Hi Bathgate

sorry to say it will stay pink ,its stressed because they are or have been too cold or too wet , they revert to the colour of one of their parents. Still looks good to me.

Gg

hmm, well, I've always wanted a pink one; now I want a white one, lol! Thanks

It looks like it started out as a variety with variegated blooms--mainly white, with a few blotches of pink--and the main growing point has re-assorted itself, so that only the pink cells have survived. If you grow leaf cuttings from some of the older leaves, a few of the offspring will be the original color, along with some pink ones, and some that are striped or blotched white and pink.

Thanks for the explanation. I guess I'll have to learn to like the pink. I think I've neglected it for too long now I'm paying the price.

Neglect has nothing to do with it, Bathgate. It's primarily the luck of the draw. There is one way to stack the deck, though:
The upper picture is showing signs of being grown in very bright light. Plants use the pink pigment--anthocyanin--as a natural sunscreen, and cells in the growing point that were able to produce anthocyanins probably were able to multiply faster than the albino cells, gradually crowding them out.

OK so this is a permanent switch? I have it on my kitchen counter with windows on each wall - very very bright light.
Very interesting - thanks for the info. I'll just buy a new one.

Well, like I said, some of the older leaves probably still contain the necessary genes, but salvaging those genes will involve a lot more folderol than just getting a new plant. Hope you find a real beauty! :)

I've tried the leaf experiment. They all went folderol! Nice word lol thanks
