Perennial Flowering Plants in Mississippi

Perennials are plants that live for several years and often require two or more years from seed to flower. There is a renewed interest in herbaceous perennials because they need less maintenance, less water, and fewer pesticides than annuals. Many gardeners include flowering bulbs and ornamental grasses in this category. Once prominent in many landscapes, these enduring plants are being rediscovered for their dependable seasonal effects.

Unlike trees and woody shrubs, which are also perennials, herbaceous perennials are those that appear to die down part of the year, only to emerge again the following season from underground roots, stems, bulbs, or rhizomes. The simple term "perennial" is commonly used when referring to herbaceous perennials.

Many perennials are short bloomers and are best mixed with others that bloom at different times or included with other landscape plants as part of an overall design. Other perennial plants, such as ferns and monkey grass, are more noted for their foliage than their flowers. Inclusion of these plants adds interest and creates seasonal color or texture to the landscape.

Favorite perennials, including many herbs and native wildflowers, have long been shared by gardeners and sold through garden centers and mail-order nurseries. Many are treasured by gardeners as heirloom plants and have proven themselves to be hardy enough to withstand our weather and climate extremes, often with little care. Others are exciting new discoveries or hybrids and may take several years to prove themselves in Mississippi gardens. However, there are a good many perennial plants that simply do not survive for more than a year or two in our warm, humid climate, just as some of our favorites will not survive long in colder areas of the United States.

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.

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.

Orange vine flowers resembling black-eyed Susans straddle the top of a wooden gray fence.
Filed Under: Flower Gardens December 11, 2017

Most folks have poinsettias and entertaining on the agenda during the holidays, but for this week’s column, I want to highlight a plant that has been an outstanding performer for me all year.

It took this past weekend’s hard freeze to finally shut down my black-eyed Susan vine (I’m going to use the abbreviation BES for this flower), known botanically as Thunbergia alata. For many gardeners, in their experience this is traditionally a basket plant that deserves to be grown more often.

It seems like I've seen Christmas decorations in stores for at least a couple of months. They really accelerated after Halloween, completely ignoring Thanksgiving, which was when I noticed early poinsettias out in force.

Along with Black Friday, Small Business Saturday and Cyber Monday, the appearance of these poinsettias means we are in the full swing of the Christmas season.

In my opinion, the poinsettia is the quintessential Christmas plant. With its brightly colored bracts, it is a plant truly full of holiday cheer. I think most people will agree that the poinsettia is second only to the Christmas tree in essential Christmas season decor.

Celebrating Thanksgiving with family and friends got me thinking about traditions and beliefs, some popular in the distant past but gone by the wayside today.

In agriculture, some of the most popular myths revolve around the changing seasons.

Purple viola flowers grow in a container.

The last two weeks, I've told you about two of my top three cool-season flowering bedding plants. Today, I'm going to complete the trifecta with another plant everyone should have in their landscape: the viola.

Violas may have smaller flowers than their cousin, the pansy, but they're maybe even tougher and more tolerant of cold, winter weather than pansies. These plants are beautiful massed in landscape beds, and they can be great performers all the way to Easter.

Even though the air is still warm in many parts of Mississippi, it’s time to plant annual winter color. Last week, I wrote about pansies being a great color choice. Another sure-fire pick is dianthus.
