Researching native plants for my yard in Cincy. Lots of Ohio/Midwest Native Plant lists, but local nurseries are not staged to carry them. Natorps has a list of natives they carry, but when I went to purchase last year, very few plants on their own list were available. Where are options for shrubs and flowers? I need Butterfly Weed, Bee Balm, Yellow Water Iris. Where can I get some Mayapple starts? Chokecherry, Nannyberry? Thanks!
