Do you deadhead your coneflowers? I don't. And let me tell you why. Like most native plants and even most native insects, different stages of development offer different roles to the ecosystem. When the flowers first open, they are loaded with pollen and nectar, which are both food sources for adult insects. They'll eat them themselves, or some of them will take them back to their nest to feed their young. The next stage is when the flower petals start to turn brown and fall off. That means the flower has been pollinated. It doesn't need to invest in the petals anymore to attract insects. It just needs to focus its energy on turning the center of the flower into seeds, which is food for birds. American Goldfinch. Traditionally in gardening, we teach people to deadhead to encourage more flowers, but let me turn the camera around and show you without deadheading, I'm still getting many successions of blooms. On June 24th, you can see Echinacea purpurea, or purple coneflower. That's the round flat flower. They're open on June 24th already. These other more narrow coneflowers, they're called pale purple coneflower. They open a few weeks earlier. We aren't talking about that variety in this video. So the flowers from the 24th are turning brown and creating seeds. I've got beautiful flowers open. I've got lots of buds that haven't even come up yet. So we've got flowers here for a month, and there's still more coming. So I don't need to deadhead to get lots of flowers. And if I leave all of them up, I'm feeding all the insects and leaving them up for seeds for the birds. Now this giant patch of coneflowers was started with only three plants. I have a video coming out about how to collect the seeds and leave some for the birds and use those seeds to expand your patch of coneflowers. Stay tuned.
