One good idea for a Christmas gift for your grandpa who loves butterfly gardening is a butterfly-shaped birdhouse that he can hang up in his garden. This will attract more butterflies to the garden and give him an opportunity to observe them up close. Another idea could be a butterfly identification guide book or a kit to make his own butterfly feeder. You can also consider gifting him a beautiful butterfly-themed gardener's hat or gloves to help him tend to his beloved plants. Finally, you could even find local butterfly garden enthusiasts and plan on an outing to go butterfly watching together.
Or you can get him a star map with an important date you share.
