Horticulture of the Blue Court.... Hang on....

[Alice looks through the stack of books that she's holding. A few are related to horticulture, but none are the one he's looking for.]

No, but the room I found these in had mostly botany related books and there were too many for me to carry so the one you want may still be in there. I could show you after I drop these off, if you'd like.
