Last summer I saw photos of cottongrass growing in meadows in Montana and I thought I really need to go see those places! Earlier this summer, I saw a small patch of cottongrass on one of my hikes in a small wet meadow and it made me think about a large wet meadow that I like to visit. Fortunately I was there earlier this month and indeed, there was cottongrass, lots of it! Why haven’t I noticed it before?
I learned that it likes acidic conditions and since this place has heather and huckleberries, I assume the soil is acidic. It also likes peat bogs. Anybody know of any peat bogs in good condition? There are many varieties of cottongrass (Eriophorum sp.) growing in vastly different climates around the world but all seem similar, needing acidic conditions. Washington Wildflowers lists one for our state – Chamisso’s cottongrass or russet cotton-grass (Eriophorum chamissonis). The range map does not show it in this area.
