This toxic native woodland flower is blooming everywhere right now

Native Plants

The clusters of small white flowers popping up in the shady, disturbed edges of your neighborhood woods are white snakeroot, a native plant that's toxic to livestock and famously linked to 19th-century "milk sickness" deaths, so it's worth learning to identify even though you shouldn't touch or eat it.

White snakeroot is a native woodland wildflower that's suddenly showing up all over iNaturalist, with 1,450 confirmed sightings logged in a single week. It's blooming right now in shady spots and along forest edges, easy to spot thanks to its fuzzy white flower clusters. Fun fact for plant nerds: this is the plant that poisoned cows' milk and killed Abraham Lincoln's mother, so admire it from a distance.

Phenology is the study of recurring biological events in plant life cycles—such as flowering, fruiting, and germination—and how these events are timed in response to seasonal and climatic conditions. This research is essential to plant science because phenological patterns directly influence
