The above propagation data sourced from Claude AI

Pre-treatment: Tip cuttings, 5-7.6 cm in length, with multiple nodes of short intervals, 2-4 sets of leaves removed from base. Rooting hormone Dip 'n Grow IBA/NA at 20X dilution rate (1% Indole-3-butyric Acid; 0.5% 1-Naphthaleneacetic acid), 5 second dip. Cuttings stuck 2-3 per cell in 50 short plug tray 7.6 x 7.6 cm. Media: 2 parts Pro-Mix PGX, plug and germination media; 1 part coarse vermiculite (A4). Drenched with Essential Plus, biological root stimulant, immediately after sticking and at a 10 day interval. Neptunes Fish Emulsion applied at the recommended rate at signs of rooting.

Establishment: Cuttings collected December through May from greenhouse stock plants, flowering and non-flowing stems. 100% rooting obtained for cuttings taken between December and March. Native to North America, specifically to the southeastern United States.
