Big Tree Ridge, Section Line Trail, Swamp Trail & Puget Power — Thursday, May. 9, 2024

Issaquah Alps > Cougar Mountain
Wild Ginger is blooming! One spot is just to the east of the giant Doug fir on the Big Tree trail, on the south/uphill side of the trail. Many of the blooms are in plain sight (I did use a light to get photo 1, these tend to grow in shaded places).  Tiger Mt is exploding with plant growth, lots of shade from the canopy above and flowers every step of the way. There are lots of trailing blackberries in bloom which attract bees and bumblebees. There were lots of spring beauties out on this sunny day (photo 3), very pretty arctic stars (photo 4), and lots of other blooms (a few more flowers and pollinators in the slideshow, there are a few non natives in there, I can't shun them, especially when there's a pollinator on them).
I like the old road above Sunset Way that runs parallel to the Wetlands trail; you'll find baldhip roses (and other species of the rose family not yet blooming), western trumpet honeysuckle (photo 2), and lots of pollinators (albeit a lot of them on the many old-growth scotch brooms). By trying to identify the flowers on the open areas of Tiger, I am learning a lot of non-natives.
