Hoya is a genus composed of about 200 species in the family Apocynaceae. They can be found from India and China to Thailand, Malaysia, Philippines, Indonesia and Australia.
These slow growing plants have long, woody stems and fleshy leaves. Their flowers are sweet-scented and star-shaped, usually with five thick and waxy petals. They are perfect for hanging baskets or in a vertical garden.
The genus was named in honor of botanist Thomas Hoy (1750-1822).
The common name “Wax Plant” was given due to its waxy leaves and flowers.
Wax Plant symbolizes wealth and protection.
Hoya was earlier placed in the Asclepiadaceae family, commonly known as milkweed family. However, newer taxonomy placed the genus in the Apocynaceae family (dogbane family) which includes mostly tropical plants such as Carissa, Mandevilla, Nerium and Plumeria.
Hoya carnosa has the ability to remove pollutants from the air. It can reduce the components of indoor air pollution and make the air healthier to breathe.
