Annual Flowering Plants in Mississippi

No other group of flowering plants provides as much color as quickly and economically as annuals. Annual plants sprout from seed, flower, set seed, and die within one season. Many flowers, vegetables, and herbs are planted every year as annuals. Other plants may live longer in their native lands, but do not survive the heat or cold of the mid-south and are best treated as annuals.

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.

Columbines, such as this Aquilegia Swan blue and white, can thrive in Mississippi landscapes when treated as an annual.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.

Many annuals, especially compact varieties, are well suited for containers. Large annuals may be used as specimen or accent plants along the back of a flower or shrub border. Some annuals are vines that may be grown on fences, arbors, porch rails, or trellises.

Annuals are inexpensive, especially when grown from seed. However, they do require soil preparation, fertilization, irrigation, weeding, and pest control. Most are native to semiarid regions of the world and require full sunshine to survive.

Species such as impatiens are native to dark woodland floors and flourish in shady sites, such as covered patios, narrow courtyards, or heavily wooded sites.

Annual gardens are easily established in the smallest and most restrictive of spaces as well as the harsh conditions of a large suburban garden. Their relatively shallow root systems require only a modest amount of soil. Gardeners with sizable yards quickly learn the trick of planting one or two easy-to-grow beds of massed annuals to decorate patios, walks, or pools. Apartment dwellers can achieve a splash of color with a few well-placed pots, wash tubs, or planter boxes of annuals.

Annuals that need full sun, such as periwinkle and marigold, grow and flower best when they receive at least 4 to 6 hours of direct sunlight each day. Woodland species perform best under partial to heavy shade.

Prevent root diseases and other problems associated with waterlogged soil by avoiding areas where water stands after a heavy rain. Also avoid areas near large trees and shrubs that may have many greedy, thirsty feeder roots.

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.
