Hoya varieties are popular, easy-care, vining plants which bear spectacular clusters of star-shaped, fragrant flowers and fleshy leaves.
There are over 500 species of Hoya Plants which belong to the family Apocynaceae (Dogbane) family and are native to the tropical regions of Asia with many species also found in Australia.
Hoya Plants are referred to by many sommon names like Waxplant, Waxvine, Waxflower, Porcelainflower or simply Hoya. The Hoya genus was named by botanist Robert Brown, in honour of his friend, botanist Thomas Hoy.
Most Hoyas grow epiphytically on trees while some grow terrestrially or occasionally in rocky areas. They climb by twining with their adventitious roots.
Hoya flowers appear in clusters at the tip of peduncles which are commonly referred to as spurs. The spurs are perennial and are rarely shed as new flowers are borne on the previous year's spurs. The length of the spur increases with each flowering cycle.
The leaves in Hoya Plants are simple entire, arranged in an opposite pattern and are typically succulent. They may exhibit a variety of forms and may be smooth, felted or hairy.
The leaf venation in Hoya varieties may be prominent or not. Many species have leaf surfaces flecked with irregular small silvery spots.
Below is our selected list of Hoya Varieties that you can grow in your home.
