This plant is native to tropical East Africa, the Horn of Africa, and Yemen.

It is a plant that reaches 8 m long. The trunk has a bottle-shaped with a few twisted branches.

The main stem base is fleshy, somewhat elongated, conical or cylindrical, measuring up to 2 m high and 60 cm wide, and its bark is smooth and greenish.

The leaves are deciduous, about 1.5 to 12 cm long and 1.5 to 13 cm wide, gray to light green underneath, and have five veins from the base.

The petiole is 1 to 8 cm long, and the stipules are narrowly triangular 0.5 to 1 mm.

The color of the flowers is cream or yellowish-green. 

Male plants have 3 to 5 flowers, and females 1 to 3 flowers.

When the flowers are male, they are 30 to 56 mm long. In contrast, the female ones are between 15 to 24 mm long.

Each inflorescence produces between one to two fruits 2 to 4.5 cm long and 1.5 to 3 cm wide. 

Each fruit capsule produces between 15 to 35 seeds, which are 4.5 to 6 mm long.

Adenia venenata is a plant that I recommend to anyone.

Adenia venenata Care

Follow these steps, and you won’t have any issue with the care of your succulent plant.


These plants appreciate warm, sunny climates. 

They tolerate high temperatures quite well. 

The ideal temperature for this plant is approximately 70ºF (21ºC).

If you have your plant in a pot, it is best that you keep your Adenia venenata inside your home during the autumn and winter months, all with the purpose of protecting it from extreme cold.

If the temperature where you live is not lower than 60ºF (15ºC), you can have it outside, while if the temperature is below 44ºF (6ºC), it is best to have it inside.


If you have your plant in a pot, it is best to transplant it every two or three years. 

If you notice that the roots are coming out of the drainage hole, it is time to transplant.

Make sure that the new pot has a drainage hole; you can also take the opportunity to add some slow-release fertilizer to strengthen your plant.


You don’t have to prune Adenia venenata as regularly. 

You just have to remove those leaves that are already wilted, to give the plant a more beautiful appearance and maintain its health.


This plant’s sap is poisonous, so you should handle the plant with caution, especially when pruning or transplanting your adenia venenata. 

You should also be careful with thorns, as they can be dangerous.


Adenia venenata can grow quite well in full sun or partial shade. 

Something curious about this plant is that the Adenia venenata likes to be in the shade, while the leaves like to be in the sun.

One recommendation is to protect your plant during the sunniest summer hours to prevent the leaves from burning.


A very porous substrate is needed; you can add a universal substrate: pumice, vulcanite, and perlite to improve drainage.

If you don’t want to get too complicated with the substrate, you can buy a substrate for cacti and succulents, as they do very well.


The best way to propagate your Adenia venenata is through seeds, since propagation by cuttings is possible, but usually, the plant does not produce a caudex.

If you want the plant to produce seeds, the best way to propagate them is from cuttings since they bloom more freely. 

But if you want the plant as decoration, it is best to grow them from seeds, since they develop a caudex.


This plant should be watered with some regularity in summer, while in winter, it is best to keep the soil dry as much as possible to prevent the plant from rotting easily.

 Also, this beautiful plant does not like to be watered a lot when it has no leaves.

Pests or diseases

The main problem with adenia is root rot when overwatered.

During spring and summer, keep taking care of your plant to prevent it from getting sick from some very common pests at this time of year.


You can fertilize your plant during the active growing season, that is, during spring and summer.

You only have to apply a specific fertilizer for cacti and succulents once every 2 to 3 weeks.

During the fall and winter, suspend fertilization; at this time, the plant does not need to be fertilized.

What you can do is add some fungicide during the winter (it can even be homemade) to prevent the appearance of fungi.
