Monstera Peru and monstera siltepecana are sometimes mistaken for one another, but there are two techniques to tell them apart. Because of its silvery sheen, the name "silver monstera" was coined, whereas the monstera Peru has dark green leaves. Second, the Monstera Peru has leaves with deep ridges, whereas the siltepecana monstera has leaves that are more flat. Fenestrations in mature monstera siltepecana leaves are more common than in monstera Peru, therefore it's worth noting.
