Mine is Araceae, the aroids. I love this family because it encompasses so many genuses that have such great diversity of species. Alocasia, colocasia, anthurium, philodendron, monstera, rhaphidophora, tetrosperma, anchomanes, amorphophallus....so many more! Where else can you find two plants in the same Genus that look so different, like these? Rhaphidophora decursiva, the large growing vining beauty of the large leaf tropical; and Rhaphidophora korthalsii, the small vining shingler? Or Monstera deliciosa variegata and Monstera dubia, another shingler?
