Propagation is typically done via rooting hardwood cuttings taken from the plant in late fall or early winter. Cuttings should be 6-8 inches long and taken from stems that are 1-2 years old. Cuttings should be taken from the base of the plant, just above where new growth is beginning to emerge. The bottom leaves of the cutting should be removed and the cutting should be dipped in rooting hormone before being planted in a pot filled with a well-draining potting mix. The pot should be kept in a warm, brightly lit location and the soil kept moist. Cuttings should root within 4-8 weeks.
Usually, the plant growth rate average about 6 to 12 inches per year. Some of the newer hybrids are growing much faster with growth rates of 2 to 3 feet per year.
