In my office building, the building management changes the decor theme seasonally in their 3 'planters' in the lobby.
About Thanksgiving they changed it from white painted brush (sticks arranged in the 2' square planters, I never really thought much of that display) to 3 white phal orchid plants per planter. The orchids actually did pretty well and most buds opened even though in the drafty lobby. They are fading now and one has crown rot. It was a beautiful display.
Also there was traditional Christmas decorations in the lobby
