noun
woodland draba; woodland whitlow-grass
A small annual plant in the mustard family, Draba nemorosa, with yellow flowers. Botanical term; in everyday contexts usually referred to by its katakana name.
イヌナズナは春に黄色い花を咲かせる。
Woodland draba blooms with yellow flowers in spring.
The name イヌナズナ literally means 'dog shepherd's purse', from イヌ (dog, implying 'false' or 'inferior') + ナズナ (shepherd's purse, Capsella bursa-pastoris), because it resembles that plant but is not the same species.
