Every March through April the question comes up. “What’s with the red pollen my bees are bringing in?” So I’m writing this post in the hopes that whoever Googles the question will find the answer here. There are several plants that produce red pollen later in the year. But the main plant that produces large amounts of red pollen in spring is purple deadnettle (lamium purpureum). In my area of Pennsylvania, it blooms right after red maple and long before dandelions. Huge blankets of deadnettle grow in farm fields before herbicides are applied, in unmanicured lawns, and along roadsides.
