So it seems there is a lot of confusion over these names among various vendors, and you can see in this database entry a few different bloom forms. All those names have also been added to this entry but they aren't all correct.
Dahlia 'Peaches and Cream'
This is the look and description I see most often.
In the database entry above, I think most are the same cultivar, even with some color variations, but they seem to at least have more of a decorative form. Maybe some aren't quite fully open but the petal forms are still similar.
The ones that seem off in color and form, yet seem like perhaps from same vendor, are:
And not sure about these either:
According to the DahliaWorld website, there are all of these registrations.
I am having trouble deciphering them but I think I got parts of it.

The first one, Peaches & Cream, a yellow-pink bi-color Single over 2" Water Lily
The second one, Peaches 'n' Cream, a pink Large Semi-Cactus?
The 3rd, Peaches and Cream III, I assume MinD means Miniature up to 4" Decorative? Orange-yellow bi-color, from the Netherlands.
The 4th Miniature Decorative pink, an oldie
The 5th Single over 2" Decorative Yellow-orange bi-color
The 6th, very old, probably not in commerce anymore.
#7 no info
Anyone have any input to try to clear this up?
Then again, I could be totally wrong and this is one of the dahlias that can show crazy looks until it settles in.
