Joanne,
Adding a new plant entry only:
Genus: Calibrachoa
Species: x hybrida
Editing existing plant:
Botanical name: Calibrachoa x hybrida.
"Another Question: Will the system allow duplicate Trade Names for different entries. Almost every calibrachoa series out there has one that is named "Blue". So we could have 20 different "Blue Trade Name Calibrachoa
What happens if there are multiple "Blue", different series, many without registered patented names."
Ouch! Include the series name in the trade name when warranted. This means a hard and fast rule is replaced by the subjective decision of the moderator.
