Fun Facts
- 🌱 Hoya curtisii is native to Southeast Asia and was named after Thomas Curtis, a 19th-century London nurseryman; hoyas are sometimes called 'wax plants' due to their waxy, long-lasting flowers that can refloom on the same peduncle for years
- 🌱 The plant's silvery variegation intensifies with bright light exposure, making it a dynamic plant that changes appearance throughout seasons and can be used to gauge light conditions in your home
- 🌱 Hoyas are epiphytic plants in nature, meaning they grow on trees in tropical rainforests and absorb moisture and nutrients from decomposing plant material, which is why they prefer loose, bark-based potting media
