Why Artificial is a Practical Option:
A real fern or trailing plant on a ceiling requires: suspended irrigation with managed drainage (to prevent drip onto diners), grow lighting calibrated to the ceiling height, weekly access for maintenance and dead-leaf removal, structural assessment of load-bearing capacity for wet soil and pots, and ongoing pest and fungal management in an enclosed warm space.
This is the reason that even the most ambitious live ceiling installation can fail. The artificial version delivers the same visual result permanently, from installation day forward, with none of these obligations.
