Plant Parts

This plant, commonly known as the Crown of Thorns, possesses distinct morphological features that are central to its characterization. The roots form a sturdy anchoring system that allows the succulent to thrive in arid conditions, absorbing necessary nutrients and moisture from the soil. Most notably, the plant contains a specialized internal substance known as latex, a milky, white sap that flows through its stems and leaves. This substance is a key identifying feature of the Euphorbia genus and is often noted for its caustic properties when it comes into contact with skin or eyes.
