Low-growing annual and perennial plants make ideal plants for garden borders. A uniform border placed in the front of the garden creates elegant lines and designates a garden space. Just about any low-growing plant can be used as a border plant for the garden. Blooming plants attract butterflies and hummingbirds to the garden and add color, while evergreen plants usually have low maintenance requirements.
Daylilies are vigorous growers in most parts of the United States. They have grassy leaves and provide a steady show of flowers throughout the growing season. They can last for years if given proper moisture levels and provided plenty of organic matter in the soil around the roots. The color of flowers provided by the multitude of varieties available range from pink, purple and red to orange and yellow.
Nasturtiums provide bright orange, yellow and red flowers for a colorful annual border. In the southern United States, nasturtiums are planted in late winter because they can withstand a light freeze. In northern states, nasturtiums provide color all summer if planted several times times in succession. An added benefit is that nasturtium flowers are edible and have a spicy, peppery taste. However, do not eat flowers that have been exposed to pesticides.
Sedum is the name of a wide range of low-growing perennial succulents that provide texture and color to rock gardens and other dry garden areas. Some varieties grow up to 2 feet tall, but most varieties grow low, rarely reaching 6 inches in height. Some varieties produce flowers on stems long enough to be used as cut flowers.
Pansies are a common border or bedding plant throughout the United States. New varieties with larger flowers and vibrant colors become available in garden centers every year. In the southern United States, pansies are planted in the fall because they are one of the few plants, along with snapdragons, that provide color during the winter. When planted in a mass of the same color in a border, pansies make a dramatic statement in the garden.
Mondo grass, also known as monkey grass, is a very common border plant that remains green all year and is used throughout the United States as a border plant or ground cover. It forms a dense sod that is impenetrable to weeds and encroaching grasses. It grows to 8 inches high and has dark green grassy leaves. Some varieties produce a small blue, purple or pink bloom spike in the spring followed by dark blue berries in the fall. Mondo grass is suitable for shady locations.
