 inch (4 mm) long and dark, blue-green in color. Buds are quite conspicuous, appearing like tiny brown pearls on the plant surface. After 10 years of growth, a mature specimen will measure 6 to 8 inches (15 - 20 cm) tall and side, an annual growth rate of well under 1 inch (2.5 cm).

This cultivar was found in the wild in 1968 on the Estonian island of Hiiumaa.
