Here is a picture of coffee plant that I am presently trying to keep alive (it is not a happy coffee plant).
Coffee beans, are not “beans” they are seeds — the pit from the coffee fruit. You can plant unroasted coffee beans, and they will sprout. The germination rate is low, something like 5%, so you have to plant several of them, and coffee can’t realistically grow in the climate of the United States. If you wanted to harvest and process your own coffee, you would have to keep your plant indoors and give it a lot of warmth and a lot of sunlight all year round.
But still, it is fun to remember that coffee is produce. It is a fruit. Hence, it is rich with antioxidants and bioflavanoids and continually linked to health benefits.
