It’s your fault I bought RedVox albums and have been listening to them off and on for weeks. The whole album “Another Light” fits an early Wallflower I think.

Made myself a little garden to grow myself my only friends  
Got myself a brand new start and, oh no I screwed it up again  
Guess I’m staying up all night; in my mind, but out of sight
 
I’m to blame for this, I hide away until the day is through  
I will pay for this, won’t find a way to push the blame on you  
I won’t run from this; hide away until the day is through
 
Can’t believe my eyes this morning; I found a plot of weeds instead  
Yesterday was so adoring; my god, so easy to offend  
I would rather fly than fight; close my eyes and hang on tight
 
I’m not to blame for this, I hide away until the day is through  
I will run from this, I’ll find a way to push to blame on you  
I’ll be all right tomorrow, hide away until the day is through
 
It’s so simple, It’s as easy as can be  
Make a monster; lock it up, throw away the key
 
In the backyard, buried deep underneath the tree  
There’s a monster taking root in the property  
In the garden, where the weeds are now growing free  
In the garden, where my friends plot to bury me  
There’s a jungle, it’s as far as the eye can see  
Overgrown now, it’s no longer a fantasy  
But it’s too late, by the time that I realize  
I can’t see now, cause the dirt is up to my eyes

And some pot, just for good measure.

Those lyrics seem to be fitting for her character, especially her appearance – considering that her green hair looks like the leaves of a plant.
 
Perhaps she and Twilight would be good friends, considering that the latter also handled plants in Celestia’s greenhouse. Twilight might even ask Wallflower for help in studying plant sentience for her latest experiments!
