How about a grafting kit for Valentine's Day? You could include a selection of different types of fruit tree scions (the cutting that is grafted onto another tree), grafting tape, grafting wax, and a grafting knife. You could also include a book or set of instructions on how to graft fruit trees. This would not only be a thoughtful gift but would also show that you support his interests and hobbies.
Or you can get him a star map with the date of your first kiss.
