Abies alba 'Green Spiral' / Green spiral silver fir
Abies alba 'Green Spiral' is a weeping form of silver fir with a strong central stem but the branches spiral around the it with the lateral branches and stems pointing downward in short curves. Needles are short and dense.
An old 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 ( .3 m) tall grafted plant from Biltmore Nursery of Asheville, North Carolina, under the name 'Tortuosa' (which is a dwarf, properly).
Green Spiral is a twisted, narrow pendulous, semi-dwarf 30 feet (9 m) tall, coneless tree that is propagated by specialist nurseries.(Jacobson, 1996)
Abies alba 'Green Spiral'
These specimens are growing at Secrest Arboretum in Wooster, Ohio. They are by far the best examples of this cultivar I have ever seen. This photo does not do them justice.
For scale the street sign in front of the plants is about 10 feet tall.
These particular specimens are mentioned in the Manual of Cultivated Conifers by Krussman. They are reported to be planted as a high graft in 1916. Delivered from Biltmore Nursery as Abies alba 'Torulosa'.
