PLANT PROFILE
About Golden creeping Jenny
Golden creeping Jenny (Lysimachia nummularia 'Gold') is a mat-forming, herbaceous perennial cultivar valued for its golden foliage and small yellow summer flowers. It is a marginal/emergent plant that creeps and roots as it spreads, making it useful as edging on a pond margin or bog garden shelf. The cultivar is recorded as evergreen, retaining foliage through the winter, and has a low stature (RHS lists it to about 10 cm for the 'Gold' selection) while forming a wide mat (RHS lists spread at 0.5–1.0 m for the cultivar).
Use this plant at the pond edge or in a container/basket on a marginal shelf rather than as a submerged oxygenator; planting guidance from RHS places this species in the emergent zone (0–300 mm of water) so it is suitable at water’s edge or in shallow water up to about 30 cm deep. Grow in humus-rich, moisture-retentive soil and plant at the same depth as the original container, or pot into a basket for small ponds and pond shelves so runners can be contained.
Golden creeping Jenny has recognised wildlife value and is included on pond‑margin and pollinator lists, but it is also described as very vigorous and may need management to prevent it becoming a nuisance. RHS recommends trimming back wandering stems and using containers or baskets for vigorous marginals to make management easier and to reduce the risk of escape into adjacent damp ground or wild habitats. For the cultivar, propagation is by stem cuttings in spring; the species can also be grown from seed or by division. RHS assigns the cultivar an H5 hardiness rating and notes it is not native as a named cultivar, so treat planting and any escapes with appropriate containment and monitoring.
