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.

I grow Peaches 'N Cream (that is why my photos in the database look much like the vendors you listed). I believe it is classified as a Mini, Formal Decorative, Bi-color dahlia.

The photos that don't belong under that name look like Peaches and Cream (often sold by resellers or big box stores). It is bi-color as well, but the form is more informal (flouncy petals), and I think the blooms are bigger. There has always been a lot of confusion around the many variations of this name.

Yes, I figured yours was correct and I just did a Google search for Peach N Cream and it definitely shows various vendors with the other coloring as Peaches AND Cream.

Google definitely does not get an A (or even a B or C) for that performance!

It just picks up the main words, peaches, cream.

So after looking at tons of nurseries and other links, it seems the formal decorative pinkish one is Peaches N Cream or Peaches n' Cream. It's the highly desirable one. I found two vendors that mention the intro date of 1993. So I moved all the corresponding photos over to that entry.
Dahlia 'Peaches N Cream'

The other one with the yellow, streaks of pink and white tips is the Peaches and Cream, or Peaches & Cream and is a water lily form. Dahlia 'Peaches and Cream'

I found this posting on Houzz from 3 years ago with pictures of both. Scroll to the post by cicivacation who says "The first is Peaches & Cream, a light blend waterlily that does very poorly in competition and can be found at many big box stores in spring. The second is Peaches-N-Cream, an orange and white bicolor formal decorative that does very well in competition and tends to have touchy tubers for experienced growers I have talked to about it."

So what I copied over from DahliaWorld in my first post is still very confusing with the way they are spelled and with the registration details but I figured that human error can happen over the years, either with the registration or vendor selling. It seems the two are consistent now as far as how the vendors list them.
So now we'll just have to keep an eye out with the two entries to make sure the future submitted photos land in the correct one.

And I am determined to get Peaches N Cream, waiting for a couple of vendors to open in 6 days.

Thanks for cleaning that up, Sue! I hope you are able to acquire it.

This post also nudged me to go check on PNC in storage. Fortunately, the tubers look fine.

Yeah, I bet that "touchy tubers" comment could be a bit alarming!
