Those “Flowers” Aren’t What They Seem
When you look at the tips of the stems, you’ll see what looks like vibrant yellow flowers. However, our eyes are playing a bit of a trick on us! Those yellow parts are actually “bracts” (specialized leaves). The actual flowers are much smaller and sit right on top of those colorful bracts.
Warning: The Sap is Toxic!
Cypress Spurge is classified as moderately to highly toxic. The real danger lies in the milky white sap, which contains substances that are extremely irritating to the skin. This sap leaks out whenever the plant is cut or broken.
Safety Tip: Always wear gloves and long sleeves when handling this plant. You should also wear eye protection—if the sap gets into your eyes, it can cause severe inflammation and, in the worst-case scenarios, even permanent blindness. Handle with care!
