Different wildflower mixes were studied in three regions of North America where production of pollinator-dependent crops is high: Florida, Michigan, and California.  Results showed designing mixes to provide continuous bloom throughout the growing season is critical to supporting the greatest pollinator species richness. Wildflower mixes may be particularly important for providing resources for some taxa, such as bumble bees, which are known to be in decline in several regions of North America.
