Fuzzy Purple Flower Plants (Coarse Grass or whatever)

One day my brother found a field which full with purple plants, ok I mean half of that field. He take me to there. Super beautiful. But I don't know what this plants called. Since its so beautiful, so I capture some pics of it plus me as a photobomb. Pardon me, lol. Maybe we can also called it as ilalang ungu in Bahasa. It is so beautiful, and I feel like on Japan or other else coutry.

1. Btw, pardon my photobomb.
