No, Philodendron hope and Philodendron xanadu are not the same plants. Philodendron hope is actually Thaumatophyllum bipinnatifidum, aka Philodendron selloum, aka Tree Philodendron. Both plants belong to the Araceae family, the Philodendron genus, and the Meconostigma subgenus, but they are separate species. The Hope Philodendron is taller and may reach 12 feet tall, whereas the Philodendron xanadu reaches no more than 5 feet in height. The Hope Philodendron has larger leaves and may develop into a tree, hence the name Tree Philodendron. On the other hand, the Philodendron xanadu grows in clumps.
