Marsh Marigold
Caltha palustris
Honeybees visit marsh marigold for its abundant early-season pollen and moderate nectar, providing crucial forage as colonies build up after winter. Peak bloom occurs in April to May in northern regions. It requires consistently moist or wet soils and is not invasive, though all parts are toxic to livestock.
