Busy Bee! Close up of a furry black Bumble Bee with bright yellow stripes, gathering nectar from bright and colorful purple flowers in the garden. A pollinator plant, these flowers are popular with our very necessary Bumble Bees and butterflies. World Honey Bee Day on the third Saturday in August brings a buzzing celebration for beekeepers, honey lovers, and all blooming things. We depend on honeybees for our survival.
