Perennials, which are flowers that come back year after year, are a common choice for many gardeners. Selecting plants that are compatible with the amount of light available in your garden is the most important factor to a home garden success.

Coneflower, also known as the purple coneflower, is a very versatile perennial plant. The plants grow 3 to 4 feet tall and grow in clumps that spread about 2 to 4 inches every year. Leaves on this plant are somewhat fuzzy and medium green in color. Coneflower blossoms are 2.5 or more inches across in diameter and resemble the look of daisies. The reddish-purple petals surround a rust-colored, black, brown or orange center. Flowers will begin to bloom around mid-summer and will continue to bloom for two to three months. Coneflowers prefer full sun and well-drained, moist soil.

The plant grows well in full sun or light shade and prefers a well-drained slightly acidic soil.
