Will coneflowers spread, get more dense or stay same?
Ok...I know this is not worded the most intelligently, but last year I did three different masses of coneflowers. I started each with about 7 fairly established plants. They did nicely, but I would really like them to be denser with more flowers. So will they come back exactly as last year or will they eventually fill in the space I gave them and cover a bigger area with more flowers? I could always stick a few more out there but if its not needed would rather not waste the money. I did try spreading some of their seeds around from last year and nothing came of that. The plants are coming back nicely but hard to say if its actually 'more'. Thanks
