I found this on SCNA forum and I want to share this with you all. Since not all of us aware of how many variety of cocopop there are, this Euro cocopop varieties standard should help you focus on the variety you want to work with on your project. I am currently working on the Bronze tailed Silver neck double laced variety myself. For those of you that have access to SCNA forum, here is the link if you want to read more about it.
