Tsuga mertensiana aka Mountain Hemlock

Tsuga mertensiana, commonly known as Mountain Hemlock, is an evergreen coniferous tree native to the west coast of North America, with its northwestern limit on the Kenai Peninsula, Alaska, and its southeastern limit in northern Tulare County, California. It is a large tree, with adult specimens reaching heights of up to 59 m (194 ft). Its bark is thin and square-cracked or furrowed, and grey in color, and its crown shape is conic in young trees, becoming cylindric in older specimens. Needles are bluish-green in color, 7 to 25 mm (0.3 to 1 in) long, arranged spirally all around the shoot. Cones are small and cylindrical, 30 to 80 mm (1 to 3 in) long, with thin, flexible scales 8 to 18 mm (5⁄16 to 11⁄16 in) long. Mountain Hemlock is an uncommon houseplant, which needs regular watering and should be situated in a bright spot no more than 1 foot away from a window. It should be planted in well draining soil, and should not need added fertilizers if you repot it each time it doubles in size.
