After planting a beautiful array of plants and flowers in your perennial garden for years of enjoyment, the last thing you would expect is for it to become a feasting ground for local deer. Avoid this problem by planning your perennial garden with flowers and plants that are deer-resistant.
A low-growing perennial that will avert deer from entering your garden, common bugle (Ajuga reptans) is a non-native flowering plant that grows mostly in the eastern half of North America, as well as in other states in the west. Common bugle grows from spring through fall less than 4 inches tall, making it a very nice, low-profile groundcover. Its vivaciously blue flowers bloom in mid-summer, and it thrives in full sun to partial shade and moist to semi-dry soil.
Firewheel (Gaillardia pulchella) is a deer-resistant perennial member of the Asteraceae (aster or daisy) family native to the United States. It sometimes behaves as an annual or a biennial, as well. It grows throughout the eastern half of North America, Alaska and a few western states. Firewheel grows from the spring through the fall season, reaching 2 feet in height. Its yellow-tipped, bold red blossoms bloom at various time throughout its growing season, dependent upon its location. Firewheel thrives in full sun and moist to dry soil.
American lily-of-the-valley (Convallaria majuscula) is a deer-resistant perennial flowering plant of the Liliaceae, or lily, family. Also known as "simply lily-of-the-valley," it is native to America and grows in the eastern United States region, between New York and Florida.
American lily grows to 8 inches in height and its small, white, fragrant bell-shaped flowers bloom from mid to late spring. American lily-of-the-valley thrives in moist, well-drained rich soil and in partial sun to full shade.
Deer will not feed on your garden's snapdragon plants. They are considered short-lived perennials that are native to North Africa and the Mediterranean area, according to Floridata. Snapdragon (Antirrhinum majus) belongs to the Scrophulariaceae, or figwort, family and grows 1 to 3 feet in height. Cultivate snapdragons in areas that receive full sun to partial shade, in well-drained, moist, nutrient-rich soil.
Also known as flossflower and bluemink, ageratum (Ageratum houstonianum) is a perennial member of the Asteraceae, or Compositae, (aster) family. According to the USDA Natural Resources Conservation Service, ageratum is both an annual and a perennial. It is a non-native plant that primarily grows in the southeastern region of the United States.
Ageratum is a self-seeding, deer-resistant plant that quickly grows into rounded bush up to 2 feet in height. Native to Central and South America, it prefers full sun and partial shade and moist to semi-dry soil.
