Picea glauca 'Little Globe' has medium-green foliage with prominent, large, foliar buds on a compact, globose plant. After 10 years of growth, a mature specimen will measure 24 inches (60 cm) tall and wide, an annual growth rate of 2 inches (5 cm).
[Iseli Nursery online catalog] This neat conifer will complement any rock garden or other home landscape use and is virtually maintenance-free to maintain its shape. Grows 2-3" per year.
[Porterhowse Farms online catalog] I will comment that while Iseli literature shows this as a zone 4 plant, other catalogs list it all the way down to zone 2. From my own experience in Zone 3a I have had no problems with winter hardiness.
'Little Globe' was registered at Arnold Arboretum, Wellesley, Massachusetts, by Verkade Nursery, Wayne, N.J. This cultivar originated as a witch's broom found in 1959 at Waterford Works, Wayne, New Jersey.
