Another spice that I'm trying to grow for myself is cloves. It comes from a tree, something I never knew or even thought about until I moved to Hawaii. So a few years ago I bought an itty-bitty clove sapling, barely 12" high. To my surprise, it lived. In fact, it's doing great. It's close to 8' high now.
The part of the tree that is used for spice is the flower bud. To date, my little tree hasn't produced even one flower. I assume that's because it is still too young. But now that it's getting bigger, I'm beginning to look forward to my first very own cloves.
