Southern gardeners probably already know this one of our facts about roses. Much like some heat-averse humans, when the temperature is over 90 degrees, roses (or rather, their foliage) will wilt.

Thinking of adding these delightful—but sometimes finicky!—plants to your garden this year? Here’s everything you need to know about growing roses.
