If you live where the dog days of summer seem endless, growing a beautiful garden probably seems like a waste of time. Who wants to watch their plants wilt and scorch in the hot sun, after all? Your garden will be happy to know that there are many perennials for hot areas that not only survive the hottest days of the year but thrive.

Landscaping Your Yard with Heat Tolerant Perennials
There is a wide range of popular plants that grow in dry climates and hot areas, and we chose some of our favorites. These tough-as-nails beauties are easy-growers that look fantastic year after year.
You may even consider adding some heat tolerant ferns in addition to your perennial plants for greater garden diversity and interest.
Which Plants Tolerate Hot Climates?
You can find many types of desert trees, as well as a variety of perennials that resist heat and love the sun. Not only do they tolerate tough conditions, but they also grow back each year with vibrant and colorful growth.
Durable plants such as salvia, sedum, and daylilies are ideal for challenging climates. They handle the hot rays of the sun with ease and dry soil with minimal problems.
The easiest way to know if your favorite plants handle high temperatures is to check the plant care tag. Look for keywords such as hardy, heat tolerant, and drought tolerant.
What are the Benefits of Landscaping with Perennials?
One of the top reasons for growing perennials is their ability to grow back every year. Annuals die at the season’s end, but perennials are growers that keep on giving.
Not only that, but each year’s growth is more beautiful and showy than the year before. Another benefit of growing a perennial garden is that they attract beneficial insects and birds to the yard.
Many of the flowers are a favorite among hummingbirds, butterflies, and honeybees. You get to enjoy the fragrance and color of your plants while watching the beautiful fluttering of pollinators.
Which Plants Should I Grow in a Summer Garden?
It all depends on the garden type you desire. If you have empty spaces where nothing seems to grow, consider planting low-maintenance ground cover plants such as stonecrop or blanket flowers.
If you have poor soil, try growing a rock garden filled with ornamental grasses and succulent plants. If you fancy a cut flower in your home, fill a flowerbed with coneflowers and yarrow.
