How to Grow Wax Plants and Get Them to Bloom: Hoya Plant Maintenance

Hoya Plant

Very likely a Hoya plant was the vine you saw snaking across your grandmother's kitchen. This tropical indoor plant, also known as a "Porcelain flower," is a classic because it lives forever, grows to be large, and produces stunning, fragrant flower clusters that resemble porcelain and are frequently referred to as "Wax plants" because of their thick waxy leaves. The subject of this essay is hoyas, specifically how to cultivate them as indoor plants and induce blooming.


Although many claim that caring for Hoya plants is among the easiest of all indoor plant maintenance, we have cared for numerous Hoyas at the nursery over the years and have discovered that each has unique preferences. Here are the needs for five of our favorite hoya cultivars. You may learn the ins and outs of hoya plant care by following along as we go from most common to least common. We'll also give you a trick to encourage blossoms!


Our 5 favorite "standard" Hoyas

These Hoyas are forgiving, relatively fast-growing, and some are reliable bloomers given proper care. Luckily, the following plants are some of the easiest Hoyas to find!


1. Hoya carnosa (top left)


Why it’s special

This is the classic wax plant our grandparents grew. Dark green, large, almond-shaped leaves grow on long vines, which will eventually put out creamy flower clusters.


What it likes

Medium to bright indirect light. Less is more when it comes to watering; we like to wait until the leaves pucker slightly.


What it dislikes

Direct sun, artificial light, dark corners.


2. "Krimson Queen" Hoya carnosa (top center)


Why it's unique

Everything you love about the traditional carnosa, but with white and pink-lined leaves. This Hoya, sometimes known as "Tricolor," occasionally has leaves that are entirely white and stems that are brilliant pink. A knockout!


What it enjoys

It thrives best in extremely bright yet indirect light. appreciates the heat and humidity as well. Observe the aforementioned watering instructions for typical carnosa.


What it detests

low-medium light, drafty windows, and a chill. especially vulnerable to overwatering. Portlanders, make sure you have a place that is bright enough to satisfy this one!


3. "Krimson Princess" Hoya carnosa (bottom right)


Why it's unique

This Hoya carnosa cultivar boasts vibrant green, cream, yellow, and pink variegation on its leaf. The central variegation resembles brushstrokes in watercolor painting.


What it enjoys

Like to its variegated relative "Krimson Queen," this Hoya requires a sunny area away from the sun. Like a carnosa, water.


Why it doesn't like

low-medium light, drafty windows, and a chill. especially vulnerable to overwatering.


4. obovata hoya (top right)


Why it's unique

Wonderful spherical, dark green leaves with a subtle speckling cover this hoya. This Hoya grows relatively quickly and sets blossom earlier than other Hoyas do. And the blossoms have a chocolatey scent!


What it enjoys

One of the more resilient Hoyas we've come across is this one. While it tolerates medium light, it still prefers strong light.


Why it doesn't like

those large leaves hold a lot of water from overwatering. Avoid watering till it puckers. And gloomy, drafty nooks and intense sunlight.


5. Austral Hoya (bottom left)


Why it's unique

Those foliage! This Hoya has a spade-like form and is velvety to the touch. It also sends out vines that grow more uprightly than carnosas.

What it enjoys


It is harder to discern when these plants need watering because this Hoya has thinner leaves than other Hoyas. Before you notice significant puckering or wilting, let the soil dry up and then water it.


Why it doesn't like

Direct sunlight, overwatering, and dark corners.


Exceptional mentions

Hoya kerrii, Hoya pubicalyx, Hoya lacunosa, and Hoya bella.


Information on Hoya carnosa

In the past, Hoya carnosa was the Hoya that was most often grown in the West. The plant has been grown for genetic changes of the leaves and blossoms by hybridization with other species, giving us new plants with new names. Hoya carnosa 'Krimson Queen' and 'Krimson Princess,' two variegated varieties of the plant, have already been noted; nonetheless, here are some more cute changes to the standard wax plant:


Chelsea Hoya carnosa

— larger, broader, somewhat cupped leaves, and a beautifully cascading growth pattern under the weight of its hefty foliage


Carnosa Hoya 'Krinkle 8'

Its leaves have 8 adorable hollowed-out sections that give them the appearance of empty pea pods and are gently cupped.

the plant has unusually rope-like leaves that are wrapped in on themselves and never completely open.


Jade Hoya carnosa —

Hoya 'Mathilde,' a cross between H. carnosa and H. serpens, with coin-sized, splashy leaves that are a brighter green than the ordinary H. carnosa.


"Chouke" Hoya—
