The rare death flower can’t be found in Sims 4, so you’ll have to graft it instead. Start by grafting a cherry with an apple to make a pomegranate. Then, graft a snapdragon and a lily to make an orchid. Finally, graft the pomegranate and orchid together to make the death flower. You can use the death flower to save other Sims from death when the Grim Reaper visits.
