While I know many hybrids can "look" the same/similar in a picture, they may not be the same. Having said that, here is something that might help.... and then again maybe not...
Your Sangyung Ruby is very pretty, Howard.
The bloom of Blc. Sangyung Ruby is larger than mine and their plants also look different.
While I purchased it, the orchid keeper said that this might be a cross of Pot. Sally Tayor.
Since there were so many similar crosses available, it got difficult to find its true ID.
