I saw a complete collection of floral materials in the early stage. There are many introductions and habits of floral materials, which is a good book. Advanced books can be found in Pim Van Den Akker's books, including 7 books, all of which are very good floral design books with strong comprehensiveness. And the book of Alex Choi, the last world cup champion in interflora, is also a good book. There is also a book by Benjamin, the Three Musketeers of Floriculture, which is also very good. There are many books, you can search them. Finally, the book of the first person in floral art, Daniel Oster's book can also be read.
