How to Propagate Coleus Amboinicus

Coleus amboinicus (Plectranthus amboinicus) is known as suganda in the Phillipines, where the leaves are macerated and applied to burns. The herb is used to flavor meat dishes in Java. C. amboinicus grows 12 to 18 inches tall, with green leaves that carry a fragrance that can be described as a combination of eucalyptus and oregano. Grow C. amboinicus as you would garden coleus -- outdoors within zones 9a through 11 on the U.S. Department of Agriculture Hardiness Zone Map, or indoors in pots.

Instructions

    • 1

      Combine equal parts of vermiculite, perlite and peat moss and pour water over it until it is evenly moist.

    • 2

      Fill a 12-inch planting pot, to within 1 inch of the rim, with the planting medium.

    • 3

      Remove a 6-inch long stem from the Coleus amboinicus with a razor blade or sharp scissors.

    • 4

      Snap off all the leaves with the exception of the top two.

    • 5

      Dip the cut end of the stem into water and then into the rooting hormone. Immediately insert it into the planting medium to within 1/2 inch of the leaves.

    • 6

      Place the cutting in a brightly shaded area. Keep the soil moist at all times. Give the cutting a light tug after three weeks. If it meets with resistance, the Coleus amboinicus has rooted.
