Living in the South, I used to struggle with keeping my garden alive through our brutal summers.
That is, until I discovered these 10 incredible perennials.
These easy plants turned my ugly yard into the prettiest one in the neighborhood – and they basically take care of themselves!
Top 10 Perennials for Southern Gardens
1. Blanket Flower (Gaillardia x grandiflora)
Y’all, this might be my favorite low-maintenance superstar. In my front border, these tough native plants laugh in the face of our brutal summer heat.
The flowers burst with warm yellows, oranges, and reds that remind me of a gorgeous Southern sunset.
At just 1-2 feet tall and wide, they’re perfectly sized for any garden space. I’ve found that giving them full sun and well-drained soil is all they need to thrive.
Quick tip: I spend about 5 minutes deadheading spent blooms while sipping my morning coffee, and they reward me with continuous flowers until frost.
2. Black-Eyed Susan
These cheerful flowers are like little rays of sunshine in my garden, especially during the hottest days of summer.
They’ve become my go-to for filling empty spaces in borders and containers because they’re practically bulletproof in our climate.
Growing up to 3 feet tall and 2 feet wide, these beauties love our Southern sun and actually seem to perform better when the temperature soars.
3. Canna (Canna indica)
Want instant tropical vibes? My Cannas deliver dramatic flair without the drama of high maintenance.
The Pretoria variety is my absolute favorite, with its stunning variegated leaves that catch everyone’s eye.
These gorgeous giants can reach 7 feet tall while staying relatively slim at 2 feet wide, perfect for creating that vertical wow factor in any garden space.
4. Yellow Flag Iris (Iris pseudacorus)
If you’ve got a soggy spot in your garden like I did, this iris will become your best friend.
I planted mine near my garden’s drainage area, and it’s thrived there for years with those stunning yellow blooms brightening up spring.
The evergreen foliage keeps things looking lush all year long, reaching impressive heights of up to 5 feet while staying neat at 2 feet wide.
5. Japanese Sedge (Carex morrowii)
This is my secret weapon for those tricky shady spots where nothing else seems to grow.
I absolutely adore the Variegata variety, which adds stunning strips of cream and green to brighten up dark corners.
Standing 1-2 feet tall and wide, it forms these perfect little clumps that look gorgeous year-round with zero fuss.
6. Obedient Plant (Physostegia virginiana)
Don’t let the name fool you – this native beauty has a mind of its own, but that’s what I love about it!
The snapdragon-like flower spikes appear in late summer just when my garden needs a fresh burst of color.
At 4 feet tall and wide, it’s perfect for filling larger spaces, and I’ve found it thrives in both sunny spots and partial shade in my garden.
7. Crinum Lily (Crinum americanum)
Let me tell you about this Southern belle of the garden – my Crinum lilies are absolute show-stoppers.
Their fragrant clusters of pink, purple, or white flowers keep my garden looking elegant from spring through fall.
At a manageable 2 feet tall and wide, they’re the perfect middle-ground plants in any garden design.
8. Southern Shield Fern (Dryopteris ludoviciana)
This fern has been my saving grace in the woodland area under my old oak tree.
It’s the perfect solution for those challenging shady spots, bringing life to areas where other plants struggle.
Growing 2 feet tall and spreading to 3 feet wide, it creates this gorgeous, natural-looking groundcover that requires virtually no maintenance.
9. Cast Iron Plant (Aspidistra elatior)
True to its name, this plant is practically indestructible – believe me, I’ve tested its limits!
It’s my go-to choice for those impossible deep shade areas where nothing else survives.
At 2 feet in both height and width, it maintains a tidy appearance year-round with minimal intervention.
10. Phlox
The sweet fragrance of my phlox on warm summer evenings is absolutely intoxicating.
These 3-foot-tall beauties have become a favorite gathering spot for butterflies and bees in my garden.
I love cutting a few stems to bring that lovely scent indoors, and they keep blooming reliably throughout the season.

I can’t tell you how much time these plants have saved me in the garden.
Once established, they practically take care of themselves while providing non-stop color and interest.
These tough plants handle our Southern heat and humidity like champions, and there’s a perfect option for every spot in your garden, from deep shade to full sun.
The variety of heights and widths means you can create beautiful layered looks without spending hours on maintenance.
