The flowers in Mushnik's flower shop are poorly taken care of as mentioned in the script. So these wilted flowers perfectly match the ones that had been sold in the show. Customers bought the terrible flowers anyway because of the Audrey Two.
I just offed another succulent plant. I have special talents. Good thing the tulips in my front yard require no care from me to look beautiful. It's probably frightening enough just having to live on my property.
