For the last few years, around Valentine’s Day, I have started seeing these adorable little heart shaped plants show up in stores. Typically they are just one small terra cotta pot with soil and about a 3″ tall “green heart” leaf. After doing some research, I found out these little cuties are called, Hoya ‘kerrii’ and I knew immediately I needed to find myself one!

About a year and a half ago, my family purchased a small Hoya ‘kerrii’ as a birthday gift to myself. I was so smitten and couldn’t wait for it to start growing me some new little hearts.

My plant sat dormant for a solid six months, growing maybe one or two small leaves. I was so worried and concerned about him. And then suddenly, it was grow time and my Hoya hasn’t stopped since!

WHAT ARE THE BEST GROWING CONDITIONS FOR Hoya ‘kerrii’?

Once Hoya’s settle in a bit, they really are very easy plants to care for. They like having bright sun, but can tolerate bright indirect light too.

They have thick, juicy almost succulent like leaves which hold water. These plants don’t like a weekly watering, typically. Maybe just a drink every two to three weeks is ideal for them. When you notice that the soil is completely dry and the leaves start to wrinkle a bit, then you know it’s time to water your Hoya ‘kerrii’.

HOW OFTEN SHOULD I WATER Hoya ‘kerrii’ PLANTS?

Since the Hoya ‘kerrii’ plants have succulent type leaves, they are good at storing water longer than your average indoor houseplant. I have found watering them on a bi-weekly schedule seems to work well.

I always think it’s smart to pick a watering day and check in on your plants each week on that day.  Your plants may not even need a drink that day, but it’s a good habit to get into.

Each Friday I stick my finger into the soil about a knuckle deep.  If the soil feels hard and dry, then you can go ahead and water your plant.  If the soil feels damp or wet, it’s best to wait another week to water.

Once it is time to water your hoya, I have been taking my plant to the sink and really soaking the soil. Even trying the method of sitting your plant in a tupperware filled with water to fully let the soil become saturated is a good ideal

WHAT KIND OF LIGHT DO Hoya Plants NEED?

I keep my Hoya in a bright window with 6+ hours of daily sun during the summer time. Although they can get by with less light, they just aren’t as happy.

Now that summer is starting to fade into fall, my Hoya still is in the same window, but he doesn’t get near the amount of direct sunlight. They will still thriving with indirect light, but it may slow down their growth a little bit.

Will my single Sweetheart plant ever grow into something bigger?

Sadly, if you get a single Sweetheart plant, it is very uncommon that they will ever grow bigger than that single leaf. The leaf will stay green and the plant will grow roots, but without a stem node, it will just stay as it is.

WHY isn’t my Hoya ‘kerrii’ plant growing?

When I first got my hoya ‘kerrii’ I could not wait to start seeing new little green hearts popping up all over the place. However, it seemed to just sit there for months without really doing much of all. A few little tiny leaves grew here and there, but it was nothing to write home about.

I have read that you need to give your hoya time to settle and acclimate to it’s new surroundings. Once mine had done that, I was sure to give it plenty of sunshine and once on a bi-weekly watering schedule, I really started seeing my plant take off.

Shortly after his initial big burst of growth, I got a U shaped bamboo stake and started wrapping all of this long limbs around that for extra support.

However, hoyas just seem to have somewhat uneven growth and as long as your plant is remaining healthy without any major red flags, if he slows down his growth… just give it time and soon you should start seeing new leaves and stems growing!

What are other names for Hoya ‘kerrii’?

The Hoya ‘kerrii’ can sometimes go for a few different names. Some people call them the Sweetheart Plant. It’s also called Hoya Heart, Wax Heart, or a even the Lucky Heart plant.

How do I get my Hoya to bloom?

Hoya plants need to be fully mature to grow flowers. This means you may need to wait for your plant to be about 5 to 7 years old before you see it’s first bloom.

Other reasons your hoya may not bloom are having your plant in a pot that is too big, too much water or too much fertilizer. Surprisingly, it is not bad for your plant to be pot-bound; it may actually encourage flowering.

Where can I get a Hoya ‘kerrii’ Sweetheart plant?

I’m thrilled to say, although you may need to do some hunting for local shops to carry Hoya ‘kerrii’ year round, it is not too difficult to find them online. Etsy, Amazon and The Sill all have multiple options for single heart leaves, as well as more mature plants.

Personally, I like the mature plants more because I like to see my plants grow and change. But both are lovely and great investments!
