I'm currently working on setting up the system to support multiple cultivar names for one plant.
I can do this a couple ways, so we have a choice to make here:
1) We can keep the system the way it is (where the plant has a cultivar field in the main name) and additional cultivar names can be added the same way that common names can be added. This method would leave the main "Cultivar" field as it is. You would have to make a decision which cultivar name goes into that field, and then any additional ones go into the extra fields created.
Or
2) We can remove the cultivar name field altogether from the plant name information, and instead set up cultivars to be exactly like common names. You would have the cultivars all grouped together, and whichever cultivar has the most thumbs-ups becomes the primary cultivar name that is displayed when you're browsing plants, etc.
I think the second choice makes the most sense, and is consistent with how we're handling common names, but I'd love to hear feedback, especially from moderators and those who will be using this multiple-cultivar-per-plant feature.
