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.

The weather to start 2018 has certainly been crazy. We had more than a week of temperatures in the mid-20s (Freezemageddon) followed by a week of moderate, more normal January temperatures. Now, we’re freezing again this week.

What a crazy week we had to start off 2018 as “Freeze-mageddon” came blowing through with several nights of temperatures in the 20s or worse across the state.

I’ve been hearing and reading comments about the extreme cold we’re experiencing and how unusual it is. But to tell you the truth, these temperatures are not that unusual.

Mississippi gardeners who plan to incorporate more pollinator plants into their landscapes can consider native milkweed and begin gathering seed for indoor propagation.

As gardeners make New Year’s resolutions for their landscapes in 2018, I want to encourage all of them to resolve to correctly prune crape myrtles from this day forward.

In the current vernacular, severe pruning of crape myrtles is called “crape murder,” reflecting the seemingly random nature of the pruning cuts. To me, this type of pruning is very unattractive in the landscape.

For the last Southern Gardening column of 2017, I want to take a look back at some of my absolute favorite plants from my home landscape this past year.

I have been talking for several years about what fantastic garden performers Supertunias are. But my absolute favorite -- and it has been my favorite for several years -- is Supertunia Vista Bubblegum. This plant is so reliable it was chosen as a Mississippi Medallion winner in 2012.
