Crassula Ovata, by Tony Covatta

Grandma rode home with the kids from a family funeral.
“Gran, what’s that potted plant by Uncle Rocco’s gravestone?”
“Rocky was our first at college. The day he arrived, his roommate already had a jade plant in their room. Rocky loved it. His roommate’s mom gave him his own at graduation.
“He always kept one, his charm, he said, for his luck in life, good jobs, finer things, his nieces and nephews. He paid to have one decorate his grave in summer and be housed in winter. The money comes from the same fund he set up for your education.”
