Fun Facts
- 🌱 Ivory Bells is also known as Persian Shield in some regions, though that name more commonly refers to Strobilanthes dyerianus var. atropurpureus, a closely related cultivar with deeper purple coloring.
- 🌱 The striking variegation is most vibrant under bright, indirect light; insufficient light causes the silvery-white markings to fade and the plant to become predominantly green and leggy.
- 🌱 This plant is relatively short-lived (2-3 years) compared to other houseplants, but it propagates easily from soft stem cuttings in water or moist soil, making it easy to continuously rejuvenate your collection.
