Siberian Peashrub

Caragana arborescens
In the United States: Introduced · also called Siberian pea tree

Honeybees forage on Siberian peashrub for its rich early-spring nectar and pollen from fragrant yellow pea-like flowers. Peak bloom aligns with late spring in temperate climates, offering vital resources when few other plants are flowering. This nitrogen-fixing shrub thrives in poor, dry soils but can spread aggressively via seeds, necessitating monitoring and occasional pruning.
