60 centimetres tall

Disturbed ground, ditches, marshes, meadows, riversides, roadsides, waterside, wetland.

Flower:
Yellow, 4 petals
 
Small-flowered Wintercress produces clusters of small, bright yellow flowers with four petals arranged in a cross shape, typical of the brassica family. The flowers are about 4–6 mm across, significantly smaller than those of Common Wintercress (Barbarea vulgaris). They bloom from May to July, mainly in moist or disturbed areas such as riversides or damp meadows.
Fruit:
The fruit is a slender, erect silique (a type of pod), usually around 2–4 cm long, with a narrow, beak-like tip. It contains several small, round seeds which are dispersed when the pod splits open along two seams. The fruit matures in summer and helps distinguish this species from similar wintercresses.
Leaves:
Leaves are pinnately lobed, meaning they have a series of lobes arranged on either side of a central midrib. The basal leaves are larger with rounded lobes and a terminal lobe that is often much bigger than the side lobes. The upper stem leaves are more slender and often clasp the stem. The whole plant is hairless or slightly hairy, with a slightly glaucous (bluish-green) tone.
Fragrance:
The plant has no notable fragrance in flower, though the crushed leaves may give off a mild mustardy or cress-like scent, particularly when young and fresh. This aroma is more evident when the plant is handled or bruised.
Other Names:
American Wintercress, Small-flowered Yellow Rocket, Upright Wintercress.
