Caudex plants are a group of plants that store water in a swollen stem or root system called a caudex. This adaptation allows the plant to survive in arid or semi-arid conditions. Caudex plants come in a variety of shapes and sizes and can be found in both indoor and outdoor settings.

Some examples of caudex plants include Adenium, Pachypodium, and Cyphostemma. Adenium, also known as desert rose, has a thick, bulbous base that is often used for bonsai or container gardening. Pachypodium, also known as Madagascar palm, has a spiny trunk and branches that resemble a cactus. Cyphostemma, also known as vinegar plant, has a woody stem and produces grape-like clusters of fruit.

Caudex plants require well-draining soil and should be watered sparingly to prevent root rot. They typically prefer bright, indirect sunlight but can also tolerate some shade. Some species can be propagated by stem cuttings or by seed.

Caudex plants can add an interesting and unique element to any plant collection or garden. Their unique shapes and textures make them a popular choice for bonsai or other forms of plant art. However, it is important to note that some species of caudex plants can be toxic if ingested, so caution should be taken when handling these plants.
