The Best Trees and Shrubs for Ontario Pollinators

So many times, people will inquire which trees and shrubs to plant to help feed our struggling pollinators.  Finally because of these numerous inquiries, I have constructed a listing of native trees and shrubs that bloom from April to September.   Different criteria were used to make our choices.

What makes our choices slightly different is that we base selection on bee appeal.  Universities rate plants based on their bee appeal.  Using these bee appeal value, only plants that were rated as very good or excellent were chosen.  Bee appeal usually translates to the production of vast amounts of pollen and nectar available to pollinators.  Also, our choices are native since native trees and shrubs have formed intricate relationship bonds with our native pollinators.  And lastly, we wanted plant choices to extend food availability for the whole season for hungry insects.
