What is perennial in my garden?
i have
lupine(which never made it fron seedling form No blooms just star like leafs about and inch wide and less than 2" tall)
coreopsis, gaiardia, purple coneflowers, baby's breath, blue fax(I don't think i have any of these but they are listed in my seed mix) papover orietale...

I have bad soil almost like clay. I was wondering if I was to mix in a better top soil for next year how could I do this without hurting the perennials that are already growing there?
