How to Care for the Nephthytis Plant

By M.H. Dyer ; Updated September 21, 2017

One plant that will provide beautiful foliage in spite of occasional neglect is nephthytis, also known as the arrowhead philodendron or arrowhead vine. With its red-veined, arrow-shaped foliage, nephthytis is a distinctive houseplant that can grow and thrive for many years.

Put nephthytis in indirect sunlight, if possible, but avoid intense, direct sunlight. If the light is bright enough to read a newspaper, it's bright enough for nephthytis

Water nephthytis lightly once a week. Don't worry if the leaves get a bit wilted during hot weather, because they will bounce back with a little water. Feed nephthytis a water-soluble houseplant fertilizer twice a month, according to the directions on the label.

As nephthytis matures, install a trellis or a stake for it to climb on. Nephthytis is a slow grower, so you won't need to worry about this for at least a year. If the plant gets bigger than you like, cut back the stems.

Trim nephithytis if you prefer that it stay compact. If you want, put the cuttings in a jar of water to grow new plants.
