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.

Home gardeners in Mississippi need colorful plants that hold up to the hot conditions we have every year. One group of plants that is a great choice for summer color is salvia, which includes both perennial and annual top performers.

The annual Salvia Splendens, as the name suggests, can't be beat. It is commonly called scarlet salvia, but it comes in a variety of bright colors.

Christine Coker, a horticulture specialist with Mississippi State University, began sowing the seeds for her career in elementary school as a 4-H member. Now, she helps put food on Mississippians’ tables with her research and Extension projects.

BEAUMONT, Miss. -- For 16 years, Christine Coker has been doing what she loves: putting food on people's tables.

"In college, I really liked the study of plants, but I knew I wasn't going to be the world's greatest botanist," she said. "What I really wanted to do was feed people."

I really like to the flowering annual purslane in our hot summer landscapes. It's a vigorous, low-growing plant that forms a colorful carpet with succulent foliage.

But I plan to write about that wonderful plant in the future. Today, I want to extoll the virtues of one of its cousins: moss rose.

Moss rose has fleshy, succulent foliage that helps it hold up to the summer heat. The 1-inch-long, cylindrical foliage is bright green and arranged in clusters on the stems.

VICKSBURG, Miss. -- The Southern Gardener, Gary Bachman, would like to see Mississippi's historic bed and breakfast owners step up their game in the garden.

"What is your budget for your landscape and labor costs? Do you serve anything you grow and use your own flowers?" Bachman asked owners at a recent Mississippi State University Extension Service workshop. "I want to show you how, with minimal effort and minimal out-of-pocket expense, you can get a good return on investment from the landscape of your historic properties."

With summer officially here and hot and humid weather firmly in place, many gardeners -- myself included -- like to look at a pretty landscape, but don't really want to get out and do much work in that same landscape.

So selecting plants that look good without much work pique my interest. One plant that doesn't disappoint me is Sun coleus.
