The 'Green Screen' at the HSNY is a series of galvanized metal planters that run in front of the windows, enabling them to have horizontal 'display strips' for their collection of plants. Spreading them out in this fashion allows them to display many plants across their windows and still allow light to flow through.
The design was conceived by Marpillero Pollak Architects, and the variety of vibrant greens and interesting plant shapes come alive when the sun shines through the windows (they are located on the 13th floor and have great southern exposure).
The planters do not have drainage, so there is a bed of pebbles underneath to help the soil dry out. Succulents seem to thrive in this setup. Other small potted plants enjoy the planters with only the pebbles and water acting as a humidity tray. The galvanized planters can be unbolted if necessary for replacement.
If I could take one of these plants home, I might choose the Begonia conchifolia 'Bulls Eye' - it is the one with the red dot where the stems and leaves meet. The red dot glows with the sun behind it!
