Welcome to the World of Rose Gardening or Rose Gardening World.  Take time and smell the roses.  Roses have been around for millions of years which just prove that roses are not difficult to grow. The Rose is also our National Floral Emblem and the state flower of several states.  Here at Rose Gardening World, you’ll find rose articles that will educate you about roses – its history, rose culture, rose profiles and even rose verses all in one place.  So visit Rose Gardening World often. 

With the climate changes, the United States Department of Agriculture (USDA) Plant Hardiness Zone Map is not at all reliable.

The USDA Plant Hardiness Zone map was revised in 1990 and as every gardener knows, there is a warming trend marching northward throughout the country.  The American Horticultural Society revised the USDA Plant Hardiness Zone map in 2003 at the request of USDA but when submitted, the USDA rejected it because there was such a dramatic change in the climatic condition as compared to the 1990 map.  The USDA decided they will do a change based on 30 years data.  But averaging the data for such a long period of time will not reflect the recent warming phenomenon.  By doing this, it will also decrease the liability for the nursery crop insurance program.  It is interesting to know that the USDA Risk Management Agency operates in partnership with the private insurance companies. 

Meanwhile, the National Arbor Day Foundation issued its own Hardiness Zone Map in 2006 which is a better guide for us gardeners because it is based on data from 1990 to 2004.
