Something unexpected pops up in Cosmo's garden. Even amid rare plants, it is miraculous: a parrot tail lily!
As Cosmo concentrates on taking care of the rare flower, he forgets everything else. His whole garden suffers, and eventually, the parrot tail lily dies, too. Was it too lonely to survive?
Cosmo's young niece Nelly reminds the sad gardener about something he has forgotten. The plants need each other and nature around them - just like humans.
