Let me quibble a bit more... two quibbles Night before Christmas is a sport from White Christmas. NBC is often described as an improvement over its parent as it has thicker leaves and wider margins. (Those traits make me wonder if it is a tetraploid, though nobody says it is... wonder if anybody has checked.) So quibble number one - NbC can only "revert" (I really wish we'd never started using that word...) to its parent plant, which is White Christmas. White Christmas is a plant with lots of white center and narrow green margins and is typically a very poor grower. If that is what you are seeing, you are correct by current standards in calling it a reversion. You don't say so, but I suspect from your Revolution comments that what you are seeing is a solid colored sport. If that is the case, then... Can a plant "revert" to its grandparent? I think the answer to that question is "no" but I would prefer to ask the question "What is the genetic heritage that my sport is likely to have... what will it likely resemble... what might it be identical to?" Going back an additional generation, we find White Christmas came from Gus Krossa, who said it is derived from an unregistered,unstable, streaky Fortunei-type he called 'Krossa Variegated' (aka [incorrectly] H. fortunei 'Krossa Variegated.' So we can expect a solid colored sport from NbC to be a Fortunei-type plant... most typically green... most typically similar to Hyacinthina... BTW - Gus Krossa (Livonia, Michigan) was a pioneer in modern hosta development. He imported many hostas from Japan from the 1950s-1970s and often gave them names starting with Krossa. Sometimes is was a letter-number, like Krossa A-1, sometimes a registered name like Krossa Cream Edge. He is best known for importing "Krossa A-3" which was registered in his name after his death by Alma Krossa as H. 'Krossa Regal.' In Japan it is known as "Ginba Giboshi." A great hosta - a great tribute. now to quibble number 2 - one that has resulted in no end of aggravation to me, since I like my labels to be correct but I'm also cheap and hate replacing them if they don't need it... You described your plant as Night Before Christmas. It was in fact originally registered as Night Before Christmas. But international naming conventions have clarified that prepositions used in plant names should not be capitalized. I think most of us automatically used non-capitals for of... like Queen of Islip... but before is also a preposition. Thus, the correct name of the plant is Night before Christmas. Yes... people have referred to me as Cliffy... PS Cliffy is a reference to the Cheers character, Clifford C. (Cliff) Clavin, a character co-created by the actor who played him, John Ratzenberger. Ratzenberger originally tried out for the part of Norm. The producers told him they were impressed with him but that he didn't really click for them as Norm. He pointed out that the cast didn't have a "bar know-it-all" - the guy who always seems to know obscure stuff that he enjoys sharing with people, even when they aren't terribly interested in acquiring the additional information. Cliff appeared in 273 episodes of Cheers between 1982-1993. He appeared as an animated character on The Simpsons and made a guest appearance on Frazier. He is now primarily known for his voice work in Pixar animated films - he has a role in every one - but interestingly enough, when he had a speaking role in Richard Attenborough's "Ghandi" his voice was over-dubbed by Martin Sheen. Another interesting tidbit... "Ratz" not only attended Woodstock, but helped build the stage. But I digress...

My undulatas get sun from about dawn until about 1pm. Every year their white centers show the same green misting that your Night Before Christmas is showing now. Some will go almost entirely green. The 3rd picture on the Hosta Library shows a little of this greening effect (link below). I would guess your seeing that greening effect or maybe your NBCs were actually mis-labelled undulatas. Here is a link that might be useful: http://www.hostalibrary.org/u/u.html

I cannot believe it was done in 2004......and so many names that we don't see at RP any more ! That still makes me chuckle. A great way to start the week before Christmas . Thanks Donnamira !

I'm in Texas and it won't stand full sun, but will take morning sun. If you are really good about watering, it helps it stand up to the sun. bk
