For a beautiful patio filled with potted plants, there are a variety of sizes of pots and a variety of plants. Container gardens are especially suited to Wisconsin, where rapid temperature changes can take place in the spring and fall.

Wave petunias are unusual in the petunia world because they have a dense, spreading habit with no deadheading required. Wave petunia plants never need to be pinched back. A single plant will reach 8 to 10 inches tall and will spread 30 to 48 inches. This plant is ideal in a large garden pot or hanging basket.

Many geranium varieties have colorful variegated foliage, which adds a bonus splash of interest to the patio. You can start seeds indoors, purchase plants, or use cuttings from last year’s geraniums.
