Harvest Tips

Wear gloves when handling as sap can irritate skin. Prune back to 12 inches in early spring to rejuvenate growth.
Fun Facts
- 🌱 Bonfire spurge is a cultivar of the poinsettia plant (Euphorbia pulcherrima), bred to be hardy in colder climates and to thrive in garden conditions rather than requiring indoor potting like traditional poinsettias.
- 🌱 The intense orange-red color is not produced by true flowers but by modified leaves called 'bracts' that surround inconspicuous true flowers, similar to how poinsettia bracts appear red.
- 🌱 The plant's milky sap contains diterpene esters that can cause skin irritation and gastrointestinal upset if ingested, so always wear gloves when handling and keep away from children and pets.
