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.

While visiting my parents in Tennessee this weekend, my dad asked why one of their Annabelle hydrangeas was blooming while another -- growing just 5 feet away -- was not. He asked if I had some special fertilizer or bloom juice that could be applied.

I didn't, because the shrubs didn't need any special fertilizer help. It all had to with light.

How have we already turned the corner into August? While it’s still hot and likely to continue that way for at least another six weeks, I’m looking forward to one of my late-summer landscape favorites, the ornamental pepper.

These plants have been growing patiently all summer, seeming to wait patiently and soak up the Mississippi heat until our other plants need a breather. If you follow Southern Gardening, then you probably know that I really love the show that ornamental peppers put on in late summer and early fall.

Dozens of yellow flowers fill the frame.

The last few weeks have been hot and humid, and many of my gardening friends are ready for fall's cooler temperatures.

Dozens of red, yellow and white flowers grow on long stems.

Because of the oppressive heat and humidity in my coastal landscape and garden, I spent the weekend in the air conditioning, of course.
