What is a Kalanchoe Plant?
Kalanchoe are actually a whole family of plants in the succulent genus. These are very pretty plants and, as with many succulents, they look as striking as they are peculiar. This, together with the natural resistance of most plants of its genus, makes kalanchoe plants highly appreciated by fans of gardening and decoration.

Kalanchoe blossfeldiana, the most popular
It is the most popular kalanchoe and also the most common in garden establishments. It stands out for its flowers of varied but very vivid colors, and for its large, fleshy, intense green leaves. To blossom it needs to be in a location where it receives plenty of natural light, and if conditions are not optimal it may not bloom every year.
There is a specific variety of this kalanchoe called calandiva. It looks a lot like the original blossfeldiana, but its flowers are double, so its flowering is even more showy.
This peculiar plant with leaves arranged in a star shape is known for its very slow growth, although it can reach heights of up to 1 meter. Its leaves are covered with small whitish hairs, which give the plant a soft and velvety touch. The tips of its leaves have brown spots, serrated like their margins. There are many kalanchoe tomentosa varieties, such as:
- Kalanchoe tomentosa
- Kalanchoe tomentosa cv. chocolate soldier
- Kalanchoe tomentosa variegata.
Kalanchoe ‘Tessa', a hanging flowering plant
This type of kalanchoe received the Royal Horticultural Society's Award of Garden Merit at the time. It is a hanging kalanchoe , which reaches heights of up to 30 centimeters. Its leaves are slightly serrated and fleshy, and its striking pink to red flowers, tubular or bell-shaped, sprout from very small stems. It is both an indoor and outdoor plant.
Kalanchoe ‘Pink Butterflies'
This succulent plant is named after its young shoots, which are born at the edges of its leaves and are a pretty pink color, which makes them look like flowers. Unfortunately, the life span of these youngsters is quite short.
This is another of the most popular kalanchoe types among succulent plant fans. Its leaves, with a serrated edge and with dark spots on the underside, are born on erect stems of good thickness. It is rare for it to flower, but a large number of suckers grow from the jagged edges of its leaves.
This kalanchoe can be grown both in soil and in a pot, although like many other species, it needs a great deal of natural light to flourish. Its leaves are large and rounded, light green in the center and pink at the end, very beautiful and decorative.
A kalanchoe native to the island of Madagascar, which grows to heights of one meter, it is one of the fastest growing types of kalanchoe. Its leaves are fleshy and toothed, with edges marked by a darkened line. It is a succulent that can be kept indoors but, like most, it cannot stand the cold.
Also native to Madagascar, this kalanchoe is characterized by being one of the largest of its kind, and it is one that is shrubby. It can reach heights of up to 3 meters, looking like a small tree with large fleshy leaves.
It is evergreen, so it is commonly used to decorate gardens or spaces that should not be dirty.
Another species with the same origin as the previous two. Its name comes from the botanist Gaston Bonnier, after whom it was called. Its leaves are opposite and up to 6 centimeters in length, very beautiful and with a silver stem. They are light green in color dotted with dark patterned spots, and their flowers are red with a yellow corolla, very decorative.
We end with the largest type of kalanchoe, as it can reach heights of up to 8 meters. This plant, also native to Madagascar, forms trees of small or medium size, with a stem that widens at its base to 10 centimeters in diameter and that forks as it grows. Its inflorescences, in bright pink and purple tones, are the most showy and striking.
Now that you know different types of kalanchoe and if you are thinking of having one in your home, we recommend choosing properly which one you can take better care of at home.
Is kalanchoe poisonous to humans?
The Kalanchoe most often cultivated indoors is likely to be the Flaming Katy (Kalanchoe blossfeldiana). With the brightly colored flowers and the attractive leaves, it is a room decoration that is as grateful as it is easy to care for and that also thrives on the terrace.
The Flaming Katy is considered non-toxic, despite the fact that the constituents of the ornamental plant are largely unexplored. However, it has also been reported that a baby suffered from vomiting and abdominal pain after consuming parts of plants above ground.
Other Kalanchoe species such as Kalanchoe Beharensis, on the other hand, are considered poisonous because they contain, for example, cardiac glycosides, leading to symptoms like vomiting, diarrhea, and cardiovascular problems.
Under no circumstances should these plants be placed within the reach of children.
As with all indoor plants, the following applies: Even if a plant is considered non-toxic, it should be positioned so that babies and toddlers do not get to the plants. For adults, rather harmless active ingredients can trigger much stronger symptoms in children.
Is kalanchoe toxic to cats?
Even if many kalanchoe species are non-toxic to us humans, even babies, this unfortunately does not apply to velvet paws. The felines react very sensitively to the acids contained in the leaves. If the animal eats the plant, it can have difficult breathing, convulsions, and paralysis.
For this reason, it is better to avoid kalanchoes in cat households or at least to set them up so that their four-legged roommates cannot nibble on them.
Is kalanchoe poisonous to dogs?
Dogs are reported to be particularly sensitive to the cardiotoxic effects of Kalanchoe. According to Science Direct, a review of cases from the ASPCA Animal Poison Control Center indicated that the most common signs in dogs ingesting Kalanchoe spp. were vomiting (57%), depression and/or lethargy (42%), and diarrhea (29%). Other signs included weakness, dyspnea, anorexia, tachycardia, and vocalization. No deaths were reported in dogs following Kalanchoe ingestion.
Do kalanchoe rebloom?
If you pay attention to a few points in kalanchoe care, it will bloom persistently and is a nice splash of color on the windowsill when hardly any other houseplant has flowers.
The Kalanchoe only opens its beautiful flowers when it receives less than nine hours of light. In our latitudes this period falls in the winter months, because only then are the days short enough.
