What a cool article. Yes, we bought the cinamomum zelanicum or Ceylon cinnamon tree for my friends land, the cassia is the other one that I have heard is used for most ground cinnamon sold in the US. There is a difference in the taste of cinnamon here and in the US, to me it is a noticeable difference. They also sell those long sticks of rolled cinnamon bark in the open markets here, they are about a meter in length (+/-3'). I've heard that it is grown commercially somewhere here on the peninsula but I'm not sure where. I use either cinnamon or cardamom in coffee, also usually some vanilla. When we were traveling in Guatemala I discovered that that country is the 2nd largest producer of cardamom in the world, after India, but almost none of it is sold in the country, it is all exported. I did find some to buy but I would love to have a more constant source.
Since we planted the cinnamon tree last spring, I guess it will be another year at least before we can harvest any. It was pretty small, only a couple of feet tall. I'll have to go out and find it the next time I'm down there and see how big it has gotten.
