- Common names can be easy to remember but confusing when talking about plants on a wordlwide basis. For example, the common name 'Bluebell' is used to describe plants in the Campanula genus. It is also used for plants in the genera Penstemon (North America), Hyacinthoides (Europe), Endymion (Asia), Polemonium, Mertensia and Wahlenbergia (Australia). That is why it is much safer to use the scientific name (if you can remember it!).
