Don't get me wrong, I like to show off and talk in botanical latin around my friends and it's always a fun to confuse and intimidate anyone who says they want to learn more about gardening but.........it would be sooooo much easier if we could all just get along and pick one name each.
Of course....we kind of already have. That's what the botanical name is for. No matter where you are in the world, the botanical name will hold true while the common name will change from region to region. Take the Manitoba maple (Acer negundo) for instance . I know a whole bunch of people who call it a boxelder or a boxelder maple and yet all four names refer to the same plant.
So do you need to know these confusing names?? I'll admit it's helpful when buying plants because you'll be sure to get the right plant you want, and it can help impress your friends but it's really up to you. No matter what you choose I'll always include at least one common name and the botanical name.
