Lysimachia nummularia
Also called Herb twopence, Moneywort, Twopenny grass, Twopenny thot, Creeping Loosestrife, Creeping Yellow Loosestrife, Herb Tuppence
Creeping jenny is a fast-spreading, low evergreen perennial with rounded leaves and yellow summer flowers, widely grown as groundcover. It thrives in moist soil and is invasive in some areas, so keep it contained.
Lysimachia nummularia is a species of flowering plant in the primrose family Primulaceae. Its common names include moneywort, creeping jenny, herb twopence and twopenny grass.
The cultivar 'Aurea' (golden creeping Jenny) has yellow leaves, and is somewhat less aggressive than the undomesticated species. It is cultivated as an ornamental plant, for groundcover where the range of its growth can be limited. It is also suitable as a bog garden or aquatic marginal plant. It has gained the Royal Horticultural Society's Award of Garden Merit.
It is native to Europe, but has been introduced to North America, where it is considered an invasive species in some areas. It aggressively spreads in favorable conditions, such as low wet ground or near ponds. It can be weeded by hand, if all stems and stem fragments are removed, to prevent the stems from rooting and regrowing.
