The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Taxonomy: available through www.itis.govITIS logo

Identification: Lysimachia nummularia is an herbaceous perennial. It is a low-growing, creeping ground cover which might form leafy mat. Roots where leaf nodes come in contact with the soil. This cultivar features rounded, slightly ruffled, yellow leaves (to 3/4" diameter). Profuse, cup-shaped, bright yellow flowers (to 3/4" across) appear in early summer.   Stems - Repent, tp +40cm long (and sometimes much longer), herbaceous, multiple from the base, typically simple, with 4 wings from deccurent leaf tissue. Wings to 0.7mm broad, forming vertical grooves along the sides of the stems.  Leaves - Opposite, petiolate. Petioles to +/-5mm long, glabrous, with a wide and shallow adaxial groove. Blades orbicular, to +/-2.5cm in diameter, glabrous, entire, somewhat cordate at the base, dark green above, lighter green below. Veins of the leaves impressed above, expressed below.   Inflorescence - Single axillary flowers. Peduncles to +/-2cm long, erect, glabrous.   Flowers - Petals typically 5 (sometimes 6), united at the very base and forming a small corolla tube. Tube to 1mm long. Free portion of petals glabrous, yellow, to +1.4cm long, 5-7mm broad, rounded at the apex, oblong-elliptic. Stamens 5(6), adnate at the base of the petals, erect, united at the base. Filaments yellow, broadest at the base and tapering to the apex, glandular puberulent, to 5mm long. Anthers yellow, to 2mm long. Ovary superior, green, glabrous, globose, 1.2mm in diameter. Style green, glabrous, 5mm long. Stigma small, purplish. Sepals 5(6), green, spreading, with the margins slightly revolute in the basal 1/2, ovate-lanceolate, acute to acuminate at the apex, to +/-7mm long, +/-5mm broad, glabrous.  

It is in flower from May to August, and the seeds ripen from August to September. The flowers are hermaphrodite (have both male and female organs) and are pollinated by bees and flies. The plant is self-fertile.

Size: horizontal stems to 40cm+

Native Range: Eurasia.

* HUCs are not listed for states where the observation(s) cannot be approximated to a HUC (e.g. state centroids or Canadian provinces).


Ecology: Habitats include stream banks, bottoms, seeps, fens, roadsides, ditches, woodland borders, thickets, moist areas of black soil prairies, cemeteries, and edges of yards (Campbell et al. 2010, Forest Service 2013). This species needs moist soils to grow (Missouri Botanical Garden 2012). It can grow in semi-shade (light woodland) or no shade (Missouri Botanical Garden 2012). Elevation ranges between 0-3280 feet.

Lysimachia nummularia reproduces and vegetatively; plant fragments can flow downstream and develop into new plants (IPANE 2013, MISIN and MNFI 2013). As the stem grows horizontally along the ground, new roots develop at the steam nodes (IPANE 2013, Kennay and Fell 2011). North American populations are not known to produce seeds (IPANE 2013).

Moneywort remains green most of the year in the Great Lakes (Kennay and Fell 2011).

Means of Introduction: Deliberate release.

Status: Established where recorded.

Impact of Introduction: Thrives in damp soils which will often kill off other types of ground covers. It is likely too invasive for border fronts or areas adjacent to lawns.
