Red, Salvia darcyi, survived well through the desert winter months that hit in the mid 30’s and does superb in the high heat as long as it is watered everyday! It is a thirsty plant during these temperatures of 100 degrees or more. I recommend larger pots than the ones I used.
This is by far the MOST hardy, successful flower in my Arizona Garden! This perennial Salvia will generally grow from between eighteen inches and thirty-six inches, yet there are some that are much smaller. Mine is averaging about 20 -22 inches. The red salvia in the picture is a young plant that actually started from a fallen seed. The photo above is just after I pruned the finished red flowers. From having Salvia (red and blue) for over 2 years now I have learned it is best to trim them quite far down the stem to gain a thicker shrub. Best of all this flowering plant is critter proof. Last year the desert rats, squirrels, and rabbits ate most of our flowers except the Salvia. Since then, we are determined to have a rat-proof, squirrel-proof, rabbit-proof thriving Garden. Quick note:Hummingbirds love the flowers and will visit your garden often!
To keep your Salvia looking vibrant and encourage better flowering, deadhead the plant. You can do this by pinching or cutting off the flower spikes with spent blooms, I like to use small pruning shears.
Red salvia flowers can form a striking border when massed together. It is a good choice for a bedding plant. Some people call this perfect Arizona plant, Scarlet Sage.
