Petunias are among the most versatile annual flowering plants. Instead of asking what color they come in, the better question might be, “Is there any color they don’t come in?” We offer about 25 combinations of colors and patterns, from single white petunias to stunning two-toned pink and yellow. Choose patterned blooms too, with stripes, spots and other multicolored patterns.
Petunias require little care, but watering and lots of sun. Feed Petunias with a balanced fertilizer at planting time, and work some compost into the soil. The plants prefer average water and full sun.
The Best Way to Use Petunias
Grow petunias in nearly any sunny spot in the landscape, on balconies, patios, front porches, garden beds or hanging baskets. Petunias are easy-care, full-sun annuals and perennial only in warm zones. Most petunias grow to less than a foot tall and spread to 2 to 3 feet by summer’s end. Petunias grow in mounds, but their stems can trail over containers and hanging baskets.
Use petunias as ground covers, in garden planters, as mass plantings, and garden borders.
Great for wildlife like hummingbirds and butterflies.

Petunia Companion Plants
Petunias make excellent companion plants for taller flowering plants, ornamental grasses, or plants grown for foliage that can take full sun. Petunias also act as a natural pesticide, and work great next to vegetables planted in the garden. Other great options to plant next to petunias are snapdragons, lupine, black-eyed-susans, iris and allium. Here are some of our favorites:
