Heat Tolerable plants

Cactus! That might be the only thing to survive at those temps!

I get that. I'm in Oklahoma with wind, heat, snow, we get it all. Rose of Sharon bushes are really sturdy. My go to are Day Lillies. They come back every year and bloom right after my iris'. They also come in several colors now. On top of that, they multiply on their own so you can thin them out and start a new garden.

You can find your Zone here:

Roses will do well. Agapanthus thrives in the sun. Texas privet. Hollyhocks, geranium. I have all of these and temps here are over 100° and sitting in the blazing sun.

Most native plants do well in heat . Coneflowers and yes Day lilies even my roses , however anything needs more water when first planted it took mine two years to establish but now need little water

in the 100 plus weather of the summer.

think agastache , salvias , zinnias , cosmos coreopsis , check to see what’s native for your area remember too most plants from home centers are under a shade cover they will heat stress without a bit of conditioning .

Depends what state your in. I'm in new Mexico so for me there's anything from yuccas, small blooming cactus, and yellow star jasmine vine. As the lady above said you can Google for your zone, it'll tell you just what you need.

I also go for only perennials as they come back 2 years and longer. Have fun.🙂

Bury a piece of sponge (dish sponge, old furniture cushion, whatever) under your plants. It will help keep them alive (and maybe even blooming) on the hottest days.

Are you planting next to the wall ? I would suggest planting flowering crepe myrtles in your yard. They bloom in the summer and would provide some shade where the wall could be a little cooler. The blooms come in colors of white, shades of pink, reds and purples. Good luck.

You could do a attractive succulent and rock garden. cant get any more maintanence free than that.

Growing lantana in the garden is a great way to add color and interest. Simply choose a sunny location and plant them in well-draining soil. Although these plants are tolerant of many soil conditions, lantana flowers prefer slightly acidic soil. They draw lots of butterflies. Come in several colors and mixed colors.
