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.

These red and green leaves have ruffled edges.

I took time to just enjoy my home landscape this last weekend. I put off chores just to take a look at some of my solid garden performers. Here’s what I observed. Coleus has become one of my go-to plants for looking great all summer and still going deep into the fall. Nobody can get bored with its kaleidoscope of colors and various leaf shapes.

Lately, I’ve been browsing through gardening social media pages, and I’ve noticed lots of questions about this shrub that seems to have appeared out of nowhere with its beautiful purple berries. I love when people notice our native Callicarpa americana for the first time. Its common name,  American beautyberry, makes sense once you have seen the plant.

My favorite plants for the fall season are crotons. These beauties have some of the boldest and brightest foliage found in garden centers. Their warm foliage colors of bright yellow, red and orange shades are perfect for autumnal decorations and displays

As I wrote this column, I also was watching the weather as Hurricane Ida aimed for the northern Gulf of Mexico. As such, I spent time in the garden picking and harvesting various crops that I don’t want to lose. One group of plants I harvested were my specialty peppers that I’ve been babying all through this hot and humid summer. I brought in both biquinho and aji charapita peppers.
