Nicotiana sylvestris belongs in every garden if you sit outside in the evening and adore sweetly perfumed blossoms! 5 foot tall spires are covered with white, tubular blossoms that are closed during the day and open at night to release their sweet scent, attracting night blooming moths as pollinators. I have a patch of this that self-sows for me year after year and I adore it. If a flower blooms at night, it is called a vespertine flower. Grows best in warm soil in sun or partial shade.
