Not all species of tobacco are banished. Some are even decorative. At least one is scented. "The cool air. The scent of growing things. That is a tobacco plant which you can smell, sir," P. G. Wodehouse observed in Joy in the Morning (1947). Yes, the original white blooming Nicotiana alta from South America is scented when it bloomed at night. Unfortunately, plant breeders have intervened and created more vivid coloured, day-blooming selections lacking scent.
