Wild Flowers for Honey Bees in the Central United States
Below is a collection of bloom times for some of the wildflowers used by pollinators in the American Midwest. Included are wild-growing plants that provide some sustenance to western honey bees (apis mellifera). Their importance as nectar and pollen sources varies greatly, as does their density of distribution. Some of these flowers would only be worked when little other forage is available. I’ve withheld any plants that are predominantly used in domestic landscapes. This list is in no way exhaustive—it only includes my personal observations, so if I haven’t seen and identified a flower myself, it’s not shown here.
The map above shows the approximate area of reference, centered on Missouri. Beekeepers in Arkansas, Illinois, Indiana, Iowa, Kentucky, and Tennessee may encounter a similar selection of flowers. Based on bloom dates reported by other beekeepers in the region, for every 100 miles south of St Louis the bloom times will be about 1-2 weeks earlier, and for every 100 miles north of St Louis it will be about 1-2 weeks later. St Louis city itself also sees blooms earlier than what’s shown below, because the temperatures are consistently warmer there. I do the best I can to identify flowers being used by honey bees, but I’m not a botanist—if you see a mistake or an obvious omission, please let me know by sending a message through the Contact page.
