The 15 Best Flowering Shrubs For Your Southern Garden

16 de januar de 2024

Hydrangeas are a Southern garden staple so universally loved that no one dares question even a single cluster of baby-blue blooms, even if they’re merely there to flank your trash cans. Hydrangeas are just a non-negotiable—unless of course, you’re ready to venture outside the cluster of baby-blue blooms. There lies a whole host of other flowering shrubs and plants out there that can fill your garden with all the color and curb appeal you could dream of, with space to spare for a bush or two of hydrangeas if you still so please.

We’ve got suggestions that include classic show-stoppers like the pink lady, azalea, and intoxicatingly fragrant gardenia, along with other options that look like a million bucks on your lawn. Keep your hydrangeas and add these 15 flowering shrubs to your Southern garden for the ultimate explosion of color.

Azalea

One of the South’s favorite shrubs, azaleas offer some of the best curb appeal potential of all these flowering staples, which is why you’ll see so many blooming in Southern gardens from spring to fall, depending on the variety. When choosing the best spot to plant, know that azaleas like plenty of morning light, but you might want to avoid areas that get midday or hot afternoon full sun. When planting in masses, use the same selection in the same hue for maximum impact. Azaleas range in size depending on the variety—make sure to check maturity size and spacing requirements before planting to prevent large selections, like Southern Indian hybrids that can grow up to 8- to 10-feet tall, overtaking a sizable section of your landscape.

Botanical Name: Rhododendron spp.
Sun Exposure: Filtered sun, Part sun
Soil Type: Light, Well-draining

Gardenia

White Gardenia Flowers

This tender white flowering shrub makes any garden look classic and timeless. Not to mention, it boasts some hard-to-resist attributes: beautiful evergreen leaves, snow-white blossoms, an intoxicating fragrance, and the ability to withstand the Southern summer heat. Gardenias bloom in spring and summer and individual flowers can last several weeks in bloom. Plant gardenias where they can get 4 to 6 hours of sunlight—in warmer climates, they’ll prefer morning to mid-way sun with afternoon shade, in cooler climates, they can grow in full sun. These tropical evergreen shrubs grow in USDA Zones 8-11 but there are now many varieties tolerant to cooler temperatures that can be grown in Zone 7, such as «Kleim’s Hardy» and «Frostproof».

Rhododendron

Blue Ensign Rhodedendrons

Big-flowered rhododendrons are a beauty to behold, especially considering you don’t see them nearly as often as other classics like hydrangeas. Why? Because sadly, they are more finicky to grow in the South. (Experienced gardeners will like the challenge.) If you take the chance, you might just have the showiest shrubs on the whole street. Rhododendrons needs dappled light to light shade and well-draining, moist, acidic soil that’s organically-rich, but the biggest challenge is that they don’t like heat. For Southern gardens, there are some heat-tolerant selections that can grow in USDA Zone 8 such as «Album Elegans», «Anna Rose Whitney», «Caroline», «Chionoides», «Lee’s Dark Purple», «Nova Zembla», «Roseum Elegans», «Vulcan», and the Southgate hybrid series.
