Happy New Year from the Conservatory of Flowers! January Building Closures for Maintenance. A friendly reminder to our Conservatory Community as the greenhouse will be closed to the public during our annual scheduled building closure from January 16 to January 23. The week-long closure will make it possible for San Francisco Recreation and Parks Department’s electricians, engineers, painters, metal workers, masonry workers and carpenters to complete projects that will continue making the Conservatory of Flowers an exceptional place of beauty. We thank you for your patience during this annual scheduled closure. Doors will be open again on Tuesday, January 24 at 10:00 a.m.
