Also known as Mexican Flame Leaf, Christmas Star, Painted Leaf, Lobster Flower
Wild poinsettias thrive as rangy perennial shrubs along the Pacific slopes of Mexico, displaying fiery crimson bracts to attract hummingbirds and insect pollinators during the dry winter. The vibrant red displays are specialized foliage that shelter cyathia, which are compact, cup-shaped floral clusters bearing droplet-like nectar glands. The milky white latex flowing through its stems protects tender tissue by acting as a mild deterrent against browsing herbivores.
Milky sap can irritate skin and cause mild stomach upset in pets; wash hands after handling.
Why it is dangerous
Diterpene esters present in the milky white sap can cause mild localized skin dermatitis and trigger drooling, nausea, or vomiting if chewed by household pets.
How to recognize a risky encounter
Look for sprawling woody branches with dark green ovate leaves crowned by bright scarlet leaf-like bracts surrounding small yellowish cyathia.
What to do
Keep ornamental potted plants out of reach of dogs and cats, and wash exposed skin immediately with soap and water if latex contacts bare hands.
Responsible observation
Pruning: Wear gardening gloves when trimming to avoid direct contact with the sticky white latex.
Lighting: Provide bright, indirect sunlight and shield foliage from cold drafts below 10 degrees Celsius.
Watering: Soak soil thoroughly only after the top layer feels dry to the touch.
