This is another plant that deer dislike: Echinacea purpurea. aka Purple coneflower. It is quite prolific in its ability to reseed. Since it is perennial, it takes a few years from seed, but once it is established, it just goes and goes.
Every year when I cut it back, I save the seed heads. Got lots if you want some. In fact, many purple coneflowers that you see around Five Forks came from my garden. Not the red, orange, or yellow ones, they are nursery grown, and I suspect they are annuals. But Jim Brunst and I are going to experiment with them this fall to check out their ease of propagation. We'll see what happens. He's got some great big Denver Daisies too, that we will play with.
Meanwhile, know that nobody in my life should ever have to pay $$$ for Echinacea purpurea. Just come get the seeds. That also goes for DILL, OREGANO, MARIGOLDS, and probably some others.
We will talk about seeds some other time. Fascinating subject, and really FUN process. Can't wait to share.
HAPPY GARDENING!
