Euphorbia caput-aureum

Euphorbia caput-aureum is a unique and striking succulent plant belonging to the Euphorbiaceae family. This species is native to Madagascar and is valued for its unusual appearance and resilience. 

Euphorbia caput-aureum is known for its distinctive, swollen caudex, which can vary in shape and size. The caudex serves as a water storage organ, allowing the plant to survive in arid conditions.
   
The plant produces cylindrical, often segmented stems that grow from the caudex. These stems are typically green and can be adorned with small spines or ridges. The leaves are usually small, narrow, and short-lived. They appear at the tips of the new growth and may fall off as the plant matures, leaving behind the photosynthetic stems.

Euphorbia caput-aureum produces small, yellowish-green cyathia (the unique type of inflorescence characteristic of Euphorbia species). 

Cultivation:
- Soil: Prefers well-draining, sandy or rocky soil. A cactus or succulent mix with added perlite or pumice for extra drainage works well.
- Watering: Requires minimal watering. Allow the soil to dry out completely between waterings. Overwatering can lead to root rot.
- Sunlight: Thrives in bright, indirect sunlight but can tolerate some direct sunlight. Protect from intense midday sun to prevent scorching.
