Eating a rare flower will aggrow any dino around you, passive or aggressive. this could sometimes be a really bad idea. You could however, use it to tame skittish Dinos like a tapejara or a quetzal. Because eating it will cause them to not run away while you knock them out.
A great way to farm these sometimes hard to find flowers go to swamps.Now if you have a Theri you can spam tickle to any swamp plant to get X or Y seeds idk I forgot.Especially you can get huge amounts of rare flower.I hope this was useful.
Tame up a therizinosuar and bring it to the swamp, you’ll end up getting a great amount really fast. My rates were at 3.2 harvest damage & 5.0 Harvest amount & in mere seconds i had over 1.3K rare flowers
If you eat a rare flower near wild dinos, they will become aggressive towards you for a period of time, as well as anything you meet along the way. Avoid doing so unintentionally, however this can become useful if you need to grab a dinos attention for taming or to lead it somewhere.
To the person who said “ Plz eat them near a giga or a Titananboa and they will be tamed” dude those will chase you until you die so don’t listen to that person. My brother listened to him and he died far from his base with his best tame.
Idk about other maps but like everyone says, go to the swamp and bring your self a tickle chicken aka theri and if on mobile the swipe up using the finer gathering attack and it will give loads of rare flower AND plant species x
