question on Hibiscus sabdariffa

Is this the false roselle. the one with pink flowers, it's also good for making tea with and has a lemony flavor in the flowers right? Soooo, where does one get the true roselle with the yellow flowers, i'm looking for the seeds? I have the Hibiscus sabdariffa pink flowers, but it's never bloomed so I don't know if it's got pink flowers, bought the seed s off ebay last year, the pic on ebay had pink flowers on it.

any help at all on finding the true roselle with yellow flowers would be greatly appreciated

I think the one i'm looking for is this one H. sabdariffa var. altissima
