Floridabear -
you never know until you try - and if you put leaves and grow starters until they bloom - you will know for sure - and you can get your "small fortune" back.

In my experience the sport with time gravitates to only one of the types of the flowers . Right now if you get the leaf from under the pink flowering bloomstalk - you get a pink starter and from under the blue flowers - blue babies.

But again - may be you got lucky and acquired an unique "harlequin" stable plant.

I wouldn't sell leaves, you are risking a bunch of very unhappy buyers.

So - start putting leaves.

I am not sure that if you treat it as a chimera, means top the crown and wait for the suckers - it will help. Suckers grow from buds - and depending what side of the plant the bud comes from - that will be the color of the baby. I am thinking that if you would cut the crown off - you would see the section of the stump having the different color - it's where the blues are coming. Like wedge of the blueberry pie sitting in the cherry pie. The rerooted crown would be blooming the same, but the suckers from the stump - not.

Good luck and enjoy your special plant

Well it is WAY to young to have a crown yet. So I cant get any suckers from it. so I would have to do leaves. And frankly,I have no room to do that. So I guess I will just have to enjoy the odd plant that I have and wait for its next bloom cycle to start. Which is starting now. So in a few weeks I will know if it still has half blue and half pink flowers or not.

You could try to use the blossom stems to propagate. "Other very genetically unstable varieties, like the most unusual multicolor or fantasy-blossomed varieties can also prove difficult to propagate "true" by leaf cutting."
I've added a howto link below.
