The source is an excerpt from a guide identifying thirty essential plants for creating a backyard bee sanctuary, emphasizing the critical role of pollinators, such as honeybees and native species, in sustaining agriculture and ecosystems. It establishes that declining bee populations necessitate gardeners' intervention by planting habitats rich in nectar for energy and pollen for protein. The guide advocates for prioritizing native plants and specific bloom characteristics—like blue, purple, yellow, or white open shapes—while avoiding the use of pesticides. Each of the thirty listed plants, including Lavender, Bee Balm, and Aster, provides specific details on its attractiveness to bees, bloom time, zone, and optimal growing tips for fostering a supportive environment year-round.
