It's a gloriossa lilly. I can't remember the latin name but it grows wild here in Thailand. Tends to pop up on roadsides and disturbed areas and is somewhat difficult to transplant to where you 'want' it. It has a small bulb/corm and best luck has been marking the plant with a stake and then digging the bulbs after the foliage dies back. There are a couple (at least) variations in coloration; the one in the photo and another that's mostly yellow with just a touch of orange, and very rarely (here anyway) a red version. They make great cut flowers in a vase, lasting pretty well.
