Fun Facts
- 🌱 Purple Passion gets its striking color from anthocyanins, the same pigments that make blueberries blue and red peppers red, which are induced by bright light.
- 🌱 Despite being called 'Purple Passion,' the plant is native to Indonesia and is sometimes called 'Velvet Plant' due to its distinctive soft, fuzzy leaf texture caused by fine hairs.
- 🌱 The plant's foliage color intensifies with bright light but it will still grow in lower light conditions, though the purple coloration becomes less vibrant and may fade to greenish-brown.
