I just bought this plant over the weekend and looked it up in the database to add it to my Plants List. I think there are duplicate entries, but I'm a novice at plant names in general so I'm not sure. The plant tag that came with the plant indicated it was Caryopteris x clandonensis 'Inoveris' with trademark name Grand Bleu. However, there are two entries in the database - one with 'Inoveris' as a cultivar name and another with 'Grand-Bleu' as a cultivar name vs the trademark name for 'Inoveris'. As a side note, the plant itself really caught my eye - very pretty in full bloom right now. I have a photo I can upload to the database.
