Hoya Varieties: Popular Types And Species Of Hoyas (2024)

Many of us remember the thick leaves and star-shaped flowers of the Hoya plant sitting in a window at grandma’s house.

The most common Hoya varieties and the one most often seen and grown as a houseplant isHoya carnosaandHoya carnosa variegata.

The thick, waxy oval-shaped leaves of green are rimmed with red and white. The waxen texture of the leaves earns it the nickname “variegated wax plant.”

Hoya Plant History

The popularity of the name “Hoya” hails from Thomas Hoy (17 – 1821), gardener to the Duke of Northumberland. Hoy was the first to bring this superb tropical plant into prominence.

Native to southern India, this plant is highly prized and the subject of legend.

Hoya plants are from the Asclepias (milkweed) family. They are found throughout eastern Asia and Australia.

The exact number of Hoya plant species is a mystery. Bailey’s Standard Cyclopedia of Horticulture estimated 100 species. Listed at the end of the article are over 550 recognized species.

Hoya Flowers Exquisite Creations

In baskets or a sunny window, the foliage of Hoya plants is unusually decorative. Their late spring and summer porcelain and flowers are highly prized.

Some consider Hoya blooms among the most exquisite creations of nature. They appear fashioned from ivory or porcelain, with glimmering centers of ruby and amethyst. The new flowers of Hoya carnosa carry a barely noticeable, delicate, elusive, sweet fragrance.

The waxen ball of five-pointed double stars is geometrically perfect. This gives the Hoya plant bloom an artificial look. Those experiencing Hoya carnosa for the first time are pleasantly surprised to find it is real.

Unless they are in a hanging basket, it’s recommended to insert a trellis into their container, allowing the plants to climb and grow.

Commonly Grown Hoya “Species”

Hoya australis– has huge, waxen, deep-green waxy leaves measuring nearly four inches across, and speckled with silver. It is a vigorous, strong grower, the vining kind with distinctly fragrant flowers, pink with red crowns.

Hoya bandaensis– Sturdy plant with deep-green glossy leaves.

Hoya bella– is a handsome dwarf, small growing species with slender upright branches that droop down as they age; non-climber, small leaves are thick, dark green; flowers are white with purple centers. An old favorite.

Hoya carnosa– Old-timer with shiny dark-green oval-pointed leaves, spreading sprays of faint pink flowers centered with a red star-crown. This one climbs best by sinking its aerial roots into a porous support like a moss pole.

Hoya Plant Care: Questions and Answers

What To Do When Your Hoya Plant Is Not Blooming?

Question:I have an 8-year-old HoyaHindu rope plantvine, growing long climbing vines but never flowers. What can I do to make it produce flowers?HB, Minnesota

Answer:Many home Hoya growers cannot get their sweetheart plant to bloom. Hoya plants flourish best in bright indirect light, in humid air, with ample moisture at the roots. But Hoya plants need a break.

More on:Hoya lighting needs here.

During winter, keep the plants cool, 50° degrees Fahrenheit, and rather dry. Continued high temperature, fertilizer (liquid), and moisture promote leaf and stem growth and prevent the formation of flower buds.

After the buds are set, you can increase the temperature again slightly.

Hoya Plant In Soil Not Flowering, Long Cutting Growing in Water Does Flower – Why?

Question:I have two plants of Hoya motosekei. The original plant is growing in soil. I took a long cutting and rooted it in a glass of water. It is still growing in the water, sitting on the window sill.

The plant in the glass of water blooms. The one in the soil does not. Do you have any idea why?

Answer:The first important item to remember is that the Hoya flower only “shows up” on long shoots. Secondly, the wax plant flower will do best when placed next to the glass on the window sill as well.

Personally, I would pot up the blooming plant in well-draining soil like an African violet potting medium. Place both plants in the window, keep them well watered, and next spring, you should see more blooms.
