The Nephthytis, sometimes known as arrowhead vine, is a native of Mexico and Costa Rica and one of the easiest houseplants you can live and learn with. There are several species available on the market. They grow well as potted plants or in water.
The gentle Nephthytis or arrowhead vine is perfect for a beginner.
- They tolerate lower light levels as well as some direct morning sun. Near or in a north or east facing window, or a few feet away from a south or west window should easily satisfy this plant.
- It's a good idea to prune or pinch back some of the vines, from time to time, to keep a neat, fuller looking plant. The cuttings you remove will root very easily in water, so you can start and share new plants.
- A thorough soak is best each time you water them.
- For small plants, water as soon as the top of the soil is dry.
- In pots over 6" (15 cm) in diameter, water when the top of the soil is quite dry or up to 1/2" (2 cm) below the soil surface.
- A plant in a 6" (or15cm) diameter pot should take about a pint or half liter of water.
- A plant in an 8" (or 20cm) diameter pot will take about one quart or close to a liter of water. (The Nephthytis in the top picture is in an 8" pot.)
- Regular fertilizing helps them thrive. If you have your plant in water, when you mix up plant food for your other plants, pour a little into the vase or container of Nephthytis.
