Skunk Cabbage Stirs
Skunk Cabbage Stirs
6/72: Jan 25 to 29
Skunk cabbage stirs beneath the snow. Yellow spathes preparing to pierce winter's veil.
風物詩 · Fūbutsushi
A yellow skunk cabbage bud melting its own hole through the frost — the first heat of the year rising from the swamp floor.

The bud holds its heat only a little while. Soon the cold will close in again and the swamp will go silent.
What the season brings?
Late January marks the earliest stirrings of skunk cabbage (Lysichiton americanus) in Pacific Northwest wetlands and swamps. This remarkable plant generates its own heat through thermogenesis, warming its tissues 15-35°F above ambient temperature to melt through snow and ice. The swelling yellow spathes (modified leaves) prepare to emerge, with tight burgundy buds ready to pierce through the cold soil. Look for these early signs along stream edges, in forested swamps, and throughout low-elevation wetlands from southwest British Columbia through Oregon. The plant's metabolic heat also helps volatilize its distinctive skunky scent, which attracts early-season pollinators like flies and beetles.
Convergence chain
Triggered by
Internal thermogenesis — skunk cabbage generates its own heat, raising the spadix to 15–22°C above air temperature; this requires no external warmth trigger, making it one of the earliest wetland events of the year
Enables
Thermogenic heat volatilizes scent compounds attracting early fungus gnats and stoneflies — the first pollinators of the year; bears emerging from dens consume the calcium-rich leaves despite their oxalate content; the standing water around emerging spathes warms first, kickstarting mosquito and midge larvae
The cascade
Skunk cabbage heats its spadix → fungus gnats enter the spathe seeking warmth → pollen transfers between plants → bears tear up the wetland edge consuming emerging leaves → disturbed soil exposes invertebrates → first great blue herons of the season probe the same churned edges → the wetland food web reactivates from a single thermogenic plant
Foods to Mark the Season
Late January continues reliance on winter storage crops—root vegetables (beets, carrots, parsnips, turnips), hardy greens (kale, chard), cruciferous vegetables (Brussels sprouts, cauliflower), and storage alliums (garlic, leeks, onions). Winter squash and apples remain plentiful, perfect for hearty winter cooking.
Things to Do
Search low-elevation wetlands for early skunk cabbage stirrings—look for swelling yellow spathes and melted snow patches around emerging plants. Explore wetland trails at Tiger Mountain, Cougar Mountain, or stream edges throughout the Puget Sound lowlands and Willamette Valley where these heat-generating plants begin their remarkable emergence.
