I feel like I've maybe been handing out my 5 star ratings too freely lately, but I was really entranced by this book so I'm sure it deserves it. Plant magic isn't the most unique magic system I've ever read about (that one might have to go to Margaret Rogerson's Sorcery of Thorns) but it's definitely not an extremely common one and still really interesting to read about, especially when it's a more magical realism-type story and is set in a modern setting with real life plants (both the normal ones and most of the poisonous ones). Kalynn Bayron said she was inspired by Little Shop of Horrors, which I unfortunately have not seen yet, but am intrigued by after reading this. 
One thing that was a very pleasant surprise to me was the one scene that referenced House of Leaves! That was not something I expected to read in this book, or in any other to be honest, but you should've seen me when I read it. I was crying laughing at the randomness and kind of absurdity of that book, of any other horror novel that could've been mentioned, being brought up. 
Another thing I really didn't expect, because of how overall uplifting (if a little mysterious at times) this story is, was how emotional it got after a certain point. I don't know what the deal with me or the books I've been reading lately has been but they've all made me at least tear up.
