This diverse group of plants ranges from vines with 3-inch heart shaped green leaves to vines with leaves 3 feet long. Some types have glossy solid green leaves, others have velvet textured patterned leaves, while some have deep red leaves and stems.
While the most common types of philodendrons are vining, some are self-heading. Self-headers send out leaves from a heavy clump of growth at their base. These often have dramatically large leaves in a variety of shapes.
Most philodendrons prefer indirect or curtain-filtered sunlight but will tolerate low light. The common heartleaf philodendron (Philodendron scandens) will tolerate very low light.
Water frequently enough to keep the soil evenly moist, but not soggy. Never let the plants stand in water. High humidity is ideal for best growth, but philodendrons tolerate the low level of humidity in most homes.
Fertilize philodendrons regularly with a dilute water-soluble houseplant fertilizer, or use a time-release fertilizer.
