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.

Many of Mississippi’s perennial landscape plants will start to decline after several years. That means they will have smaller foliage and won’t flower as much, even though they’ve been well cared for with regular fertilizer and irrigation.

It’s no secret that I’m a real fan of salvia. A couple of weeks ago, I enjoyed highlighting sage, which is a great culinary salvia. This week I’m going talk about perennial salvia, another group of these great plants.

If you read this Southern Gardening column frequently, you realize that I grow much more than pretty flowers in my home garden. Besides ornamental plants, I love to grow vegetables that my wife and I can enjoy for dinner.

Salvia is one of the groups of plants that everyone should have in their landscape. This plant group has flowers with a wide-ranging color palette and different sizes. Salvias are loved -- by me especially -- because of their ability to attract pollinators, butterflies and hummingbirds.
