It is all agreed that the Arabica plant's native and original home is Ethiopia.

The mythical account:
he coffee plant, Coffea arabica, originates in Ethiopia. According to legend, the 9th-century goatherder Kaldi discovered the coffee plant after noticing the energizing effect the plant had on his flock, but the story did not appear in writing until 1671 and is probably apocryphal.
The National coffee association acknowledges this:
"Coffee grown worldwide can trace its heritage back centuries to the ancient coffee forests on the Ethiopian plateau. There, legend says the goat herder Kaldi first discovered the potential of these beloved beans.
The story goes that that Kaldi discovered coffee after he noticed that after eating the berries from a certain tree, his goats became so energetic that they did not want to sleep at night.
Kaldi reported his findings to the abbot of the local monastery, who made a drink with the berries and found that it kept him alert through the long hours of evening prayer. The abbot shared his discovery with the other monks at the monastery, and knowledge of the energizing berries began to spread.
As word moved east and coffee reached the Arabian peninsula, it began a journey which would bring these beans across the globe."
However was this discovery associated with Cushites or not?
