The Monstera Peru Karstenianum (also known as the Monstera 'Peru', Monstera Karstenianum, Epipremnum Pinnatum 'Marble Planet', Philodendron Karstenianum and Philodendron Opacum) is an aroid that enjoys bright indirect sun. Shes probably not Peruvian and may not even be a Monstera, rather she is likely a Philodendron native to the rainforests of Venezuela, but the scientists are still catching up on this one. The Monstera Karstenianum will grow well in household humidity and loves rich and well-draining soil (like a mixture of orchid bark, perlite, and peat).
