Fun Facts

  • 🌱 Hoya memoria-christinae is named to commemorate a person and is relatively rare in cultivation, making it highly sought after by collectors of variegated tropical plants.
  • 🌱 The waxy flowers of Hoyas are called 'porcelain flowers' because of their glossy, ceramic-like appearance and are often fragrant with a sweet scent.
