The Horticultural Symposium has evolved into a twice-yearly event enthusiastically attended by devoted gardeners in southern Idaho. Speaker Mike Heger entranced the audience on September 9 as he narrated dazzling slides of the best perennials for southern Idaho.
Nothing is further from the truth.
I still maintain that some of the best gardens in the U.S. are in the North. Formerly with the Minnesota Landscape Arboretum and now co-owner of Ambergate Gardens in Chaska, Minn., Heger bases recommendations of individual varieties on foliage as well as bloom. Think of combining them in your landscape with fall-blooming perennials. It makes us wonder why that's there. Every curve must be justified and appear to be logical.
