You just brought home a pineapple sage plant but you would like a couple more. You could go back and purchase more plants. Or you could start them from cuttings you take from the one you already brought home. Prepare a 3” pot with moist soilless mix. Take a 4” cutting from the top of the plant using a sharp knife. Remove the bottom two leaves and stick the cutting into a hole you’ve made in the soilless mix. Firm the soil around the plant. Put the plant in a plastic bag held above the cutting by a clean plant marker or plastic spoon. Seal the bag and put it under fluorescent lights or on a northern windowsill or a very bright spot. Do not let the sun hit the bag or it will cook. When your cutting has rooted, gradually remove the plastic bag and give it more light. If it wilts, reseal the bag and wait a few more days. When it has developed a good root ball, gradually harden the plant off outdoors before planting in the herb garden.
