I purchased this seed online in 2018. This year I managed to get 2 of the seeds to sprout. Has anyone heard of it. I have no idea what kind of hibiscus it is or if it is even one. The plant is about 8 inches tall and has been growing for about 2 months. TIA

I have not heard of it. This is all I found:

It may be sold with just a commercial name as I did not find patents for it either. Some wholesalers develop plants with no patents or trademarks at times.

Thanks @luis_pr
That is where I purchased it. I wasn't sure the plant even looked like a young hibiscus. Most show a hibiscus with substantially darker leaves. Wasn't sure that mine were the correct color (juvenile) or shape.
