Fun Facts
- 🌱 Polly's striking white veins contain calcium oxalate crystals, which give the leaf its distinctive appearance but also make the plant toxic if ingested—the name 'Polly' comes from the plant's popularity as a collector's piece among plant enthusiasts.
- 🌱 Alocasia plants are sometimes called 'elephant ear' plants because of their large, textured leaves; Polly is a compact cultivar bred specifically for small spaces, reaching only 12-18 inches tall indoors.
- 🌱 In its native tropical rainforest habitat, Alocasia plants grow as understory plants beneath taller trees, which is why they thrive in the bright, indirect light of indoor environments rather than full sun.
