After days of hunting I finally found the name of a flower I bought about two years ago during the La Trinidad Strawberry Festival. It looks like an orchid but it’s not. After a reverse image search it seems to match the blue flag iris but then it’s a bit off. After many many attempts of finding an exact match and using Philippine Iris as a string, it finally yielded its name. It’s called walking iris (Neomarica northiana) but there’s another catch, it’s not a true iris but some kind of a lily. At last I know what it’s called now. Regardless if it’s an iris or a lily, it’s still beautiful.
