I snapped this a few weeks back. The echinacea, also known as the coneflower, was The nectar font of choice for the bees and butterflies. Frequently there would be three or four bees on one flower. Buzzing and humming even on close approach. Occasionally they would bump into each other when rotating around the flower.
Pictured is a native bee (top) and a non-native honeybee. Amazingly this plant still has flowers on it today but its nectary has seemingly dried up as there is very little insect action on the plant.
Humans use this member of the daisy family to help with a lot of cold-like symptoms…
These perennials are great to plant in an area where you can easily observe the action. Easy to care for and at least the “Giant Coneflower” lasts July through August.
