Citizen science observations across two centuries reveal a dramatic, climate-driven shift to earlier leaf out and flowering, which varies across settings, species and functional groups. Plants in urban areas, insect pollinated trees, and early-season species show the greatest rate of advancement overall. This unprecedented comparison of historic-modern network observations illustrates how long-term monitoring and citizen science efforts are invaluable for ecological forecasting and discovery.
