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.

Two hydrangeas are pictured in the foreground of a garden, with one blooming and the smaller one not blooming.

While visiting my parents in Tennessee this weekend, my dad asked why one of their Annabelle hydrangeas was blooming while another -- growing just 5 feet away -- was not. He asked if I had some special fertilizer or bloom juice that could be applied.

I didn't, because the shrubs didn't need any special fertilizer help. It all had to with light.

Several red pepper and a few yellow ones rise above green foliage.

How have we already turned the corner into August? While it’s still hot and likely to continue that way for at least another six weeks, I’m looking forward to one of my late-summer landscape favorites, the ornamental pepper.

These plants have been growing patiently all summer, seeming to wait patiently and soak up the Mississippi heat until our other plants need a breather. If you follow Southern Gardening, then you probably know that I really love the show that ornamental peppers put on in late summer and early fall.

Dozens of yellow flowers fill the frame.

The last few weeks have been hot and humid, and many of my gardening friends are ready for fall's cooler temperatures.

Dozens of red, yellow and white flowers grow on long stems.

Because of the oppressive heat and humidity in my coastal landscape and garden, I spent the weekend in the air conditioning, of course.
