'Hurricane Blue' and 'Glacier Blue' are especially attractive, but without their labels I probably couldn't tell one apart from the other. It is known for much more blue foliage, so I assume that the various upright pyramidal cultivars with intense blue needles are var. The variety arizonicais the “Corkbark fir” from Colorado, New Mexico and Arizona, but I've never seen it in the wild to know if the crown is also spire-like. The specific name refers to the hairy cone scales, but the distinguishing characteristic is the narrow crown. Even the rootstock is slow, and ours are four-to-five years old when we are able to graft.Ībies lasiocarpa is the “sub-alpine fir,” and it is native to western North America and the Rockies in regions that also contain the mountain hemlock. mertensiana are rare at the garden centers because they are slow-growing and stock trees tend to produce less-than-vigorous scion shoots. Rainier by Elsie Fry who named it for her daughter. 'Elizabeth' is a spreading form, growing twice as wide as tall, and was discovered on Mt. 'Bump's Blue' and 'Powder Blue' are Buchholz introductions, while 'Blue Star' was selected in 1965 by L. mertensiana – it's not compatible with the other Tsugas – and it's a long process to get the slow-growing conifer to a salable size. In any case we graft some of the most blue cultivars onto seedling T. It went from being classified as Pinus mertensiana to Hesperopeuce mertensiana before being lumped into the Tsugas. mertensiana should be included in the Tsuga genus because it is very different form the rest with its radially arranged needles and relatively large Picea-like pendant cones. mertensiana was named for Karl Heinrich Mertens (1796-1830), a German botanist who explored the coast of America aboard a Russian ship. Foliage is blue-gray, but in July light-blue new growth sparkles diamond-like on the tree. I favor it primarily because I am most happy when I am away from work and everybody with their problems and I can hike into the thin air where the hemlock hovers on the slopes of our Cascade Mountains. My favorite conifer might be Tsuga mertensiana, the “Mountain hemlock” from the mountains of western North America.
