How about gifting your friend a stylish indoor planter or a cute plant pot? You could also give them a book on houseplant care or a subscription to a monthly houseplant delivery service so they can continue adding to their plant collection. Another idea would be to create a care package for their plants including fertilizer, pruning shears, and some cute plant markers.
Or you can get her/him a star map with an important date you share.
