I was just doing some research on spirea recently and will post a link below on the different varieties. There is a Goldflame Spirea but can't find a Flaming Gold Spirea there but there is a Flaming Mound.

Here is a link that might be useful: spireas for the prairies

Well I just went to the site that supplies the Spirea in question and apparently it does not exist. That is what it said on the label but not the plant in reality. So it has to be either Flaming Mound or Goldflame. Judging by the shape of the shrub, my guess is Goldflame. The website is www.northerngemscollection.com
