All of our nearly 500 species of native bees are dependent on pollen to feed their young. No flowers, no bees. Like flowers, each bee species has its season. During a bee’s flight time they are often dependent on the pollen from only a small group of plants, ignoring the rest.

What you plant has consequences for the bees you support on your property. We will travel through a year in the region, tracking the flowers and their bees, or…the bees and their flowers (depending on your point of view!).
