traditions

question
My friend and her husband often visited Hawaii. It was their favorite place to visit. On *******, her husband passed away. To mark the one year anniversary of his passing, I wanted to do something special for my friend. Do you know of any Hawaiian traditions or gift that I may give to my friend to let her know that I remember and I care?

Thank you for any assistance you may have to offer.

answer
May I suggest ordering a flower lei she could place on his grave, if she visits one, or if she doesn't, order a collectible (nut, seed, or shell) lei for her to hang at the house or in a 'special remembering place'.
Do a search for 'order flower lei' or 'order nut lei'.
