How about a personalized poetry anthology for your wife? You can spend some time searching for poems that match her interests or those that relate to your relationship, and compile them together into a book. You can also DIY a book cover with a nice design, such as a favorite photo of the two of you. Another idea would be to enroll her in a poetry class or workshop, which would allow her to nurture her passion while learning new skills.
Or you can get her a star map with an important date you share.
