Pseudotsuga menziesii 'Seattle Mountain' / Seattle Mountain Douglas-fir

Pseudotsuga menziesii 'Seatlle Mountain' is a medium-growing, upright, conical selection of Douglas-fir with bright, lemon-yellow foliage over a greener interior. The plant needs a bit of sun, preferable in the morning to best develop color. However when exposed to harsh late afternoon sun, the needles tend to scorch, particularly in younger trees. After 10 years of growth, a specimen can be considered mature at 6 feet (2 m) tall and 4.5 feet (1.5 m), implying a growth rate of 6 to 8 inches (15 - 20 cm) annually.

The origin of this cultivar is regrettably unknown. It's first mention is thought to be a "New Ornamentals" website in 2006.
