Does anybody remember what plants Francis Mayes described in the Tuscan gardens in her books?

I saw some dwarf meyer lemon trees and eureka lemons on sale, but I don't have enough time to read through her books to see if she mentioned dwarf meyer lemon trees before the sale ends.

I remember she mentioned dwarf Citrus plants in terra cotta pots, but I don't remember which Citrus variety she mentioned. I have an enclosed courtyard, so I was looking for a citrus plant to grow in a pot that would be fragrant and that would give a mediterranean vibe.
