Name: Clammy ground-cherry, Physalis
Other Names: coqueret hétérophylle, cerise de terre
Family: Nightshade or Potato Family (Solanaceae)
General Description: Perennial, reproducing by seed and by deeply penetrating and widely spreading roots.
Stems & Roots: Stems erect, 20-90cm
(8-36in.) high, branched in the upper part, often apparently branching
in 3's (2 branches and 1 leaf petiole) with a flower in the centre;
leaves alternate (1 per node), long-stalked, ovate to somewhat rounded
or diamond shaped in outline, margins smooth or with shallowly and
irregularly rounded teeth; stems and leaves covered with sticky hairs.
Flowers & Fruit: Flowers borne singly in the angles where 2 or 3 stems and leaves come together, drooping on short stalks; calyx at first tubular with 5 short blunt lobes; petals united forming a trumpet-shaped corolla, mostly yellow with a dark purple centre; after blossoming, the calyx expands and becomes bladder-like enclosing a small, sperical, green berry which turns yellowish when ripe; the berry resembles a small tomato and contains many small seeds. Flowers from June to September.
Habitat: Clammy ground-cherry occurs in southern Ontario under dry open woodland, in pastures, cultivated fields waste areas and roadsides, especially in well-drained coarse soils.
Similar Species: It is distinguished by its very deep perennial root, the clammy texture of its sticky stem and leaves, its yellow and purplish flowers produced in the angles between usually 3 or more stems and leaves, and its bladder-like inflated calyx containing a small greenish or yellowish berry.
