Thankfully, there are quite a few drought-tolerant, flowering plants that do well with both the heat and cold for those of us who want a beautiful, fuss-free landscape filled with colorful plants.
I shared 10 of my favorite cold and heat tolerant, flowering plants in my latest article for Houzz.
Hopefully, you will find some new favorites to try in your own garden.
