The USDA, or the United States Department of Agriculture, provides a Plant Hardiness Zone Map.  It is the standard by perennialsawhich gardeners and growers determine which plants are most likely to thrive at a certain location.  The planting and growing season in Zone 6 ranges from mid-March (after the last frost) through mid-November, which is considerably lengthy.  Most of Ohio falls in zone 6; the majority of Northeast Ohio is in Zone 6a.  (This means the coldest the area gets is between -5 and -10 degrees Fahrenheit.)  So what exactly does that mean to a Northeast Ohio gardener?  To get a more accurate breakdown, we recommend you visit the USDA website — or check out this article which was published shortly after the hardiness zone map was updated by the USDA —

So what perennials are suited for Zone 6?  Gardeners and growers need to be aware that the weather in this area can abruptly change, which all of us are accustomed to – it can be 80 degrees and drop to 40 degrees the very next day!  Only in Cleveland, right!?!  Despite the temperature swings, it’s actually a very favorable environment – a long growing season complimented by generally mild temperatures.
