I loved hearing about all the different plants and their smells and meanings and powers. The romance was cute, if a bit silly, and the friendship relationships were lovely. Basically everything to do with the plants and making elixirs was wonderfully entertaining and fascinating, as well as descriptions of various gardens, and fulfilled my want for plant magic vibes.
I personally thought the way the main character's mother isolated her made her daughter's entire life about being and aromateur was really gross and a bit abusive. I realize I have a personal problem with parents living out their dreams through their children as if their children are extensions of themselves instead of actual human beings, but this is pretty severe. It is shown to lead to self-esteem issues for the daughter during the book. Plus it was child labor. Just because they weren't making money from it doesn't mean it was okay to work her daughter so hard at home she didn't have time to go to school. Spoilery part:
I think the mother was forgiven for this way to easily. It's shown that she had her own hurts that partially led to her bad treatment of her daughter, but that's why people need to deal with their own issues before having kids. Bad pasts do not justify hurting other people. And you don't get a pass from critically examining your actions just because you're following in your ancestors' footsteps.

" most people don't know that heartache smells like blueberries".
Now that's the way to start a book. A person who can smell people's auras. This book was fascinating. The characters and the storyline wee smart and entertaining. All of the scent terminology was well done and made me wish I had mim's nose!!
