Late April through early May transforms camas meadows into breathtaking seas of blue flowers across the Pacific Northwest, particularly in the Willamette Valley, Puget Sound prairies, and southern British Columbia. Common camas (Camassia quamash) produces tall spikes of star-shaped blue-purple flowers that once covered hundreds of thousands of acres before agricultural conversion. These bulb-forming plants were one of the most important food sources for indigenous peoples throughout the region, with tribes managing meadows through burning and selective harvesting for thousands of years. Camas bulbs were pit-roasted for days to convert inulin into digestible sugars, creating a sweet, nutritious food that could be dried and stored. Today, remaining camas meadows are conservation priorities, with places like Camassia Natural Area in West Linn, Oregon preserving these culturally and ecologically vital ecosystems.
