Jade plants are a popular indoor plant known for their thick, fleshy leaves and ease of care. These plants are native to South Africa and are a favorite among indoor gardeners due to their attractive appearance and low maintenance requirements. However, some people may be unsure of the classification of jade plants and whether they are considered a cactus. In this article, we’ll explore the characteristics of jade plants and compare them to the traits of cacti to help determine their classification. We’ll also provide information on the care requirements for jade plants, including light, water, and soil requirements.
Is a Jade Plant a Cactus?
Jade plants, also known as Crassula succulents, are admired for their fleshy, oval leaves and thick, woody stems that resemble tiny tree trunks. These popular houseplants have a unique appearance that sometimes leads people to wonder if they are actually cacti. However, the jade plant is not a cactus, and in fact, there are a few key differences that distinguish the two types of plants.
One of the main characteristics that sets jade plants apart from cacti is their lack of areoles. Areoles are small, raised bumps found on cacti, which bear spines or flowers. Jade plants do not possess these areoles, making them distinct from cacti. However, it’s worth noting that both jade plants and cacti belong to the broader category of succulents, as they both store water in their leaves for survival in arid environments (Necps).
When it comes to care, jade plants and cacti have some similarities but also some differences. Both types of plants prefer well-draining soils and bright, indirect sunlight. However, their watering needs can vary quite a bit. Unlike cacti, which can survive long periods without water, jade plants need to be watered regularly, and their soil should remain lightly moist at all times (rePotme).
In conclusion, jade plants may share some characteristics with cacti, but they are not considered part of the cactus family. Their unique features, such as the absence of areoles, and their different watering requirements set them apart. Understanding these differences can be helpful in providing optimal care for jade plants and ensuring they thrive as attractive and low-maintenance houseplants.
Jade Plant Characteristics
Appearance
The jade plant, also known as Crassula ovata, is an evergreen succulent with a visually appealing, tree-like appearance. It features thick, woody stems and oval-shaped leaves that grow in opposing pairs along the branches. The leaves have a rich jade green color, with some varieties showing a yellow-green hue or developing a red tinge on the edges when exposed to high levels of sunlight[1].
Growth Habit
Jade plants have a slow growth rate, typically gaining about 2 inches in height per year[2]. With proper care, they can reach heights of 3 feet or more when grown indoors[3]. They prefer temperatures between 65ºF and 75ºF, and do not tolerate temperatures below 50ºF. Jade plants require a moderate amount of water and can experience leaf drop if they do not receive enough[4]. Additionally, they do not require much fertilizer, making them relatively low-maintenance houseplants.
Native Habitat
Jade plants are not frost-tolerant, and typically grow best at room temperature, such as 65ºF to 74ºF[5]. They are native to South Africa and Mozambique, where they thrive in well-draining soil and sunny conditions. In their natural habitat, jade plants can tolerate occasional droughts and have adapted to store water in their leaves and stems to survive these periods. Because of their native habitat, they are well-suited for indoor cultivation as houseplants, especially in areas with similar temperature conditions.
Cactus Characteristics
Cacti are unique plants known for their distinctive characteristics, which differ from those of a jade plant. This section will provide a brief overview of the essential features of cacti, focusing on structure, adaptations, and distribution.
Structure
Cacti typically have a thick, fleshy stem, which stores water, and small or absent leaves, reducing water loss through transpiration. The stems have areoles, which are small, cushion-like structures where spines and flowers emerge. Unlike jade plants, with their woody stems and oval-shaped leaves, cacti are adapted for water storage and conservation.
Adaptations
Adaptations enable cacti to survive in harsh environments, particularly arid and semi-arid regions. They have a shallow root system that can rapidly absorb water during rare rainfall events. Another adaptation is their ability to perform a specific type of photosynthesis called Crassulacean Acid Metabolism (CAM), whereby carbon dioxide is absorbed at night, minimizing water loss. Jade plants, on the other hand, can survive in somewhat dry conditions, but they are not as drought-tolerant as cacti.
Distribution
The cactus family comprises nearly 2,000 species, and with just one exception, all are native to the Americas. They inhabit a wide range of environments, from deserts to rainforests, and can be found from sea level up to high altitudes. In contrast, jade plants originated in South Africa and, while they are commonly grown as houseplants, their natural distribution is limited when compared to that of cacti.
Similarities and Differences
In this section, we will discuss the similarities and differences between jade plants and cacti, considering their morphological comparisons and growth/care requirements.
Morphological Comparisons
Jade plants, also known as Crassula, are succulents with thick, fleshy leaves that come in various shapes like teardrop, oval, or wedge. They are able to store water in their leaves to help them survive droughts. On the other hand, cacti have areoles, which are small, raised bumps containing spines or flowers (Necps). Jade plants lack these areoles, so they are not considered cacti. While both plants can have a somewhat similar appearance, their structural differences set them apart.
Growth and Care Requirements
Both jade plants and cacti are known for their low-maintenance nature and their ability to thrive with minimal attention. They are often considered beginner-friendly plants.
Jade plants require well-draining soil with a pH range of 6.0 to 7.0. They prefer bright, indirect sunlight and consistent watering with a good drying period in between (Necps). When repotting jade plants, it is recommended to choose a pot that is only slightly larger than the previous one to prevent root shock (rePotme).
Most cacti plants require similar care to jade plants. They also prefer well-draining soil and do well in bright, indirect sunlight. Cacti need less frequent watering than jade plants and can tolerate longer periods of drought (The Spruce).
In conclusion, while jade plants and cacti share some similarities in appearance and care requirements, they are distinct types of plants due to their morphological differences.
Common Confusions
When it comes to succulent plants, there is often confusion surrounding the classification of jade plants and cacti. Both types of plants share similar features, such as their ability to store water in their leaves, stems, or roots, and their preference for well-draining soil and dry environments. These similarities often lead to misconceptions about their taxonomy.
Jade plants, scientifically known as Crassula ovata, belong to the Crassulaceae family, containing more than 1,000 species, including sedums and echeverias. On the other hand, cacti belong to the Cactaceae family, which encompasses around 1,500 species, including the popular saguaro and prickly pear.
While both families fall under the broader succulent category, they have distinct characteristics that set them apart. For example, jade plants typically have smooth, thick, fleshy leaves with a tree-like structure, while most cacti are characterized by their spines and cylindrical, segmented stems (The Spruce).
Another notable difference is their native habitat. Jade plants originate from South Africa, where they grow in rocky, arid regions. Cacti, in contrast, are predominantly found in the Americas, with a few exceptions that can be discovered in regions such as Africa and Madagascar.
It is important to understand these differences in order to properly care for each type of plant. Jade plants, for instance, require moderately moist soil and indirect sunlight, while cacti typically prefer more sunlight and even drier conditions.

My name is Daniel Elrod, and I have been houseplant love ever since I was 17. I love how much joy they bring to any room in the home. I’ve always been amazed at how a few pots of flowing leaves can turn a drab and sterile office into an inviting place where people love to work at.
