Flaming Katy Facts

The flowers of the flaming Katy usually come in clusters and bloom shades of pink and red, making it a great addition to any vivarium that has a lot of green plants.

Flaming Katy is actually a perennial evergreen, meaning it’ll stay green and in bloom year-round!

Its foliage can also stay vibrant for months to years as well.

Another important fact to keep in mind is the plant’s toxicity to animals.

The Kalanchoe species contains cardiac glycosides, which makes it especially dangerous to cats and dogs.


The flaming Katy’s flowers will form in clusters and create a unique mounding shape that slightly trails down below its main stem.

Its thick, fleshy leaves can come in a variety of shapes, depending on the individual plant, with some shapes ranging from stubby to round to even spade-shaped leaves.

The leaves can range in hue, as much from green and white to dark, deep purples and reds.

Its flowers will range in color, depending on the species, but will primarily bloom shades of light pink with some shades of red.


Flaming Katy comes from the tropical forests and grasslands of Madagascar and prefers high humidity levels, at least 65%, with evenly moist soil to thrive.

The temperature in its native environment will range between the high 60s and low 90s.

Flaming Katy also loves to have lots of indirect sunlight and can do great in a bright light room with a window.

pH Preference

Flaming Katy does well in soils with a pH range between 6-7.

If the pH of a terrarium is too acidic, it will affect the number of nutrients and essential elements the succulent can absorb, preventing it from growing or flowering.

It is best to check the pH range of the terrarium before introducing the flaming Katy to ensure the best growth and blooms possible.

Vivarium Type

The flaming Katy is quite an easy-going species.

With that in mind, it will not be too complicated when it comes to choosing the type of enclosure it is grown in.

It is best to try and replicate the plant’s natural habitat as much as possible.

Doing so will make it easier to provide this succulent plant with its basic needs.

The proper setup and theme of the enclosure will make a big difference to the overall look and health of the plant.

Here are recommended vivariums it will do well in:

    • Terrariums – Fully terrain-based enclosures with little to no aquatic features.

Vivarium Placement

Flaming Katy is a great fit for many terrariums and can fit a variety of themes.

Since this plant loves partial sun, it should be placed in the terrarium near the top portion if you want it to get some of that indirect light.

However, since this plant may rot when exposed to too much sunlight, make sure it’s not in an area that will cause the plant to get too much direct sun.


Flaming Katy does best in well-draining, loose terrarium soils, and acidic substrates with good air circulation.

If the soil is too compact or does not drain properly, it can cause the Flaming Katy to rot.

The best substrate for this plant would be a mix of coco fiber, sand, and peat moss, which would make for a great pH-balanced substrate that is light and well-draining.


When developing a terrarium with flaming Katy, it is important to understand exactly how much terrarium lighting it needs to stay healthy and look its best.

As long as the light it receives is indirect and dispersed, the Flaming Katy will do just fine in a terrarium.

If the light is too intense, it can cause the plant to burn and sicken.
