Unlike annual salvias, which will not return the following year, perennial salvias should show new growth each year. However, many factors can affect their timing. Are these established plants? If so, look for them to start new growth around the same time as last year, although certain stresses may cause delays. Is there any sign of damage to the two plants, from overwintering, animals, or disease/insects? If not, your salvias likely should start growth by mid to late May, but this can depend on species—some emerge later than others. A period of warmer weather may help to wake them up. For more information about how salvias are emerging in your area, you might try contacting a local garden center or your county’s Cooperative Extension—contact information can be found here:
