nice links! very useful, thanks! the red rim on 'Rubra' is beautiful, but 'my plants' certainly do not have it!.
h-mm.. my 'Rubra' surely looks like 'Red vein' (hence i thought it might be a dup...in db).
but i have a tag too from bot garden. and just verified that their pdf mentions B. nelumbiifolia 'Rubra' too in that same spot , plot 112 - Moos Sunken garden. that's all i have to go on. of course, it can be a mistake on their part...
@eclayne I'll leave it to the specialists to decide
what to do...
