The above propagation data sourced from Claude AI
Pre-treatment: Cut plants into 6-8 inch lengths with at least 3 nodes per strand. Place about 3 strands in each pot filled 1/3 with well-drained potting mix. Rooting hormone may be used for certain species. Fill the rest of the pot with potting mix. Water daily and keep in a moist humid environment.
Establishment: Plants should only be propagated by cuttings due to the presence of the alien species and the hybridization of it with this species. Propagation by seeds cannot be done because of the hybridization problem. The plant is indigenous to Hawai'i and widespread in the Pacific.
