I purchased a Poinsettia at a local Grocery Store that has many blue leaves. The leaves are not dyed and some are now changing to typical pink/red color. Do I have a hybrid or recessive color expression? If not, could this be a soil pH condition? Two pictures of plants are attached (I hope since this is my first post :)
usually spraypaint, sometimes a die injected. the sparklies if present are also man made and usually just sprayed on. I havent watched one (a blue point) long enough to see it come back from the abhorent color treatment before, interesting.

Thanks for Reply.
If dye was used it must be systemic since leaves are evenly colored with no indication of surface application. There are no sparkles present. After one week (since purchase), only about half of the previous blue leaves remain. Either the dye is bleaching or the chromoplasts in leaves are now producing red pigment. In any event, everyone who has seen plant remarks on its unusual beauty.
I'm not certain what you have if there's no indication of application, but I know that blue colouration would not naturally occur - as far as I know, there's very little evidence of those kind of pigments within the genus. All I could find with just a touch of blue are a few of the succulent Euphorbia members.
Your blue pointsettia is probably a 'Fantasy' pointsettia- they are dyed and I suspect the dye is bleaching out. If you google fantasy pointsettia, you find it is trend/fad for large garden centers to have fantasy parties to custom color your holiday plant.
Making plants something they aren't like this would be another example of catering to a culture that is divorced from plants and nature. For the same reason garden centers diversify into non-plant items to stay open, landcape contractors feature paving, waterfalls and stonework over planting, and a certain other gardening discussion web site is full of links to non-gardening topics.
Seasonal potted plants like poinsettias are grown to be thrown away after the holiday they are associated with. So the whole exercise has a certain aspect to it already, that isn't much impinged by dying the plants or putting sparkles on them.

Re: Blue Poinsettia?
With the Photo of the Day, it is very apparent to me that different people like different things (and sometimes it surprises me). And some people really like novelty, particularly if it is a conversation-starter (as this must be in the first few years of its release - and evidenced by the folks here).
As it happens, I'm in general agreement with the offered opinions. However, my big picture beliefs are that there is definitely room on these forums for people who are keen to learn about pigmentation of blue poinsettias, even if blue poinsettias are not to everybody's tastes.
Tim, I've noted you haven't posted any other replies since last week. If it's because of the responses to this question, please don't let these discourage you from participating on the forums. If it's not, then I've slipped into my bad habit of reading too much into things, and I apologize for speculating.
