Oh my! I sure learned a lot with that question! First, I thought I was in the phlox database and I was not.
I learned it is called "Phloxes". Hmmm, I thought "phlox" was already in the plural form, so that was also a lesson. That was my first mistake and a big one.
Let's add to the fact that when I typed in "Phlox" I did not realize that any plant with the word "phlox" will come up!
Then I learned my confusion was multiplied by the fact common names can be the same for plants in different genera. I learned the plural for "genus" is "genera". All this started from wanting to earn an acorn by placing an image of Phlox, Intensia Blueberry (genus: Phlox, cultivar Intensia Blueberry,) in the plant database. Well, From that I learned if you enter the first image of a plant, you get 2 acorns. Surprise!
Alls well that ends well!
