A recent article in Entomology Today revealed a win/win for ag-producers when wildflowers were planted next to their crops. Several species of wild bees were attracted to the wildflower strip and conversely the nearby crops. Producers had the additional bonus of being able to harvest wildflower seeds for retail purposes. Researchers observed over 200 species of native bees in the course of the study.
The ET article referenced “Wildflower Seed Sales as Incentive for Adopting Flower Strips for Native Bee Conservation: A Cost-Benefit Analysis” printed in July 2019 Journal of Economic Entomolgy (authors C. Delphia, K O’Neill, L. Burkle)
“I think the most important finding is that we provided evidence of another potential economic benefit of wildflower strips,” Delphia says. “It’s important to demonstrate all the economic benefits—and drawbacks—of planting flower strips if we want to increase adoption of this strategy. Furthermore, we have helped bees using native plants, which promotes native plant conservation in addition to wild bee conservation.” Source: https://entomologytoday.org/2019/08/15/wildflower-strips-bring-farmers-extra-money-while-helping-native-bees/
There are quite a few books and websites that name native plants specific to our area that encourage pollinators (bees and butterflies) to visit. Here are a few:
