Dwarf snapdragon (A - stand of plants in a strawberry field;
B - plant with flowers and seedpods).
Stems & Roots: Stems erect, 10-40cm
(4-16in.) high, usually much-branched throughout, glandular-hairy;
leaves alternate (1 per node), sometimes in tufts along the stem,
short and very narrow; flower stalks slender, 1-2cm (2/5-4/5in.)
long, from leaf axils throughout the plant.
Flowers & Fruit: Flowers resembling Toadflax in shape but much smaller (6-8mm, ¼-1/3in. long), and light blue to purplish with a yellow spot; seedpods nearly spherical, about 5mm (1/5in.) in diameter. Flowers from June to September.
Habitat: Dwarf snapdragon occurs throughout Ontario usually in cinders and gravel along railway rights-of-way but occasionally in other waste places, cultivated fields and gardens, and has recently become a common weed in many strawberry fields.
Similar Species: It is distinguished by its small, erect, much-branched, somewhat sticky-hairy stems with short, narrow leaves often in tufts, and very small, light blue to purplish snapdragon-like flowers.
