Moneywort Common Names: Creeping jenny, creeping yellow loosestrife

Description: Rounded leaves and creeping habitat distinctive throughout growing season.

Habit: Herbaceous creeping perennial growing to 60 cm (1.3 ft), forms dense low mats ranging from 5-10 cm (2 in) in height.

Leaves: Opposite, rounded, resemble small coins, simple, 0.25-1.5 in long, occur on short petioles, upper surfaces have widely scattered, glandular, red to black dots.

Stems: Stalk about the same length as the leaves.

Flowers: Yellow in color and dotted with dark red; 5 petals (occasionally 6), 3/4-1 in wide, stalk about the same length as the leaves, solitary from the leaf axils; blooms June through August.

Fruit and seeds: Small capsule, 1 celled, spherical, splits vertically. Seeds very tiny, 0.5 mg, elliptic and 1 mm long. Capsule may contain 1-5 seeds.

Habitat: Native to Europe and western Asia. Found in open wetlands, floodplain forests, wet meadows, and along lakes, ponds, rivers and streams.

Reproduction: Vegetatively by stems, unknown mechanism for dispersing over longer distances; fragments may be dispersed by water.

Similar species: Common gypsyweed (Veronica officinalis); Ground ivy (Glechoma hederacea); Partridgeberry (Mitchella repens) are all similar in their creeping nature, not when flowering.

Monitoring and rapid response: Hand-pulling when practical, making sure to remove all stem and root fragments; prolonged submergence; establishment of native grasses to shade it out; No chemical herbicides have been found effective.
