The Crown of Thorns is a resilient, sun-loving succulent shrub admired for its bright, long-lasting blooms and distinctive thorn-covered stems. Its thick, fleshy leaves and continuous clusters of colorful bracts—most often red, pink, or yellow—make it a standout choice for those who want a plant that truly thrives with minimal fuss. When given plenty of light, it can flower nearly year-round, adding a vibrant pop of color to windowsills, sunrooms, patios, and warm indoor spaces.
Euphorbia milii prefers bright light to full sun and grows best when placed directly in a sunny window or outdoors in warm climates. Its succulent nature means it stores water in its stems, so it’s important to let the soil dry out between waterings. Overwatering can cause root issues, while underwatering is tolerated far better. It is adaptable to average household humidity and temperatures but should be kept away from cold drafts.
This plant contains a milky sap typical of euphorbias, so care should be taken when pruning or repotting, as the sap can irritate skin. Its natural, architectural form and reliable blooms make it a favorite for both beginners and seasoned collectors.
Pet Safety: Not pet safe. Euphorbia milii is toxic to cats and dogs if ingested, and the sap can also irritate skin and eyes. Keep out of reach of pets.
