Phaius is a genus of orchid, native to tropical climates and popular as houseplants. The most common type is the Phaius tankervilliae. It both produces flowers and is easy to care for.

There are over 20 different species in the genus Phaius, the majority of which are terrestrial orchids, meaning their roots grow in the ground. Phaius orchids grow a tall spike that produces brilliant, colorful flowers, and the plants have thick and distinctly veined leaves. Phaius are able to reach 3 feet (0.91 meters) tall, making them a striking plant in any greenhouse or garden. These orchids are native to tropical areas in Asia including China and Japan and can also be found in Australia, Africa and even Madagascar.

To grow Phaius as a houseplant, it is suggested that they be kept in filtered sunlight, as direct sunlight may cause the plant’s leaves to burn. They need to be watered often, yet it is necessary for the plant to be potted in soil with good drainage so its roots will not soak. The ideal potting soil is hummus-rich and contains fertilizers such as cow manure. Feeding the plant with orchid fertilizer, especially during the growing season of April through August, is recommended. They can even be grown outside in a garden bed in a tropical area. They thrive in temperatures between 60 to 70 degrees Fahrenheit (16 to 24 degrees Celsius) and can tolerate temperatures ranging from 40 to 95 degrees Fahrenheit (10 to 32 degrees Celsius).

The most common species of this plant is the Phaius tankervilliae. Originally native to China, it was first cultivated in the West in the late 1800s. It is considered to be easy to care for, making it a popular houseplant. Also known as the veiled orchid or the nun’s orchid, inside the flower’s tube, also known as the “throat,” it looks as though a covered head is bowing in prayer. In Australia, the Phaius tankervilliae is listed as being at high risk for becoming extinct in the wild.

The Phaius tankervilliae produces flowers in a variety of colors, including maroon, yellow, red, white, purple and even brown. These brilliant flowers can grow over 4 inches (10.15 centimeters) in diameter, while the plant’s stalk may reach over 4 feet tall (1.22 meters). The flowers have 4 petals, which are usually colored on the inside and white or a light color on the outside, while the central part of the flower is an open tube.

Frequently Asked Questions

What is Phaius and where can it be found?

Phaius is a genus of terrestrial orchids that encompasses around 30 to 50 species. These orchids are native to diverse regions, including Asia, Australia, Africa, and the Pacific Islands. They thrive in a variety of habitats, from lowland tropical forests to higher altitude grasslands, showcasing their adaptability to different environmental conditions.

How do you identify a Phaius orchid?

Phaius orchids can be identified by their large, showy flowers which often come in shades of white, yellow, red, or purple. They have a distinctive tubular lip, which is often brightly colored and serves to attract pollinators. The leaves are typically broad and pleated, emanating from a central pseudobulb, a storage organ for water and nutrients.

What are the ideal growing conditions for Phaius orchids?

Phaius orchids prefer warm, humid conditions with moderate to bright indirect light. They thrive in well-draining soil rich in organic matter. These orchids require consistent moisture but should not be waterlogged. A temperature range between 60-80°F (15-27°C) is ideal, with a slight drop at night to mimic their natural environment.

How often do Phaius orchids bloom and for how long?

Phaius orchids typically bloom once a year, with the flowering season varying depending on the species and growing conditions. The blooms can last for several weeks, providing a long-lasting display of color. Proper care and favorable conditions can encourage the orchid to produce multiple flower spikes during its blooming period.

Can Phaius orchids be grown indoors?

Yes, Phaius orchids can be successfully grown indoors provided they receive adequate care. They need sufficient indirect sunlight, high humidity levels which can be maintained through regular misting or a humidifier, and good air circulation. Indoor growers should also be mindful of temperature requirements and avoid placing the orchids in drafty areas.

Are Phaius orchids endangered?

Some species of Phaius orchids are considered endangered due to habitat loss and over-collection. Conservation efforts are in place to protect these species in their natural habitats. Orchid enthusiasts are encouraged to purchase plants from reputable nurseries that propagate orchids responsibly, rather than collecting from the wild.
