Is a Snake Plant a Cactus? What You Need to Know

{“statusCode”:401,”message”:”License key missing”}

Snake Plants are not cacti; they are succulents from Asparagaceae, and Cacti come from the genus Cactaceae. The main difference is that Snake Plants have proper leaves, while cacti have areoles.

If you want to grow a snake plant, you might be confused about taking the plant for a cactus. In this post, we will look at both plant types and identify their similarities and differences. Read on and find out why a snake plant is not a cactus.

Why are Snake Plants not Classified as Cactus?

Snake and cacti are succulent plants, with over 60 plant families in this group. Succulents have an adaptation feature: they store water in their leaves, roots, and stems. This adaptation is the reason behind the name succulents. Typically, succulents are drought-resistant, and the water stored in the plant tissues is used during the dry periods.

You will also find that some plants classified as succulents are aquatic, and their water reserves serve a different purpose for such plants.

Plants with these features are collectively known as xerophytes, and cactus and snake plants lie in this group, among others. Xerophytes can withstand long periods of drought due to their adaptations. Also, their adaptations go beyond the water storage features to having deep spreading roots, which help reach water and take up water from rare random rains.

It is worth mentioning that both snake plants and cacti are xerophytes. However, not all succulents are xerophytes, and cacti are a sub-category (family) within the succulent group of plants.

Differences Between Cactus and Snake Plants

Cactus are slightly different from other succulent plants, including snake plants. As we are about to discover in this section, certain features distinguish snake plants from cacti:

What are Areoles?

Areoles are distinct features that only exist in cacti, distinguishing a cactus from other succulents such as snake plants. For this reason, you cannot classify a plant as cactus unless it has areoles.

Areoles are small, rounded cushion-like structures found on the plant’s surface. New growth, such as branches, flowers, spines, hair, and leaves, develops on the areoles.

Due to the purpose, they serve in the plant. Scientists believe that areoles are condensed lateral shoots.

Difference between cactus and snake plants’ leaves

Cactus leaves are very different from those of snake plants. In the cactus, leaves appear as spines that grow on the areoles. These leaves are reduced in size to reduce water loss by the plant. Also, they work as a protective adaptation against animals that wish to feed on the plant.

On the other hand, Snake plants have actual leaves growing directly from the stem. In snake plants, the leaves are big and fleshy as they are the water storage features of this succulent plant.

While snake plants process food on their leaves, the cactus does so on its stem. Snake plants have chlorophyll on their thick foliage, and these thick leaves in snake plants grow in spiral rosettes.

Where do their stems grow?

The stems of these two plants are entirely different. Snake plants have branches growing under the ground as rhizomes, from where their leaves also develop. These rhizomes serve the purpose of vegetative propagation because new plants produce on them. Additionally, they are used for food storage, dry periods, and feeding new plants.

As this advanced stem runs along the ground, it develops widely spread roots that help the plant obtain as many nutrients and water as possible. Since the plant roots are shallow, the rhizome provides additional support.

Cactus stems are thick green and fleshy structures, and the stem makes the most significant part of the plant we see. In the cactus, the stem stores water for the plant and uses its chlorophyll to process food through photosynthesis.

Stomata location

Even though the stomata of cactus and snake plants function similarly, they are located in different parts of these plants. You will find the stomata on the plant’s stem in the cactus, while snake plants have them on their leaves.

Remember, cacti do not have actual leaves, and their leaves are more protective features; thus, they don’t serve the same purpose as snake plants.

Similarities of Snake Plants and Cactus

Certain features are also standard in cactus and snake plants, making these plants more confusing. However, having identified the differences between the two, it should be pretty easy to identify one from the other.

Natural habitat

Snake plants and cacti naturally grow in dry areas that hardly receive rainfall. As a result, their adaptive features are meant for survival in these harsh climatic conditions enabling them to store as much water and food as possible.

Since they grow in the same environment, they have similar growing conditions. Both plants are less hardy and require well-drained soils, indirect bright light, and less frequent watering.

Water storage

Cactus and snake plants store water in their tissues for use during drought. As a result, these plants can survive for long periods without rainfall or watering.

If you have these plants at your home, you will realize they don’t need frequent watering since excess water kills the plant by causing root rot.

CAM Photosynthesis

Snake plants and cacti, among other succulents, utilize a different process of photosynthesis known as Crassulacean Acid Metabolism (CAM). Due to their growing environment, they adapt to their stomata opening at night.

Naturally, stomata are designed to exchange gases and release excess water by plants through diffusion and transpiration, respectively. As the plants avoid losing water when scorching during the day, their stomata open up at night when they take the CO2 necessary for photosynthesis. At the same time, the plant releases pure oxygen into the environment.

The plants then use the stored CO2 during the day in light to manufacture energy. For this reason, both plants are known and loved for their air purification properties.

FAQs on Is a Snake Plant a Cactus? What You Need to Know

How long can snake plants go without water?

While some plants are fairly high-maintenance and borderline dramatic, sansevierias, also known as snake plants or mother-in-law’s tongues, are quite the opposite. These trusty greens are so resilient they can go up to two weeks without water.

Do snake plants make good bedroom plants?

Similar to other household succulents, snake plants help to filter indoor air. What’s unique about this particular plant is that it’s one of the few plants that can convert carbon dioxide (CO2) into oxygen at night. This quality makes it an ideal plant for bedroom decor since it can help regulate healthy airflow.

How Long Does It Take for A Snake Plant to Bloom?

First, you will see a stalk with a bit of fluid has come on the plant, and after 2-4 days, it develops a flower. Sansevierias flower stalk is long, white, or creamy, like lilies. These stalks can grow about 2-3 feet and build flowering buds.

Is snake plant poisonous?

Because they do just fine in low light, snake plants are common in office spaces and homes. But they are also poisonous if ingested in large doses, can cause nausea and vomiting, and the poison found in the plant has a numbing effect that can cause the tongue and throat to swell.

What Do Sansevierias Flowers Look Like?

The snake plant produces flowers on a long flower stalk, and the branch may reach up to 3 feet. The flowers are usually white or cream. As the flowers begin to open up, they will start resembling lilies. And these would even have a powerful and pleasing fragrance that may occasionally attract pests.

Conclusion on Is A Snake Plant A Cactus.

Snake plants can be easily confused for cacti as both plants have water storage tissues. They also naturally grow in the same environmental conditions and utilize the exact photosynthesis mechanism.

However, as we saw above, cactus plants have one distinct feature, the presence of areoles. This unique feature sets cactus apart from other succulents, including snake plants. Some other features and characteristics will help you distinguish the two, such as the shape and size of leaves and stem type.
