Landscape Plants of the Upper Midwest is an interactive guide that is specific to the upper Midwest of the United States (hardiness zones 3, 4 and 5), providing complete and accurate information on more than 600 species and varieties common to this region.

While a selection of cultivars is provided for many species, this site is not intended to be a complete record of available varieties. The growing plethora of cultivars, many of which are released to fulfill marketing goals rather than to offer well-tested superior plant varieties, makes it impractical to provide an up-to-date record of these often transitory cultivars. Efforts are made to add varieties as their merits warrant inclusion.
