Perennial Flowering Plants in Mississippi

Perennials are plants that live for several years and often require two or more years from seed to flower. There is a renewed interest in herbaceous perennials because they need less maintenance, less water, and fewer pesticides than annuals. Many gardeners include flowering bulbs and ornamental grasses in this category. Once prominent in many landscapes, these enduring plants are being rediscovered for their dependable seasonal effects.

Unlike trees and woody shrubs, which are also perennials, herbaceous perennials are those that appear to die down part of the year, only to emerge again the following season from underground roots, stems, bulbs, or rhizomes. The simple term "perennial" is commonly used when referring to herbaceous perennials.

Many perennials are short bloomers and are best mixed with others that bloom at different times or included with other landscape plants as part of an overall design. Other perennial plants, such as ferns and monkey grass, are more noted for their foliage than their flowers. Inclusion of these plants adds interest and creates seasonal color or texture to the landscape.

Favorite perennials, including many herbs and native wildflowers, have long been shared by gardeners and sold through garden centers and mail-order nurseries. Many are treasured by gardeners as heirloom plants and have proven themselves to be hardy enough to withstand our weather and climate extremes, often with little care. Others are exciting new discoveries or hybrids and may take several years to prove themselves in Mississippi gardens. However, there are a good many perennial plants that simply do not survive for more than a year or two in our warm, humid climate, just as some of our favorites will not survive long in colder areas of the United States.

Most annuals are planted in spring and are killed by frost in the fall. However, some, including pansies, ornamental cabbage, and dill are tolerant of our winters and are best planted in the fall for color throughout the winter. These are usually killed by the heat of early summer.

Some annuals, such as gomphrena, cosmos, and coreopsis reseed themselves, yielding several years of pleasure with minimal care. Annuals come in a variety of colors, heights, and textures, and their uses are almost unlimited. Unbeatable in masses of solid or mixed colors, annuals are also very effective in small groups or used to soften lines and accent borders.

As we continue to plow through this hot and humid summer, keeping our plants -- and ourselves -- hydrated is critical to maintaining the summer garden and landscape. As I write this column, it's 96 degrees with a heat index of 108. Whew!

Like most gardeners, I love watching the various butterflies that visit my garden.

One I really like is the giant swallowtail, with its black body and vivid, yellow stripes. This creature loves my citrus, where she lays her eggs. The developing caterpillars have a unique defense mechanism; they look like bird poop on the citrus leaves.

Variegated burgundy and chartreuse coleus laves fill a container.​

Since we celebrated the first day of summer last week, I think this is the perfect time to talk about one my favorite color plants, the coleus.

Coleus used to be that colorful plant that would grow only in the shadows, never exposed to the sun. One of my favorites of this kind is the sun-bashful coleus group, Kong.
