“Participating in the 2016 IPC helped deepen my passion for growing plumeria. Getting to meet other plumeria growers from all over the USA, Japan, and Thailand and to hear their advice, taught me so many things to succeed in growing my own plumeria collection here in San Diego. I can’t wait to attend the 2023 IPC!” (Kathy Bowman, California)
