Amethyst, no it is not called Bachelor's button. They look similar but its not. I finally found the name. The name for "Makhmali" ful in english is Globe amaranth (gomphrena globosa). I am surprised why we nepali did not know the english name of the flower used every year as mala in bhai tika? Some Nepalis call it "Supari Ful" as well.

Actually this information is for raas, a sajha hero.
