There are lots of dwarf Nicotiana on the market, in a variety of colors, but tall, white-flowers Nicotiana sylvestris is still an attraction. Nicotiana sylvestris grows about 5' tall and supposedly gives off a perfumed scent in the evenings, when its flowers face upward. I�ve never seen that happen. But I still grow it for the dangling white tubular flowers that grow in clusters and jingle in the breeze.
