Propagation of Salvia dorrii (Kellogg) Abrams ssp. dorrii
Salvia dorrii (Kellogg) Abrams ssp. dorrii, commonly known as the purple sage or Dorrii sage, is a woody perennial shrub that can grow up to 4 feet tall and 5 feet wide. This plant is native to the western region of North America. Propagation of Salvia dorrii can be done through different methods, including seeds, stem cuttings, and layering.
Propagation by seeds
Propagation through seeds is the most common way of growing Salvia dorrii. The seeds require a well-drained soil mixture with a pH of 6.5 to 7.0. Sow the seeds on the surface of the soil, then cover them with a thin layer of soil. Ensure that the soil is moist and not too wet to prevent rotting. The ideal temperature for germination is between 65 to 70°F.
Propagation by cuttings
Stem cuttings can also be used to propagate Salvia dorrii. Cuttings should be taken during the spring or summer. Use sharp, sterilized scissors or pruning shears to cut a 4-6 inch section of the stem. Cut just below a node, then remove the bottom leaves. Dip the cut stem in rooting hormone, then plant it in a well-drained soil mixture. Keep the soil moist and maintain a temperature of 70 to 75°F. Rooting should occur within six to eight weeks.
Propagation by layering
Layering is another way of propagating Salvia dorrii. Choose a healthy stem, then make a shallow cut halfway through the stem where it touches the soil. Bury the cut section a few inches deep in the soil. Mulch to maintain moisture levels and keep the soil warm. After a few weeks, roots should form at the cut section. Cut the stem and transplant the new plant to a new location.
