Kalanchoe humilis is an attractive succulent shrub with pale green leaves, usually strongly marked with purple or maroon spots. It grows up to 3 feet (90 cm) tall. Stems are simple or with few branches, woody at the base, purple or slightly glaucous, and up to 8 inches (20 cm) long. Leaves are egg-shaped, up to 5.2 inches (13 cm) long, up to 2.4 inches (6 cm) wide. They are with a slight glaucous bloom on both sides and have margins with rounded teeth. Flowers are small, purple to green, and appear in mid-summer on erect, branched, and up to 12 inches (40 cm) tall inflorescence.


USDA hardiness zone 8a to 10b: from 10 °F (−12.2 °C) to 40 °F (+4.4 °C).

How to Grow and Care

Kalanchoes are not particularly hard to grow, and the flowering varieties are highly rewarding for their colorful and long-lasting flowers. They prefer bright, sunny locations, especially in the summer growing season. During the winter, consider a south-facing window.

Water moderately throughout the summer and reduce watering in the winter. Let the soil surface dry out between waterings, and in the winter, the plant can almost dry out. Watch the fleshy leaves for signs of water distress. They prefer warmth. Do not let fall below 55ºF (12.7ºC).

Many people discard the plants after the bloom is over, but this isn't necessary. Simply cut off the flowering head, let the plant rest with reduced water, and resume its regular care. It should flower naturally in spring. Professional growers force Kalanchoes to bloom throughout the year (they are a short-day plant). The two pendant Kalanchoes make excellent hanging plants.

How to Grow and Care for Kalanchoe humilis?

Kalanchoe humilis is super easy to grow and maintain. It can tolerate a period of neglect.

Keep reading to learn how to care for Kalanchoe humilis.

Light requirements

Light is one of the most critical needs of Kalanchoes humilis. It thrives best in bright sunny places. The outdoor succulents can be grown under full sun to partial shade. When the summer is extremely hot, and the sun is too intense it is advised to grow your Kalanchoe succulents in partial shade.

The indoor Kalanchoe succulents should be placed beside bright sunny windows for ample of sunlight exposure. Avoid direct contact of your succulents with the windows in summer, when the temperature is too hot it may cause the sunscald or burning of leaves.

If your succulents start growing abnormally tall and appear leggy or stretched out, it indicates that your succulents are not getting enough sunlight. Try to move your succulents near a bright sunny window.

Potting soil

Kalanchoe humilis should be grown in a well-draining soil mix. You can use a standard succulent soil mix readily available in the market or you can prepare a potting medium on your own by mixing 40 to 50% sand or grit with peat moss.
Avoid using a potting medium that is too clayey. It lacks the porosity to let the excess water drain ultimately the water will accumulate in the soil causing root decay.

Temperature and humidity

Kalanchoe humilis thrives best at warm temperatures and cannot tolerate below-freezing temperatures. The minimum temperature it can tolerate is 10° F. If the temperature drops below 10° F, it will cause freezing injury. A few hours of exposure to below freezing temperatures is enough to cause the death of succulents. Bring the potted Kalanchoes indoors when the temperature drops below freezing.

They don’t require specific humidity and can generally take all levels of humidity.
USDA hardiness zones

Kalanchoe humilis is grown as a hardy succulent in USDA hardiness zones 8a (10 ° F) to 10b (40 ° F).


Kalanchoe humilis is a drought-smart plant that can tolerate a period of neglect. They need to be watered more often during the summer season, while less often during winter. Water your succulents well and let the excess water drain. Always wait between watering to let the soil dry out completely.

Insert your finger in the soil if the top 1 to 2 inches feel dry, it is time to water your succulents.

Overwatering is the worst enemy of Kalanchoe succulents. It causes rotting and disintegrations of the roots and also increases the chances of fungal growth.


Kalanchoe humilis can be propagated easily by offsets, leaf, and stem cuttings. It can also be propagated using seeds. But seed propagation is slightly different and requires a bit of expertise.

To take the cuttings use a clean scissor or gardening shears. Cut the desired part carefully. Kalanchoe humilis produces small rosette offsets. To propagate from offsets cut the offsets from the main stem with a sharp scissor. Let the cuttings and offsets sit at a warm dry place for 2 to 3 days to develop callous.

Place the cuttings on the top of the pre-moistened potting soil. Keep misting the cuttings 5 to 6 times a day regularly to keep the soil evenly moist.

Put the pots near a bright sunny window. Don’t expose your succulents to direct bright sunlight until they establish in the soil. Kalanchoe humilis will start rooting after 2 to 3 weeks and will be ready for transplantation into new containers.


Kalanchoe humilis does not require repotting very often. It can survive in the same container for years. However, a general rule is to repot all Kalanchoe succulents every 2 years, it will provide fertile potting soil to the succulents with a nutrient boost.


Kalanchoe humilis doesn’t require fertilization. It gets plenty of nutrients from the potting medium. However, fertilization will provide an extra dose of nutrients to your succulents. You can use a balanced fertilizer to fertilize your succulents biweekly or monthly.


