Over the past couple of months I've really gotten into making quality cocktails. I could never find a good place to buy mint, so I decided to grow my own mint. I am not sure what type of mint I've been growing, by pictures it seems to resemble some sort of spearmint. Anyway, upon further research, I've found that mojitos call for cuban, or "mojito mint", and mint juleps call for "kentucky colonel". Is the difference substantial enough to start growing these different varieties? What are your thoughts on all of these different varieties of mint?
