3-9 monthsPlant develops stronger vine growth, aerial roots appear and adhere to moss poles, leaves gradually increase in size
Mist regularly and maintain humidity above 60%. Support vining with moss pole or stakes. Feed monthly with diluted balanced fertilizer during growing season.
Mature Vegetative
Ongoing (mature phase)Large velvety leaves (8-12+ inches) with prominent white or pink veins fully develop; robust climbing growth with prominent aerial roots
Continue high humidity and bright indirect light. Prune aerial leaves and vines to control size as needed. Fertilize every 2-3 weeks during spring and summer.
Flowering (Rare Indoors)
Variable (2-4 weeks if it occurs)Produces small, inconspicuous greenish spadix flowers clustered within a spathe; rarely occurs in indoor conditions
