I bought it last year and didn’t get its name. It blooms then dies, then repeats next season
It might be Yellow Chincherinchee, Ornithogalum dubium. I used iNaturalist with your photo to suggest and they look pretty similar. You can also try using Seek (an app that uses your camera to identify plants and animals) and with more angles you might get a better result.
Ornithogalum dubium indeed or sun star or star of Bethlehem

Yep, I checked it out and it definitely is a Yellow Chincerinchee. Thank you.
Also the seek app is pretty cool. Thank you!
