The very earliest Kentucky Bluegrass flowers (Poa pratensis) have begun releasing pollen in the City of Green Bay. These are only the plants on extreme sites, such as along the south side of buildings, etc. The general flowering may not begin for several days. For 12 years of phenology observations in Green Bay, the average first day of general flowering (anthesis) for Kentucky Bluegrass is May 29, and the earliest was May 16. If you are allergic to Bluegrass pollen--get ready.
