Depends on the relationship, I think. And the distance. Covid is a reliable excuse. Send an actual plant the recipient can keep in their house with a kindly worded message.
Thanks @debianlinux , it's an old friend that I had been close with for many years. I am looking for a reason to bail, then that will lead to me heaping guilt on myself. I'm guessing I won't enjoy my day whether I go or not.
I skipped out on my maternal grandfather’s funeral this year over distance and COVID. The sense of relief when I sent the plant and knew I was taking the best care of myself possible was palpable. You don’t have to feel guilty for taking care of yourself.
Funerals are for the living to help provide a sense of closure. Do what you need to do for you. Your friend knew how you felt about your relationship. Sorry for your loss.
