Fun Facts

🌱 Iron Lady is a cultivar of Iresine herbstii, commonly called bloodleaf, which is named for its vivid red or dark burgundy coloration that resembles blood.
🌱 The plant's striking dark foliage color is a result of high anthocyanin pigment concentration, which actually helps the plant absorb light more efficiently in shaded conditions.
🌱 Iron Lady is extremely easy to propagate from cuttings—simply place 4-6 inch stem cuttings in water and roots develop in 1-2 weeks, making it perfect for sharing with fellow gardeners.
