Although strobus is often showed as hardy to zone 3 and undoubtedly there may be a few that will do well in zone 3 most winter burn very badly and become disfigured. My experience in zone 3a is that Fastigiata is not hardy here.
Iseli describes a cultivar by this name stating in their catalogue ... 'A rapid-growing, narrow, upright tree with long and slender Blue-green needles that give this useful tree a soft-textured appearance. Bluish green in color.'
Bob Fincham shows a mature specimen of this cultivar in one of his 2 videos on cultivars of conifers. His commentary, although complimentary of the cultivar in its early years, describes an untidy plant when it grows to a large size. He informs that the fastigiate branches begin to open up and outward giving the plant a less pleasant appearance than its younger form.
