Phenology
iNaturalistWestern skunk cabbage is a key early-spring indicator species — if you walk near wetlands or stream banks in the Pacific Northwest, its sudden appearance signals that winter is truly over and that the wetland ecosystem is waking up.
Western skunk cabbage is a wild plant that grows in soggy, swampy areas in western North America and is famous for blooming in late winter or early spring — sometimes even melting through snow. It gets its name from the strong, skunk-like smell it produces to attract pollinators like flies and beetles when almost nothing else is flowering. Hundreds of nature lovers spotted and recorded it this week, giving scientists a real-time snapshot of where and when it's blooming.
Key Findings
138 research-grade observations were recorded on iNaturalist in a single week, indicating a strong seasonal bloom pulse.
Western skunk cabbage is among the earliest-blooming plants of the year, often emerging in February–April across the Pacific Northwest and into Alaska.
The surge in citizen science sightings provides phenological data useful for tracking how climate shifts may be altering the timing of early spring wildflowers.
chevron_right Technical Summary
Western skunk cabbage is one of the most-observed plants on iNaturalist this week, with 138 research-grade sightings logged by citizen scientists. This spike in observations likely reflects its early spring bloom, when it pushes up through wet, muddy ground before most other plants emerge.

Lysichiton americanus, also called western skunk cabbage (US), yellow skunk cabbage (UK), American skunk-cabbage or swamp lantern, is a plant found in swamps and wet woods, along streams and in other wet areas of the Pacific Northwest, where it is one of the few native species in the arum family.
