Do Salvias grow back?

Many perennial Salvias will bloom twice if you do nothing, but if you dead-head them (remove the old, spent flowers) you can get three or even four blooms in a season. The first flush of bloom is the most robust, but the flowering will linger on all season if you give it a proper pruning after the first bloom.

Are all Salvias Hardy?

Salvias really earn their keep in the garden. Shrubby and hardy herbaceous salvias can be overwintered if they're given good drainage and as much sun as possible. In colder spots, tuberous half-hardy salvias, like Salvia patens, will need to be mulched or lifted, like dahlias.

How do you keep Salvias from flowering?

You have two options for deadheading salvia. Because the plant has thin stems, it can be deadheaded by hand using just your fingers. However, plucking the flower spikes by hand can prove tedious if you're growing many salvia plants. To save time, use handheld pruning shears instead.

Are you supposed to cut back lavender?

The best time to prune lavender is after flowering is complete, but this plant is forgiving. All lavenders bloom on the stems that grew in the current year. This means that pruning can be done in early- or mid-spring without sacrificing the current year's flowering.
