This is what I think of as a common geranium. It’s Latin name, though, is Pelargonium. The Geranium is not a Pelargonium. Yes, it’s confusing!

Pelargonium has the common names geraniums, pelargoniums, or storksbills.
Geranium has the common name cranesbill and is sometimes called “hardy geranium”.

No, there is no test. I just thought you might be interested!
