I think diamond dusting is the flowers sugars crystallizing , all my flowers with diamond dusting get attacked by ants while others without it seem to be left alone. I've also tasted one of mine that was loaded with dust and it taste a lot like cantaloupe while others I've tasted seem to taste more like a slightly sweet loose leaf lettuce. I wish I was still getting blooms on my Fiji so I could send you some pollen. it is by far the most diamond dusted flower I have.
I'm just not 100% sure if it is Fiji because mine looks different than the others in the database but it could be a sport or Fiji
