How about a small china trough of mixed african violets (they do a white one) or mini gerberas, or mini roses just swap them for other things when they fade or go over... or how about an indoor orange (calamondin) beautiful fragrance not musky but rich and sweet, Can't think of any houseplants with small strays of floweres especially for the environment you describe,,,, If it is that hot really only cacti or succulents would do really well but scented leaf geraniums might survive if you remembered to water them
