Some years ago in Atlanta, I visited an orangery - a greenhouse devoted to growing oranges and other citrus trees.
You may imagine my delight in reading about another sort of greenhouse, the "pinery", in Jane Austen's Northanger Abbey. A pinery is a greenhouse devoted to growing, not pine trees, but pineapples. They were apparently quite the rage among wealthy landowners in 18/19th century England.
The heroine in Northanger Abbey is similar to Don Quixote, in that she confuses fictional books with real-life. The book is generally considered a minor Austen novel, but it's minor only in relation to her masterpieces. I think it's a fine introduction to the author's work.
