How about a high-quality leather-bound journal with blank pages, a sketchbook, or watercolor paper inside so she can capture her nature observations in a beautiful and personal way? You could also pair it with some quality art supplies such as colored pencils, watercolors, or a set of nice pens. Or, you could look into getting her a field guide or book on local plants or birds to help inspire her journaling. Another idea could be to gift her with a nature walk or hike in a beautiful park or nature area, where she can explore and gather inspiration for her journal.
Or you can get her a star map with an important date you share.
