Fun Facts

- 🌱 Calathea makoyana exhibits nyctinasty, an automatic leaf-movement behavior where leaves fold up and down throughout the day and night—this audible rustling has earned plants in this genus the nickname 'Prayer Plants'
- 🌱 The leaf patterns are created by selective pigmentation on the upper and lower leaf surfaces, with the undersides typically displaying reddish-purple coloration that complements the green topside patterns
