Yellow Bartsia - Parentucellia viscosa


An erect, generally unbranched, short to medium, glandular hairy plant. Leaves are opposite, oblong to lanceolate, pointed, unstalked and coarsely toothed. Flowers usually yellow, 16 to 24 mm long in spikes, 2 lipped, open mouthed, the lower lip 3 lobed, the upper hooded.

Identification difficulty

Damp, open grassy places on sandy soils, often by tracks. It normally occurs in drier dune-slacks and in reclaimed heath-pasture, but is also found on pathsides, rough and scrubby grassland and field-borders, and increasingly in re-seeded amenity grasslands and waste places. It thrives on disturbance.

When to see it

Flowering June to September.

Life History

Hemiparasitic annual.
