i already did in the stacks i just can't get to the actual wall flower like if i stand in front of i can't touch it
If you are in the library, and you can't pick up the wallflower, then maybe you already did pick up this one. Look at your quest log file for this quest. Does it actually say Library Archives? And also, are you sure that it is the wallflower that you are standing next to when you are in there? If so, it sounds like you might have a bug or glitch.
You might want to send an e-mail to firstname.lastname@example.org and ask them to help you get moving along with this quest.
