Picea abies 'Aarburg' is a truly bizarre, twisted, weeping wonder. Overall, its form is upright, but tends to meander as it finds its way skyward. After 10 years of growth, a mature specimen will measure 12 to 15 feet (4 - 5 m) tall, an annual growth rate of 15 to 18 inches (37 - 45 cm), sometimes upward, sometimes outward. Needles are typical dark-green for the species, but at 0.32 to 0.6 inch (8 - 15 mm), they are somewhat shorter.
This cultivar originated as a seedling selected in 1965 by Andreas Haller Nursery of Aarburg, Switzerland. This plant makes a very strong statement in a large landscape or arboretum.
