So, after doing some research, I found a species of coffee tree that survives in Eastern Canada. Since new england is not that different from Eastern Canada in terms of climate, it seems like it would be a good fit. The variety is the Kent tree(See here: https://www.greenbarnnursery.ca/products/black-locust) which provides roastable bean pods as well as leaves that can be used to brew tea(here is a sample product: https://www.wizemonkey.com/pages/coffee-leaf).
Adding these seems like a fairly straight-forward task, however I can’t quite figure out how to get multiple drops out of a harvest option for a tree. Any advice? I’d perfer not to take the ‘seed’ route, as it is a tree.
