A climbing vine, native to the northern states of S America, where it grows up and along the trunks and branches of tropical forest trees. The juvenile form has green heart-shaped leaves, heavily marked between the veins with silver. The adult form has larger, all green, heart shaped foliage to 30cm long. The silver variegation of the juvenile form makes it attractive to grow as a houseplant. In habitat, the adult foliage is only produced once the plant has grown high into the tree’s canopy. Greenish purple spathes are produced on mature plants

How to Grow

Cultivation

Under glass, grow in well-drained, ericaceous, loam-based, peat free, potting compost, mixing in some extra perlite, choosing a position in bright but diffused light. During the growing season, April to September, allow the surface of the compost to become just dry before thoroughly watering the compost. Avoid plants sitting in water which can cause the roots to rot. Apply a liquid houseplant fertiliser monthly. Water less frequently in winter, when growth slows right down, and stop feeding at this time until the spring. Repot every 2-3 years. See Philodendron and houseplant cultivation for further advice
