Answer: The northern facing window boxes can be planted with impatiens, begonias (either fibrous or tuberous) or ferns. The east facing windowbox might hold cascading Lobelia, Fuchsia, Ivy....actually I'd try any annual you liked here to see what would tolerate that exposure. Remember to observe this box throughout the day. Does it get sun up to 8 hours or just in the morning or afternoon? Keep it well watered and fertilized twice a month for best growth and flowering.
