From the experts:
Camellia is an exotic flower name with distinct roots related to the Camille/Camila group and has varied associations to the moon, water, wealth and perfection. It could be thought of as a floral replacement for Amelia.
The attractive flowering tree was named by Linnaeus for the Moravian Jesuit botanist Georg Joseph Kamel and has been used, if sparingly, as a first name since the 1930s.
In the language of flowers, the camellia denotes admiration and perfection, and it's the state flower of Alabama. The Dumas novel The Lady of the Camellias is the basis of the opera La Traviata and the Garbo film Camille.
