15 Classic Southern Flowering Perennial Plants

15 Classic Southern Flowering Perennial Plants

Finding out which plants thrive in our garden is a lifelong commitment. As you may have not figured out yet, it takes about 3 years or so for a perennial to “settle in” and perform the way it’s supposed to. The plant you’re buying may not look exactly like the picture you see on the tag in its first year. 

Gardening and plants that are trending now, may not be popular a year from now, but there are mainstays that we can always depend on to bless us with foliage or flowers. Tried and true plants that people will never get tired of.

I’ve put together a list of hardy plants and some of them that are like Southern Icons. Most of these plants invoke memories of your childhood home or Grandma’s house. The smell alone of a few of them may bring back vivid memories of years gone by, back to a quieter more peaceful time.

 Lots of the plants I am trying to incorporate in my garden are transplants or cuttings from the area’s I lived in as a child. Filling your garden with heirlooms and gifts from friends and family is a great way to hang on to your happy times.

As you travel around, keep an eye out for these plants or variations of the species and you’ll see why so many people continue to incorporate them into their gardens again and again.

With its billowy blooms swaying in the wind, the Bridal Wreath Spirea is a lovely addition to any garden. It gets its name from the bouquet like clusters of tiny flowers that bloom along its long stems. Spirea are deciduous shrubs that depending on variety will bloom in spring or fall.

Sweet Olive Tree

Sweet Olive Tree

These are evergreen shrubs that begin to bloom in early fall and have a sweet citrus smell like orange blossoms. They can be planted along walkways or driveways to create a privacy hedge or border that fills your yard with this heavenly scent. I have seen one about 20 feet tall although I don’t know how old it is.

Silverberry

Silverberry

Okay so most of you may know this as Eleagnus, a fast growing invasive border plant. The way I discovered this shrub was by smelling it in the nursery. In the fall, its will begin blooming with tiny white perfumey scented flowers that resemble small bells. Later in the season they bear a small sweet fruit that can be enjoyed by wildlife. You can totally eat it as well but they are very small. The new leaves have a silvery tint to them on one side and turn greenish grey as they mature. They grow very quickly and are beyond easy to grow.

Crepe Myrtle

Crepe Myrtles are everywhere here in the south. Lining driveways, streets and parking lots. Their beauty comes in many forms and colors. Their delicate blossoms resembling crinkled up crepe paper, range in colors including white, many shades of pink, red and deep purple. Even when they lose their leaves in the Fall, their bark and the smooth texture of the trunks and limbs has a pristine beauty to it.  Easy to grow and care for, these flowering trees come in many colors and sizes to fit any landscape design.

Hydrangea

Few plants can rival the old-fashioned charm of hydrangeas. Their showy blooms can go from Spring to Fall in some varieties. Magnificent mophead, tall narrow panicle, and lace cap are some of the varieties. Blooms range in shades from White to Dark Purple, Blue, bright red and even green. No matter the color, their blooms are always a show-stopper in the landscape.

There are different types and sizes that can fill most any spot or condition in the garden. Some are bred to be smaller than three feet, while some grow larger than eight foot tall. There are even vining ones!  They grow well in damp areas, some in full sun and many varieties do even better in the shade. With more varieties being introduced by growers every year, you are sure to find one just right to brighten your backyard.

Canna Lilies

Canna lily are a very common plant in most gardens around the south. They are easy to grow, and tend to naturalize very quickly on their own. Bright red, orange, or yellow flowers depending on your variety, emerge from the tall slender stems throughout the summer. Like all these plants, they flourish in the humid southern heat and require little care. They enjoy a damp area but will tolerate many different types of soil.

Canna lilies have their quirks though but if you can learn to overcome them, they are definitely a tropical beauty to add to the landscape. They can be prone to Canna Leaf Rollers, a caterpillar that can do heavy damage quickly to a mass of plantings. Click here to learn how to avoid these nasty caterpillars.

Jasmine

The scent of jasmine in the air and the bright white flowers blooming in the warm evening of Summer evoke memories of old New Orleans. These vining perennials are a huge favorite in the south and are used to decorate trellis’s and fences as well as gates and arbors.

Jasmine can be grown in a pot or hanging basket but are usually planted in the ground and trained to cover garden structures. Jasmine grows well in full sun to partially shaded areas and most varieties are evergreen and will flower most of the year and fill your yard with that heavenly scent.