Kalanchoe humilis doesn’t require pruning and grooming. However, you can remove the spent blooms and dead leaves to encourage better growth next season.


Kalanchoe humilis is quite tolerant to insect pests. You can occasionally find Mealybugs and aphids attacking the indoor succulents. You can use 70% alcohol or neem oil to get rid of these creepy bugs. In case of severe infestation, you can use a non-toxic insecticide spray.

Another problem of Kalanchoe humilis is overwatering. Water your plants moderately and avoid overwatering.

Kalanchoe humilis is a desirable ornamental succulent at bright sunny locations. It looks beautiful in succulent gardens and landscaping and at frost-free locations.

Care and Propagation Information

General Care for Kalanchoe humilis

Kalanchoe humilis is a beautiful, variegated succulent that is excellent for beginners. It grows well in rock gardens, as well as container gardens. Its flowers attract hummingbirds to your outdoor garden.


Kalanchoe humilis has typical watering needs for a succulent. It’s best to use the “soak and dry” method, and allow the soil to dry out completely between waterings.

Where to Plant

Kalanchoe humilis is not cold hardy, so if you live in a zone that gets colder than 10° F (-12.2° C), it’s best to plant this succulent in a container that can be brought indoors. It does well in full to partial sun.

Plant in an area of your garden that gets 6 hours of sunlight a day. If planting indoors, place in a room that gets a lot of sunlight, such as near a southern-facing window (if you’re in the Northern Hemisphere).

How to Propagate Kalanchoe humilis

Kalanchoe humilis is an easy succulent to propagate from stem cuttings and offsets.


To propagate Kalanchoe humilis from cuttings, use a sharp, sterile knife or pair of scissors and cut a piece of the plant just above a leaf on the stem. Allow it to dry for a couple of days, and place in well-draining soil.


Kalanchoe humilis will produce small rosette offsets. Cut the offsets off from the main stem with a sharp, sterile knife or scissors. Allow the offsets to dry for one to two days before laying on well-draining soil.

Kalanchoe humilis

Kalanchoe humilis is a small perennial and succulent shrub belonging to the Crassulaceae family and native to the south-east of the African continent.

It grows primarily on rocky substrates near freshwater sources but never on flooded substrates.

It is a plant grown throughout the world as a collection plant due to the beauty of the foliage and its simple cultivation requirements.

Typical leaves of the tabby Kalanchoe, Kalanchoe humilis

This species usually develops a small central stem of +/- 8 cm in height, slightly branched and slightly lignified at the base.

In greenhouse conditions with quality substrates, this stem can exceed 15 cm in height.

The stems generally have more than 0.5 cm thick and a reddish-green color.

The leaves are arranged opposite on the stems and tend to remain fairly compact (one pair over the next).

Each leaf is +/- 10 cm long and +/- 4 cm wide, they are lanceolate or elliptical in shape with the margin created in the mid-terminal region.

All the leaves are clearly fleshy and exhibit a greenish-gray color with numerous reddish-brown spots of great ornamental value.

In all the leaves it is possible to observe a pale green central line. The spots are generally arranged forming horizontal bands. Margins also tend to stain.

In this species, the basal leaves will eventually fall, leaving the base of the stems completely bare.

The flowers are grouped numerous into highly branched terminal inflorescences that develop floral stems over 20 cm high.

All flowers are small with pinkish-green petals.

In this species, the flowers are not decorative and that is why many growers cut the inflorescences.

Tips to take care of the Kalanchoe humilis

Kalanchoe humilis is a very easy plant to maintain in the garden. Next, its basic cultivation requirements:


It is essential to provide a lot of lighting to avoid the etiolation of the stems.

The leaf spots are accentuated even more under conditions of intense lighting.

It is recommended to expose to the sun in the early hours of the morning and late in the afternoon.


It grows much better under the influence of high temperatures.

The optimum temperature range for the species is between 20ºC-29ºC. It does not tolerate temperatures below 0ºC for long periods.

It requires a substrate slightly rich in organic matter and with optimal drainage.

Prolonged waterlogging will quickly rot the radical system. Commercial substrates for crass and cacti can be used without problems with an extra aggregate of coarse sand.

Remember the previous disinfection of the substrate to avoid the proliferation of pathogens that are in it.

Irrigate preferably after drying the surface of the substrate during hot seasons.

Watering should preferably be done at the height of the substrate to avoid wetting the foliage

Plagues and diseases

Attacked mainly by mealybugs and mollusks.

The mealybugs cause the fall of the leaves, wilting of the flowers and allow the proliferation of pathogenic fungi.

Molluscs devour sections of leaves and stems in a short time.


It is multiplied by cuttings of stems or from leaves.

To propagate Kalanchoe humilis from cuttings, use a sharp, sterile knife or pair of scissors and cut a piece of the plant just above a leaf on the stem. Allow it to dry for a couple of days, and place in well-draining soil.

Kalanchoe humilis will produce small rosette offsets. Cut the offsets off from the main stem with a sharp, sterile knife or scissors. Allow the offsets to dry for one to two days before laying on well-draining soil.
