Shown below are plants that came from cuttings of a climbing Philodendron from my garden. Every morning at dawn when I work in my home office I look east out the window and see the morning light showing through this plants leaves. It’s so beautiful and such a delight to see. The plant in my garden has now climbed up about 25 feet on a King Palm trunk. Leaves are about 18 inches long and 12 inches wide mature. Leaf stems are red. I do not know the species name of this plant. I got it from an old time collector 40 years ago. I’ve only offered it for sale once or twice in the past forty years. The first photo shows the back of the leaf with light showing through a leaf. As it’s now nighttime while I’m writing this, I cannot take a photo of the mother plant.
I only have a handful of these available. It’s a spectacular companion plant.
