The scientific name for the two varieties of coneflowers I listed earlier for planting are:
Echinacea Purpurea (Purple Coneflower)
Rudbeckia amplexicaulis (Clasping Coneflower)
Coneflowers actually cover four families of plants. The one I am planting the most of is the Purple, which as you can see is a member of the Echinacea family. Yes, it is that same herb many people buy to fight colds and infections. The roots and the leaves of this plant are useful for this purpose! So, next autumn.. visit some of the bombing sites and collect some. It is best to collect them after the heads have gone to seed.
There is also a special Coneflower which would be perfect for this project. Echinacea tennesseensis (Tennessee Coneflower) is a plant which is endemic only to certain areas of the state. However, from my reading, it should work in the area because of Urban empty land's similarity to prairie soil (Dry, grassbeds, etc.) The problem is, the seeds are quite pricey. So, if anyone is interested in sponsoring a bombing of these seeds to help this endangered plant, please contact me!
By the way, 100.00 will buy over 20,000 of these seeds. Let's save a native endangered plant!
