A Peacock Plant's Roots

Who knew that the common Peacock Plant (Calathea makoyana) has such interesting roots? It turns out there are plants in this genus Calathea and another closely related genus Maranta that have a long history of being domesticated as food crops in South America.

These root structures are actually distal tubers, and they are storage organs for the plant to accumulate energy for keeping it alive during periods where growth is reduced or unfavourable, most likely because of seasonal changes in weather.

Interesting what you would find just hidden beneath the soil, no?
