Flowering trees are beautiful to look at in the springtime, but also provide a necessary function in our food chain. Flowering trees like the cherry tree (pictured) provide a much needed food source for bees and other pollinators after a long winter. In turn, those pollinators provide a service to the human species by pollinating many of the fruits and vegetables we eat in the summer and fall. If you enjoy your summer and fall harvests, plant a tree that flowers in the spring.
