Hoya

Hoyas, also known as Wax Plants, are a genus of tropical plants native to Asia and Australasia. They are popular houseplants prized for their thick, waxy leaves, trailing or vining growth habit, and extraordinary clusters of star-shaped fragrant flowers. With hundreds of species and cultivars available, they range from compact tabletop plants to long trailing vines suited to hanging baskets and shelves.

Hoyas are forgiving and adaptable. Place them in bright indirect light for best growth and flowering, though most tolerate moderate light. Water when the top inch or two of compost has dried out, then water thoroughly and allow to drain fully. Reduce watering in winter. Use a free-draining potting mix to avoid soggy roots. Feed lightly in spring and summer with a balanced houseplant fertiliser. Hoyas prefer to be slightly root-bound and do not need repotting often.

Hoyas are generally considered non-toxic to cats and dogs, making them one of the better choices for pet-friendly homes. That said, ingesting any houseplant can cause mild stomach upset in some animals, so it is always best to keep plants out of reach of curious pets.

The most common reasons a Hoya fails to flower are insufficient light, too much warmth in winter, or the plant being too young. Hoyas flower best when given bright indirect light, a slightly cooler and drier rest period in winter, and allowed to become somewhat root-bound. Most Hoyas need to reach a certain level of maturity before they flower for the first time. Patience is key as a well-established plant can produce blooms for decades.

Yes, Hoyas generally flower better when their roots are fairly snug in their pot. This is one houseplant where you do not need to rush to repot. When you do repot, choose a pot only one size larger and use a free-draining mix specifically formulated for Hoyas. Repotting into too large a container increases the risk of overwatering and can delay flowering.

A healthy Hoya can flower once or even twice a year, typically in spring and summer when light levels are higher. The flowers emerge from persistent structures called peduncles or spurs. It is important not to remove these after flowering, as the same spur will produce new flower clusters in subsequent seasons. Fragrance is often strongest in the evening, so positioning your Hoya where you spend time at night makes the most of its scent.
