Finally a book that's not professorial and gets to the point!McClure not only compiles lists from several regional experts, she includes down-to-earth quotes from them that lends a lot of authenticity to their recommendations.
She's upfront about what grows well in our alkaline clay soil and what plants can honestly handle the extremes of heat, humidity, drought, rain, cold and wind charactistic of this area.
Another excellent reference for those of us in zones 5 & 6 is Ezra Haggard's Perennials for the Lower Midwest. It's more conversational than a list book, but the accessible text is packed with advice and never rambles. The format gives each plant a page of text with a full-color photo on the facing page.
