Cotyledon is one of the most attractive genera of succulent varieties that belong to the Crassulaceae family.
These succulent plants can be found mainly across Southern Africa, but you can also find them in the arid and other drier regions, even in the northern Arabian Peninsula.
In South Africa, you may get only ten species, and unlike Tylecodon, Cotyledon grows well even in summer and winter climates.
The leaves of these plants are evergreen and decussate, and they come in different shapes. Most of the Cotyledon species have similar thick leaf patterns.
The leaves are arranged at a 90-degree angle to their former and following pairs. The flower colors often vary from orange to yellow.
The flowers of Cotyledon varieties are tubular and pendulous, appearing at the top of the stout stem.
Remember that all parts of most plants are poisonous and extremely dangerous.
Nevertheless, many people worldwide have been using some of the species as traditional medicine.
These particular species are used for removing corns on feet, or they’re collected as lucky charms.

Popular Cotyledon Varieties
Cotyledons are a popular houseplant because of their low maintenance needs and attractive foliage.
There are many varieties of Cotyledon, but these are some of the most popular.

Cotyledon campanulata is a dwarf-sized succulent plant. It has finger-like leaves with red tips. Each leaf grows up to 12 inches wide and 8 inches tall.
During the late spring, these plants produce small flowers with yellow petals. Like most species of Cotyledon, this variety is native to Southern Africa.
Cotyledon campanulata needs full sun to grow indoors. Partial sun is a better option if you live in a cold region, but if these plants are grown under warm temperatures, you should provide them with a bit of shade.
Water them deeply but less frequently. Make a watering schedule depending on the temperature of your area.
Make sure that the pot has at least one drainage hole. A well-draining growing medium is necessary for growing Cotyledon campanulata.
Cotyledon Ladismithiensis
Cotyledon ladismithiensis is another species belonging to the Crassulaceae family. The leaves have a unique elliptical shape and look like the paws of a bear.
Hence, it is alternatively known as the “Bear’s Paw” plant. During the winter months, this variety remains dormant.
Generally, it grows up to 40 inches, or more than 3 feet tall. It can be a catchy addition to your indoor garden.
This slow-growing succulent needs a lot of sunlight to grow. Let the top few inches of your potting soil dry before watering.
Never overwater as it will kill this succulent. Make sure that these plants are grown in well-draining soil.
Avoid using clay or heavy soils for preparing this mix. Use coarse and inorganic materials to improve the drainage condition.
Cotyledon Mint Truffles
Cotyledon mint truffle succulents come up with flat but fleshy leaves. This low-growing plant grows very slowly, and over time, the leaves form a dense pack.
The leaves of this variety are green and fleshy, but they have red edges that quickly help gardeners tell them apart.
The crimson blooms that appear during the spring season between the leaves increase the beauty of this plant.
This species of the Cotyledon genus prefers a lot of sunlight to grow. Water these plants carefully because overwatering them will cause root rot.

Prepare a well-drained potting mix for growing these Cinderella succulents.
Cotyledon Orbiculata var. Dinteri
Cotyledon orbiculata var. dinteri has one of the most beautiful appearances. It has easily distinguishable white- or gray-green, fleshy, and thick leaves.
If the leaves become large and the plant is grown under direct light, you will notice the dark red edges.
During the flowering season, this plant produces orange color bell-shaped blooms.
This dinteri variety needs a sunny location, like near the south-facing window.

Cotyledon Plants Care Tips
Cotyledon plants are considered succulents. Hence, their requirements nearly match the demands of other succulents.
In this section, we will help you learn about their basic needs so that you can grow them in your indoor garden.
Light
Succulents belonging to the genus Cotyledon need a lot of sunlight to grow. We suggest you keep them near the south-facing window.
Indirect light is considered the best for growing them because the direct sun can burn those fleshy leaves during the summer months.
During the winter season, you don’t have to worry about light intensity, but during the summer months, make sure that there is filtered sunlight, not direct sun.
Temperature and Humidity
Dozen species of Cotyledon are native to Southern Africa, which is a warm region with low humidity.
Therefore, you have to ensure that the growing environment should be warm.
Try to maintain the temperature between 65 and 80 degrees Fahrenheit as this is the range for optimum growth.
The humidity is not a problem for them. These plants are hardy and can withstand any humidity levels.
Water and Fertilizer
These succulents store water in their fleshy leaves, and this is why they are drought resistant and can withstand dry conditions.
These dry-tolerant plants don’t need too much water to grow.
You have to be careful about overwatering as it can kill them by causing inundation.
Waterlogged conditions for a prolonged period will create many problems, including fungal infection and root rot. Always check the top few inches before watering.
If grown indoors, you should feed these plants once every month with organic fertilizer.
Liquid fertilizer supplies nutrients quickly as it contains the available forms of nutrients.
You can also apply balanced cacti fertilizer, but organic fertilizer is the best option for fertilizing plants.
Soil
Cotyledon plants need a well-draining soil mix. To prepare such soil mix, you need to use cacti potting mix in which there are coarse materials and other materials that retain water for a prolonged period.
Moreover, make sure that there are multiple drainage holes.
You can use coarse inorganic materials, peat moss, coco peat, and vermicompost if you don’t get a cactus mix. Avoid using clay soil for growing these plants.
Propagation and Repotting
You can propagate a Cotyledon plant by sowing seeds or stem cuttings. You can also propagate them by separating the offsets from the mother plant.
If a grower wants to propagate the Cotyledon by offset separation, they should do it during the spring. Most species grow roots and foliage quite faster.
Therefore, you may have to think about transferring the plant to a new pot.
FAQ
Why do Cotyledon Succulent leaves fall off?
Cotyledon plant leaves fall off for various reasons, including overwatering, fungal infections, plant diseases, negligent handling of the plant, and lastly, the inefficient or lack of sunlight.

As for propagating from seeds, spread the seeds in a growing medium about half an inch deep. Plant them together so that they form a mat. Germination is approximately three weeks
Where should I place my Cotyledon?
Cotyledon succulent plants should be placed near the south-facing window to get sufficient sunlight so that they get at four to six hours of indirect light per day. Cotyledons thrive in light conditions ranging from partial to full sun, depending on the species. When they are grown inside, bright, indirect light is ideal for their growth.
Conclusion
Cotyledon is a genus that contains mainly succulent plants. Each of these succulents produces beautiful blooms during the spring and summer.
