Trying to find a source for a bi-color dahlia I saw. I've looked at a few reference books and I think it may be dahlia pinnata.

The one I saw was red, with pinnate petals, like echinacea has, then on top of the red petals there was an inner circle of smaller, white petals.

I tried searching for a retail source in the Hortiplex and didn't get any sources. Wonder if anyone knows where I might find this plant for sale.

Thanks so much for your help.
