May is a month when so many collections plants are blooming - we always enjoy guiding the public to see these plants displaying their flowers. Humans love flowers for their beauty or scent, but what are they?  How do they work? The science of the flower is amazing too.  Please join us for a casual spring walk in the arboretum to learn more about flowers, bees and pollination.  UW Botanic Gardens is committed to enriching the lives of all community members with free public tours.
