I'll direct you to a couple of resources to guide you in plant selections... First, at our BHG.com website, choose the Plant Encyclopedia's detailed search to find plants that meet your criteria. You can limit your search to your hardiness zone, plant height, color, sun/shade, et cetera, and look at trees, shrubs, evergreens, perennials. Once you've made some selections, go to the ASPCA's website (www.aspca.org). They've got two extensive lists--toxic and nontoxic plants. You can eliminate your plant selections if they appear on the toxic list. I hope this helps!
