When I see the bloom, I am quite pretty sure that it comes from Hung Sheng. The breeding line of the rothschildianum from Hung Sheng tends to have very dark colour and red pouch. However, most I have seen from his breeding tends to have smaller flower size for the first few time bloom. May you advise the size of this dark coloured roths?
In my opinion, it has potential for using to breed for a dark colored big sized roths. A keeper in my opinion. By the way. have anyone used the HS series roths to breed a large flowered roths such as 2135? I am interested to see the outcome.
