Here are eight plants that thrive in cool weather. Many of the flowers are available in a variety of colors, so you have a lot of options if you are looking for a particular color. Browse the tables at your garden center or peruse your favorite mail-order nursery’s offerings to find the one that’s just right for your garden.
