Etymology

Nicotiana, named after Jean Nicot (1530-1600), a French Ambassador for the King of France to Lisbon in 1560, who sent the first tobacco plant to France. Simulans, mean similar, possibly alluding to the similarity of this species to other Nictotiana species.

Plant description

Herb to 1.2 m, with glandular hairs. Leaves mostly basal, to 23 cm long and 12 cm wide; elliptic, narrowly to broadly winged. Stem leaves narrowly ovate or elliptic. Inflorescence an erect panicle-like spike with tubular white flowers. Flowering between May and October.
Fruits are brown ellipsoid to ovoid capsule to 13 mm long. Seeds are brown reniform seed to 1 mm long and 0.5 mm wide, covered in small tubercules. Seed embryo type is linear, fully-developed.

Seed collection and propagation

Collect seeds between September and December. Collect mature capsules that are brown or turning a pale straw-colour and contain brown seeds. Can collect individual capsules or break off the whole fruit spike. Place the capsules in a tray and leave to dry for one to two weeks, then rub the capsules gently by hand to dislodge the seeds. Use a sieve to separate the unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. From one collection, the seed viability was high, at 95%.
