USDA Hardiness Zones:
Cool season annuals typically are planted in the fall or early winter and flower in early spring under moderate temperatures. This group of plant materials includes: pansies, snapdragons, violas, dianthus, flowering cabbage/kale, etc. Because cool season annuals flower in the spring when conditions are mild, most have limited heat tolerance.
As a result cool season annuals do not receive a high Earth–Kind® index despite their outstanding landscape qualities.
