Philodendron scandens Heart Leaf Philodendron1
Edward F. Gilman2
Introduction
Heart leaf philodendron is probably most often seen as a houseplant, its two- to three-inch-wide, solid green, heart shaped leaves and long, thin stems trailing out of a hanging basket (Fig. 1). Although well-suited to indoor use due to its ease of growth and very high tolerance of low light conditions, when allowed to grow outside heart leaf philodendron takes on a whole new appearance. Grown as a ground cover, it quickly covers a shady area with its lush, dark green growth. As the strong stems climb up a tree trunk or other vertical support, the leaves become larger, eventually reaching 12 inches or more in length. If desired, it may also be grown in a container or on a totem pole or other moisture-retentive support column.
