Blue Cloud Sage plants also are called Transylvanian Sage (Salvia transylvanica). They grow 2 to 3 feet tall in full sun to partial shade. The low-maintenance perennials are easy to grow in average soil types. Blue blooms appear in mid-summer to early fall. They tend to do the best in climates with cooler nights. Regular watering will promote repeat blooms through the summer and pruning will help the plant achieve its best health and shape.
Prune blue cloud sage plants after they flower, removing by hand dead flower blooms. This will extend the blooming period.
Remove unsightly leaves and stems from plants that appear floppy and lifeless, cutting the plant back to its best and healthiest foliage.
Remove cross or rubbing branches by cutting them off with shears. In addition, remove up to 2/3 of the length of suckers that are young, straight shoots growing in excess.
Keep your plants healthy by snipping off any leaves or stems that are wilted or dead. These are taking nourishment from the rest of the plant. Cut them with hand pruners where they meet healthy foliage.
Achieve a mounded shape by identifying lateral branches that are too long. Follow them inside the bulk of the bush and cut them where they meet other wood. This will hide the cut.
