Mother's Day Gift Ideas

My parents are replacing their front garden with a front porch. My mom says she can't take care of the garden anymore because it hurts too much. She's not in terrible shape, but she gets really bad back pain while weeding.

I was thinking for mother's day I might buy her a raised planter box so she can grow flowers on their new porch once it's installed. But that also seems a little utilitarian to give her as a mother's day gift. Does anyone have ideas for things I can give her instead of or in conjunction with a planter?
