  • Posted by GoneTropical (Orlando, Florida - Zone 9b) on Jan 4, 2012 11:30 AM concerning plant:
    This cactus prefers to climb up trees, preferring oak or pine, clinging to the rough bark with its aerial roots.
    Blooming time in Florida lasts several weeks in midsummer. The huge, dinner plate sized flowers open around 10 pm and close before sunrise.
    In their native habitat bats are the pollinators.
