The Philodendron Crassinervium is an evergreen perennial that is native to southeast Brazil and is even endemic (only found there and nowhere else). At first glance, it does not resemble a typical philodendron at all. Like most members of the Araceae family (Monsteras, Anthuriums, and Epiprenums), it is fairly simple to care for and has no unique needs except from its love of humidity, which is to be anticipated from a tropical plant. The Philodendron Crassinervium prefers direct light that is bright. The optimal location for it in your home will therefore be somewhere where there is enough ambient light but no direct sunlight that reaches its leaves. Before watering, always check that the top 2 or 3 inches of the soil mixture are dry; don’t use the watering can too quickly.
