Origin:

This cultivar is 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 (30 cm) tall grafted plant from Biltmore Nursery of Asheville, North Carolina, under the name 'Tortuosa' (which is a proper dwarf).
