Tsuga canadensis 'Devil's Fork' is a well-branched, semi-dwarf selection of Canadian hemlock that grows about 6 inches (15 cm) per year when young, but can grow over 12 inches (30 cm) per year when older. Mature specimens look more dense when growing in full sun, but can grow well in heavy shade where the branching structure will be more apparent. The plant does not grow a central leader, but has multiple stems, branching at a very acute angle or fork with both tines about equal in diameter. Branches are thin and flexible and usually don't hold snow, so splitting after a heavy snow event is rare. New growth is pendulous during the growing season, but eventually straightens to a more vertical branch.
This cultivar was apparently discovered growing in the wild, but the circumstances surrounding the originator and its inclusion into the nursery trade are currently unknown.
