annuals for undisturbed prairie?
My acre of prairie has (in addition to grasses) perennials such as aster, goldenrods, Gaillardia aristata, Mexican Hat, etc. But I hate to give up on some of the more showy annuals, especially Black-eyed Susan, Meadow Pinks, and Lemon Mint. Most annuals seem adapted to grow in disturbed sites, so I'm wondering which ones folks have had luck with in relatively stable, undisturbed warm-climate prairies? Alternatively, what are the best strategies for keeping the above-mentioned annuals around year after year? I give my meadow one good mowing in March, and that's it.
