The above propagation data sourced from Claude AI
Pre-treatment: Cuttings are 15 cm in length, re-cut at the base, and terminal buds are removed. Cuttings are placed in a 2 minute fungicide bath. Cuttings are treated with 2000 ppm liquid IBA. Trim all cuttings to a 6- to 8-inch length. Remove all buds, leaves, and branches from the basal 2 to 3 in. of each cutting. Recut the base of each cutting at an angle and wound the basal end of the stem. Insert the base into rooting compound.
Establishment: Cuttings taken in June failed to root with the same treatment. Dormant semi-hardwood cuttings taken in early spring or fall give the highest rooting percentages. Cuttings collected at other times of the year may propagate as well or better.

ORGHPS Germination Guide: Requires light or the seed is very fine. Surface sow and expose to light. * sprinkle seed on 10 cm damp sphagnum moss; cover with clear plastic pop bottle cut in half; transplant seedling to acidic mix in shade outdoors when 5 cm high; protect from rodents and give protection in cold frame first winter
