What are the best plants for native bees?
Native flowering plants and plants that grow food are the best pollen and nectar sources for bees. Native flowers have evolved with bees to provide nectar and pollen and native plants are more attractive to bees. Many food-growing plants need pollination so they can grow fruit and seeds and food plants also do a good job of attracting and feeding bees.
Cultivated plants may lose their nectar or pollen production during the breeding process. Weeds like dandelions (introduced) and clover (many types are native to North America) can be a great pollen source for hole-nesting bees. Herbs are also attractive and effective flower feeders for bees.
