Flowering Bee Lawns
I went to a "bee college" a few weeks by zoom ago and Marla Spivak was one of the instructors. One of her presentations was about Flowering Bee Lawns. Here is a link to the toolkit for land managers:
What are flowering lawns? Flowering lawns are turfgrass areas mixed with low-growing, perennial flowers, like white clover, self-heal, and creeping thyme. You can walk on bee lawns and mow them just like a regular lawn, and the flowers provide food for bee pollinators.
More than 56 species of bee pollinators were found just on white clover growing in park lawns in Minnesota. That's nearly 15% of the bee species in the whole state! Adding additional flower species to lawns supports even higher bee diversity and ensure they are not competing for the same resources. The toolkit in the above link talks about other species of flowers to ad to a flowering lawn.
