Hi Keriann, havent seen you here for a while. I read the title and thought - Well just google green Dahlia! So I did, and got some beautiful pics but none of them from places that sell them. I'll keep an eye on this thread hoping someone else knows. Or, if you find them elsewhere, please share the info. Chartreuse flowers are a favorite of mine.

So I tried mandolls method, and didn't even find a picture that looked real (well, they look real, but when you point at them the title says "hairclip" or "art poster"). The only one I found (I only scrolled through a dozen pages, though) that might have been real--it was a photo by someone in Germany that had other, real, dahlias in his list of photos--might not have been, as he also had a blue dahlia that was clearly photoshopped.
So my advice would be to look up as many of the dahlias in the "yellow" list of dahlias as you can and see if any of them are more green than yellow. Happy hunting!

Here is a link that might be useful: Yellow dahlia list

I love green flowers too! The closes I have is Brookside Cooly which has a slight green tint to the light yellow. In fact, I had lost the name for a while and I nick named it "Limey". Its not really green but beside other yellow dahlias it looks more toward green then toward gold.

If anyone finds a true green dahlia please let us know!

Thanks all.

I will keep looking and let you know if I find anything!

Frost warnings already and it was 97* three days ago!

Ok, I contacted Swan Island Dahlias. They confirmed there are no true green or blue dahlias....

Bummer!
