We have a south facing patio area under a glass canopy. There are floor to ceiling walls to the north and east, the south has a waist height wall along the top of which I've planted a dwarf lavender hedge, the west "wall" is completely open to the elements. It's a really lovely area which we use a lot for eating and sitting reading but it needs brightening up a bit. Any thoughts for what will like the extra heat under the glass and do well in large pots?
