Here in the "Evergreen State", fall is the time of year when the high country is illuminated with the beauty of Larix occidentalis, our "not so ever green" Evergreen.
Reportedly discovered in western Montana in 1806 and finally described and classified by Thomas Nuttal in 1834, Larix occidentalis or the western Larch is often a traffic stopper along Highway #20 near Washington Pass this time of year. And for good reason.
The bright yellow-orange coloration of the leaves (needles) of Larix occidentalis preparing to fall to the ground, set against new fallen snow and a backdrop of the blue sky is a combination worth pausing for.
Part of what makes the western Larch so unique here in the Pacific Northwest is that it is the only one of our conifers to lose ALL of its leaves (needles) EACH year. In fact, it is reported to be one of only three conifers to do so -- the others being the Bald Cypress and Dawn Redwood.

While all conifers technically lose their needles, they do so over a cycle of 2 to 15 years, with the old needles being replaced by new green ones. For instance, most pines keep their needles for three or four years. Hence, their "
ever green" appearance.
If you are here in the Methow Valley this week, be sure to plan a hike somewhere up high to enjoy the brilliant beauty of Larix occidentalis!
