Abies alba 'Green Spiral' is an upright weeping form of European silver fir with a strong central leader, with the branches spirally descending around it, with the lateral branches and stems pointing downward in short curves. Needles are short and dense.
[ Arthur Lee Jacobson in North American Landscape Trees ] 'Green Spiral' is a twisted, narrowly pendulous, semi-dwarf, 30-feet (9 m) tall, cone-less tree, that is propagated by specialist nurseries.
This cultivar is an one clone, but was only named in 1979 by Sir Humphrey Welch. The original specimen was received by Secrest Arboretum of Wooster, Ohio in 1916 as a 1 foot (30 cm) tall grafted plant from Biltmore Nursery of Asheville, North Carolina, under the name 'Tortuosa' (which is a proper dwarf).
