A hoya is a genus of flowering plants in the milkweed family, Apocynaceae. They are native to tropical and subtropical Asia, Australia, and the Pacific Islands. Hoyas are evergreen vines with fleshy leaves and waxy flowers. They are popular houseplants because they are relatively easy to care for and can tolerate a wide range of conditions.
Characteristics of Hoyas
Hoyas are characterized by their:
- Fleshy leaves: Hoya leaves are thick and succulent, which helps them to store water. This makes them drought tolerant and ideal for growing in areas with low rainfall.
- Waxy flowers: Hoya flowers are waxy and come in a variety of colors, including white, pink, red, and yellow. They are often fragrant and bloom in clusters.
- Vining habit: Hoyas are vines and can grow up to 20 feet long. They can be trained to grow on trellises, fences, or other structures.
Types of Hoyas
There are over 200 species of hoyas, but only a few are commonly grown as houseplants. Some of the most popular types of hoyas include:
- Hoya carnosa: This is the most common type of hoya and is often called the wax plant. It has thick, oval leaves and produces clusters of white or pink flowers.
- Hoya bella: This hoya has smaller leaves than Hoya carnosa and produces clusters of pink or red flowers.
- Hoya pubicalyx: This hoya has fuzzy leaves and produces clusters of white or yellow flowers.
- Hoya kerrii: This hoya is also known as the sweetheart plant because it has heart-shaped leaves. It produces clusters of white or pink flowers.
Care for Hoyas
Hoyas are relatively easy to care for and can tolerate a wide range of conditions. However, they do have some specific needs:
- Light: Hoyas prefer bright, indirect light. They can tolerate low light conditions, but they will not bloom as much.
- Water: Hoyas should be watered when the soil is dry to the touch. Avoid overwatering, as this can lead to root rot.
- Humidity: Hoyas prefer high humidity levels. They can be grown in a humidifier or on a pebble tray filled with water.
- Fertilizer: Hoyas should be fertilized monthly during the growing season. Use a balanced fertilizer diluted to half strength.
- Repotting: Hoyas should be repotted every 2-3 years. Use a well-draining potting mix.
