Picea abies 'Indet' / Indet Norway spruce

Picea abies 'Indet' is a fairly fast-growing, broadly upright selection of Norway spruce with dense, semi-fastigiate branching an dark green foliage. After 10 years of growth, a mature specimen will measure 6 feet (2 m) tall and wide, an annual growth rate of 6 to 8 inches (15 - 20 cm).

This cultivar describes an old unique plant that lives in the National Arboretum in Washington, D.C., USA. Given that it resides in the Watnong collection, it can be presumed that the original plant was selected and named by Don and Hazel Smith of Watnong Nursery, New Jersey. It is certainly no longer, if ever in cultivation, but there are potentially other specimens extant in old arboretums.
