The number of flowers that start with the letter "J'' is relatively small when compared to the vast amount of flowers in the world. The List of Flowers website, for instance, provides the name of nearly 3,000 flowers, but only 18 of them start with a J. Many of the names of these flowers have Greek or Latin origins and are not easy to remember, which is why a list by alphabet can come in handy.
