I have something similar as well, I got from the market in Thailand. Extremely consistent and good flowerer strong as old boots, lovely colour and shape. Will also readily produce many shoots from corms and corms with the slightest stress, even just float the plant for a week and small crowns will develop along the rhizome. Its what they call "Star of Siam" in America , seems to be the standard Purple/blue with mottled pads in Thailand and other parts of Asia. Very nice a real "keeper". Think its that one at least.
Post another picture when the plant has matured and is sending up bigger flowers.
