Plant Description
Yellow fieldcress is a perennial herbaceous plant that normally grows about 20–50 cm (8–20 in.) tall. The plant is found growing in disturbed wetlands, muddy or grassy borders of ditches, soggy meadows, floodplain areas, poorly drained areas along railroads, waste places, nurseries, along streams, near cultivated fields, wet lands, along ditches, damp areas, plains, valleys, sandy beaches, gardens, flower beds, park lawns and roadside embankments. The plant prefers full sunlight, wet to moist conditions, and a mucky soil with abundant organic matter. Temporary flooding is tolerated, although more or less permanent standing water is not. This plant can also withstand occasional mowing. Root system produces abundant rhizomes and vegetative offsets of the mother plant; sometimes a prostrate lower stem will form rootlets near the leaf axils on moist ground. This plant often forms colonies.
Stem
Stems are erect to ascending to prostrate, usually branched, ribbed, hairless or with sparse hairs on the lower stem. The lower stem of this plant has a tendency to sprawl along the ground in the absence of supportive vegetative; otherwise it is more or less erect. Both the lower and upper stems are glabrous, angular, and somewhat succulent. Plants can form dense colonies from creeping, underground stems (rhizomes).
Leaves
Young plants form basal rosettes that disappear after the first year. Basal and lower stem leaves are glabrous, pinnately lobed, and oblong-ovate or lanceolate-ovate in outline. The terminal lobe is often broader than the other lobes. They are up to 8 inches (to 20 cm) long and ¾ inch wide, deeply divided into lobes that may be further lobed or have coarsely toothed edges. Leaves are hairless and become smaller and the divisions narrower as they ascend the stem. The margins of the leaves are bluntly dentate, shallowly lobed, or undulate.

Flower
The upper stems terminate in racemes of yellow flowers. These flowers bloom near the apex of the raceme, while the siliques on spreading pedicels develop below. Each flower is about 1/3 inches (8 mm.) across when fully open, consisting of 4 yellow petals 3 to 5 mm long, rounded, spatula shaped, and 4 yellow green sepals. Stamens are 6, erect, 4 larger and 2 smaller. Filaments are yellow, glabrous, to 3mm long. Anthers yellow, 1mm long. Ovary is cylindrical, green-yellow, glabrous, 2mm long in flower, superior. The blooming period occurs from early to mid-summer and lasts about 1½ months.
Fruit
Each fertile flowers are replaced by many seeded, linear, slender silique up to ½ inch (10 to 15 mm) long on a slender pedicel about 1/3 inches (8 mm.) long. Each silique is straight or slightly curved, terminating in a short beak. Fruits are initially green turning to brown as they mature. Fruit consists of several tiny seeds that can probably float on water or blow about in the wind.
Other Facts
- Seed is produced 2 to 3 times per year
- Plants spread by growing additional shoots from the crown or from the roots.
- Creeping field cress has the potential to become a serious weed in greenhouse, container and field ornamentals.
- It has been confirmed in container and greenhouse crops in California in 1998.
- Seed-eating pet birds such as canaries also relish the seeds.
- Other historic uses include various medicinal applications, with varying degrees of effectiveness.
