Travelers may bring Plumeria cuttings or small plants in their luggage for personal use, but there are limitations and regulations to consider. Plant material in luggage is subject to inspection by customs officials, and it must comply with USDA regulations and any state-specific requirements. Bringing live plants or cuttings on international flights requires proper packaging and documentation, such as a phytosanitary certificate, to demonstrate compliance with phytosanitary standards. It’s essential to declare the plants to customs upon arrival and be prepared to provide any necessary information about the imported Plumeria to avoid any issues during the customs inspection.
