Introduced as a houseplant around 1900, the red emerald is one of the most common vining types. Its leaves are rather long and narrow with yellow veins. It is a hybrid that is sought for its striking burgundy-red leaves. It can be propagated by taking cuttings at a joint and rooting in moist potting soil. As with all philodendrons, it is easy to care cor, preferring warmth and humidity. However, it does need to be staked or given support for climbing. Water-absorbent poles such as those made from wire and sphagnum moss are ideal. It has added environmental value, as it is a leader among the philodendrons in removing indoor air pollutants. Vining philodendrons, such as P. erubescens, are among the easiest houseplants to maintain.
