Orchid Naming
If your plant has been tagged with Phalaenopsis Aphrodite 'Plantation' -
then you have is a species Phalaenopsis with a cultivator name.
Phalaenopsis = Genus (first letter capitalized)
aphrodite = species (first letter not capped)
'Plantation' = cultivator's name - is the name given by the cultivator to a plant that has won an award for showing this orchid
This orchid, as I have researched, is designated with HCC/AOS meaning that it has been awarded by the AOS (American Orchid Society) the Highly Commended Certificate and all divisions of this plant will be recognized in this manner.
I hope this clears your confusion
Here is another picture to further help you identify your orchid -
