If you're looking for a plant to add vibrant color to your garden—without requiring a lot of care—red salvia might be the plant for you. To thrive, red salvia needs enough sunlight and well-draining soil. Beyond that, you will barely have to think of this eye-catching specimen, except when guests inevitably ask what that cool plant is.
To improve the look of your red salvia (and to encourage them to produce bountiful flowers), it's important to deadhead faded blooms. You can do this by pinching off the flower spikes that have finished blooming—make sure to pinch down to the bottom of the stems.

Red salvia can grow successfully in a spot that receives partial shade, but ultimately it will grow (and bloom) better the more hours of sun it receives. Strive to plant your salvia in a location that gets at least six to eight hours of bright sunlight per day.
