Why is Robusta called Robusta?

The coffee species Coffea canephora, better known as Robusta, gets its name from its hardy characteristics. The plant is more resistant to various diseases and can thrive in harsher conditions than other types of coffee, especially when compared to the Arabica coffee bean. It can be grown at lower altitudes and is less susceptible to pests and diseases. Hence the name "Robusta", which means something like "robust" or "resistant".
