bluebonnet

Lupinus texensis

Honeybees avidly visit Texas bluebonnets for their abundant nectar and nutritious pollen, making it a key early-spring forage source in its range. Peak bloom occurs from March to May, aligning with bees' need for post-winter resources. As a winter annual, it self-seeds in well-drained alkaline soils but requires full sun and seed scarification for reliable establishment; seeds are toxic to grazing animals.
