Rob has said that it is difficult to get the same flower for Humpty Doo with a leaf therefore the plant is chimera.

Hummmm.... I've put down lots of leaves for Humpty Doo and they're turn out blue and white like they're suppose to. However, this last batch did have 2 that turned out all blue, so I assumed they were just sports. Just don't tell my plants, I want them to keep putting out the blue and white flowers.

He doesn't call it a chimera on his site now. I may have some on leaves. I hope they turn out right.

Sounds like the plant has an identity problem. Interestingly, I'm seeing Humpty Doo sold as the regular blue and white, but I'm also see it sold as all blue.
