Most Philodendron will flower in 10 to 12 feet, sometimes less. I have a very large Philodendron sagittifolium (2.5 foot blades) that produces inflorescences just 6 feet from the soil every May and a couple of my terrestrial species produce an inflorescence just 2 feet above the ground. The majority of climbing Philodendron species don't necessarily have to drop at all other than Philodendron hederaceum.
