Picea abies 'Weeping Blue' is a fast-growing strictly weeping form of Norway spruce. If staked, a mature specimen will measure 6 feet (2 m) tall and 4 feet (1.3 m) wide after 10 years. At that point the plant will "knuckle over" and form a wide skirt unless the grower finds a longer stake. If not staked, 'Weeping Blue' will become a broad ground cover, mounding up a bit in the center. Regardless of how it's cultivated, terminal leaders will extend at a yearly rate of 6 to 8 inches (15 - 20 cm). Needles are species-typical in length are are distinctly grayish blue in color.
This cultivar originated as a seedling selected in the USA in the late 1980s. Iseli Nursery, Boring, Oregon introduced it to the nursery trade in 1991 under the illegitimate name, 'Glauca Pendula.' This name violated two laws of plant nomenclature - Latin cultivar names are not allowed after 1959 and a specific cultivar name can only be used once within a genus. This error has since been corrected.
