It is a tall plant, growing to 1.5 m (4.9 ft) high by 0.5 m (1.6 ft) broad. The leaves are simple, somewhat sticky, with the blade partially surrounding the stem, clasping petiole.[citation needed] Flowers are produced on many-branched stems. The flowers are tubular, white, borne in racemes held above the foliage. Flowers can be over 7 cm long with a face 2 cm wide. Their intense scent is strongest at night, to attract pollinating moths. Each flower eventually produces a large quantity of small seeds. [citation needed] This plant is thought to be one of the parents of Nicotiana tabacum, the plant used in modern tobacco production. However, all parts of N. sylvestris can cause discomfort or irritation if consumed.[citation needed]
