I attended a speaker session put on by Cal. Hort.
The speakers were two authors of books on gardening on the Prairies.
Perfect Perennials for the Prairie Gardener by Dawn Vaessen.
Edible Plants for Prairie Gardens by June Flanagan.
There is a brand new book coming out shortly called 'Landscaping with Daylilies'. A few of the members of the daylily club I belong to have various pictures, taken in their yards, included in it.
That sounds like a useful book---will looj for it.
