A House Plant Named Yasemin (2019)

At the funeral of her uncles, Yasemin hits the comforting lie they cherish on her sister's face: She knows she will not recover, so she will stop treatment and not torture herself any longer. Not willing to accept this, the older sister soon realizes that she is struggling with a sense of possession. Her dilemma will be solved by her relation with the cactus they have stolen from the funeral home with Yasemin.
