Go to Lake Flondor, next to Grana to farm all colors. There are about 4 seperate fields of Violet flowers and no mobs. Don't forget to take the quest from a Villager sitting on a bench just behind a field of Violet flowers near the center. Also - if you are in a guild, switch to the other 2 guildservers without CD to farm again. Normally there won't be any other players to farm here.

If you just want the 100 ones for the quest to unlock the artisan gathering skill. Go to DalBeol Village and go up the temple. Where in the map have a orange icon. Up there there's 4 spots for gathering these. And just change servers and gather it.
