I got the plants as seedlings, sold as house plants. There were about 8 in a small mug so I grew on four. I decided to ditch two as I didn't have room for more - as they're tender (anything below 5° & they start to suffer) I have to bring them indoors over winter & they sit under my south facing bay window.
They're in my greenhouse now & I should be able to leave them outdoors from June through to October.
Being sold as novelty house plants, C. arabica I think, the flavour isn't likely to be great, not to mention that I need to figure out how to roast them!
I may try germinating some now I know they'll flower & fruit.
