Nelumbo, I have some bad news, none of it will handle being left in the pond over Winter. What some do here in the US for the nelumbo is dig them up and over-winter the tubers inside in the crisper drawer of the refrigerator. The lilies that you mentioned, one is African and the other is Australian. Both are tropical and won't survive your Winters. If you can keep them indoors, that would be best. If they produce corms, which I don't think they do, you could collect them and keep them in the house. That the best help that I can give you.

Thank you, Pondmaninal!
Just few weeks ago, when the temperature of water was 5 degrees C, I went swimming (it was VERY COLD) and I brought my two nelumbos out of the cold water to a basement. I left one nelumbo under water, let's see, what does the winter do..

Hi!

Now I have same question about Nymphaea Juno.. Some weeks ago I looked for Nymphaeas in Google and I found that N. Juno's hardiness zone is 4-10 and mine is 6a. When I saw the picture of it, I thought that Juno is tropical. Is it true?
And didn't understand: When the water temperature is +4 degrees but air temperature is maybe -10...-20, will the tropical waterlily as Juno? survive? Is there a difference between air and watertemperature? (my English may be wrong, because I'm Estonian)
Thanks!

Nelumbo, I had Juno when I moved from Florida to Alabama. It did not survive the Winter up here so well. The corms never came back but I still have some of them that are still hard. I will see if they come back next year. If you get Juno, make sure that you have plenty of room for it to spread. It's a pretty good size lily.

Hi!!

Finally it's spring!! Snow is almost gone! Now, I'm growing Nelumbos - watch my blog: www.tammelill.blogspot.com I know, that they are so big, and one of it, has so much water. But today I'll plant them, and pour the water to the sink (look my blog's first post, last picture - too much water(I got a helpful tip)). Hope my Lotuses grow well and see, how big they will grow. PS. I have three Lotuses from last year. One is in my lake, and two of them are in my cool corridor.
