- 🌱 The lobed edges of the leaves resemble an arrow shape, which is why Alocasia plants are sometimes called 'Elephant's Ear' plants—the lobes look like ears.
- 🌱 Red Shield is a hybrid cultivar (Alocasia × amazonica 'Red Shield'), meaning it was bred in cultivation and doesn't occur naturally in the wild, making it a prized specimen in modern houseplant culture.
