Répartition :
Native to South America and widely introduced elsewhere, including North America, Asia, Africa, eastern Europe, Australia and New Zealand (CABI 2022; USDA-ARS 2022). In the United States it occurs mainly in the eastern and Midwestern states (Kartesz 2015). In Canada, it occurs generally in Ontario and Quebec and is rare in British Columbia, Nova Scotia and Prince Edward Island (Brouillet et al. 2010+; Darbyshire 2003).
Habitat and Crop Association :
Habitat et Cultures Associées :
Nicandra physalodes grows in cultivated fields, old fields, gardens, roadsides and disturbed areas (Scoggan 1979; Gleason and Cronquist 1991; Darbyshire 2003). It infests a wide range of crops, including cereals, Glycine max (soybeans), Phaseolus vulgaris (beans), Zea mays (corn), Sorghum bicolor (sorghum), Gossypium hirsutum (cotton) and vegetables, as well as pastures, orchards and vineyards (Holm et al. 1997; CABI 2022).

General Information
RENSEIGNEMENTS GÉNÉRAUX
Nicandra physalodes has been reported to produce an average of 16,000 seeds per plant, and be as high as 40,000 seeds (Holm et al. 1997). Seeds are dispersed by water, soil movement and as a contaminant in grain and birdseed (Holm et al. 1997; CABI 2022). Seeds can remain viable in undisturbed soil up to 15 years (Holm et al. 1997).

Identification Tips
CONSEILS POUR L’IDENTIFICATION
D-shaped seeds that are compressed in edge view is a common seed shape in the Solanaceae. The combination of a glossy orange or brownish-orange colour, thick, wavy ridged reticulation and deep interspaces is characteristic of this species. Other seeds in the Solanaceae generally have thin ridged reticulation, shallow interspaces, and are a shiny yellow colour.
Additional Botany Information
AUTRES RENSEIGNEMENTS BOTANIQUES
Flowers/Inflorescence
- Flowers are bell-shaped and pale blue to white in colour (CABI 2022)
Vegetative Features
- Plants are 1 – 2 meters in height with ribbed stems and alternate leaf arrangement (CABI 2022)
Similar Species
ESPÈCES SEMBLABLES
Similar species are based on a study of seed morphology of various species, and those with similar dispersal units are identified. The study is limited by physical specimen and literature availability at the time of examination, and possibly impacted by the subjectivity of the authors based on their knowledge and experience. Providing similar species information for seed identification is to make users aware of similarities that could possibly result in misidentification.
Physalis pubescens L. (husk tomato)
Physalis pubescens seeds (length*: 1.6 – 3.5 mm; width: 1.4 – 2.1 mm) are generally larger than Nicandra physalodes, but the size ranges do overlap. The seeds are glossy yellow or orange with wavy ridged reticulation and longer interspaces near the hilum, compared to orange or brownish-orange seeds and the uniform interspaces of N. physalodes.
* Note: minimum and maximum of 10 seeds in a normal range of this species using image measurement (ISMA 2020)
