Propagation of Solenostemon sylvaticus (Gürke) Agnew
Solenostemon sylvaticus, commonly known as wild coleus, is a perennial plant native to Africa. Propagation of Solenostemon sylvaticus is typically done through stem cuttings. Stem cuttings allow production of an exact copy of the parent plant and is a quick and easy propagation method.
Stem Cutting Propagation

Cut a stem that is approximately 4-6 inches long with a clean, sharp cut. Remove the lower leaves from the stem to ensure that no leaves are buried in the soil. Dip the cut end in rooting hormone powder to stimulate root growth.
Place the cutting in a container with well-draining soil mix that has good moisture retention. Keep the soil consistently moist but not wet. Cover the pot with a plastic bag to increase humidity and reduce water loss. Place the container in a warm, brightly lit area with indirect sunlight. Keep the soil moist and allow the cutting to grow for several weeks until roots develop. After the roots have developed, remove the plastic bag and transplant the new plant into a larger pot or outdoors if the weather is warm enough.
