We'll do what we can to help you name your NOIDs, hopefully they'll be distinctive! There are so many varieties. Make sure you take pictures of the leaves, stems and note if there are side buds as well as when they flower. Were they sold as generic "pink/red/white" or were they just label-less from being late in the buying season? If they had names earlier in the season your nursery's buyer might be able to give the varieties they had last year to narrow your search. Looking forward to seeing the pictures!
