Heartleaf philodendron has long, winding stems that can trail gracefully from a hanging basket or be trained up a support. Its three- to four-inch leaves are dark green and heart-shaped.
The toughest of all house plants, the heartleaf philodendron can take just about anything other than cold temperatures. This plant is all too often left to take care of itself, resulting in a skimpy look. It is much more attractive when pinched and pruned regularly.
