Winter Color / Salvia

I have two beds in the back yard.

They have fig ivy in them which grows year round. In the summer (we are in Dallas, Zone 7b, killer direct sunlight) I grow sweet potato vine over the fig ivy, and it prevents it from getting burned out. Also, there is red, purple, and white salvia interspersed amongst the vines.

I will be removing the sweetpotato vine and planting some cyclamen and pansies, maybe some ornamental kale. The question is this:

I recall either deadheading or "pulling" the salvia, but that it came back this summer. What is the preferred method, so that I can have the salvia come back again next summer when I re-plant the sweet potato vine?

Thanks

Don't pull up the Salvia or it won't come back next year. You can cut it back within inches from the ground though.
If you want to have more plants in other areas, when you prune it, take some of the stems and root them. Remove the flowering ends and put them in real moist potting soil and keep in the shade. If you use rooting hormone it will give them a boost to start rooting also. You can over winter the small plants inside, and plant them outside in the spring.
