Choosing plants that can withstand heat and cold is an important first step for maintaining a year-round thriving garden in locations that experience weather extremes - intensely hot summers and freezing winters.

Choosing heat-tolerant plants that can also withstand the cold means you can enjoy seasonal interest and don't have to worry about your garden looking lackluster.
