Detailed Information

Flower: Flower shape: 5-petals

[photo of flowers] Flowers are cup-like in the leaf axils, about ¾ inch across, with 5 bright yellow, round petals slightly tapering to a point, the edges a bit ruffled, and the surface often speckled with deep red dots. 5 yellow stamens and a single pistil, mostly recessed with an erect, slender style, are in the center. The calyx with 5 broadly triangular lobes is hidden beneath the open flower, on a short stalk.

Leaves and stems: Leaf attachment: opposite Leaf type: simple

[photo of leaves] Leaves are evergreen, generally round, ¾ to 1 inch long and wide, in opposite pairs with smooth edges, on a short stalk. Surfaces are also smooth but with faint gland like dots. The stems are hairless, light green, creeping and many branched, rooting at the nodes and forming dense mats.


Creeping Jenny, also commonly called Moneywort, has been popular in the garden trade as a hardy, dense ground cover, especially along shady margins where it blooms most of the summer. A rampant spreader, its can become weedy and when it escapes into natural habitats, its shade tolerance and evergreen characteristics give it great advantage over native woodland species, especially highly valued spring ephemerals. While more than a few gardeners have discovered its highly aggressive behavior to their own chagrin, its greatest potential for damage will be along riparian forests. We are fairly confident this species is under-reported in Minnesota.

This is in the garden of the place we bought last year. I also just discovered it in the woods after taking out extensive buckthorn last winter. It's pretty. I wish it wouldn't spred so much. It'd be a good ground cover.

On August 27, 2015 I ran across a small, sprawling ground-hugging plant in the middle of a trail in the woods near the Castle Rock in far southern Dakota County. It wasn't blooming and didn't notice any fruits. It was only about a half a foot across. I also noticed the same kind of plant(the same plant?) when I was there on May 20, 2015. Wasn't blooming then, either. I see that this would be a new record, if it is Moneywort. As a horticulturist, I'm familiar with the plant but this seemed more delicate with more space between the paired, round leaves. But from each node of the ground-creeping stem I took was a single, thin, straight root. Only later did I realize that I could have gotten a photo and GPS co-ordinates. But, then, it's only a garden escape.

I just discovered a new weed in my yard this year, maybe this. Does it have an almost rubbery feel when you try to pull it, like you're stretching something elastic or rubber?

I bought this for containers, then looked it up. I'm sorry the nursery is selling it, why are they?! Proven Winners. I wish I had looked it up before buying because I will have to destroy it.

About 30 years ago, I first noticed a few Moneywort plants struggling to grow in the lawn next to my neighbor's driveway where the grass wasn't growing very thickly. It eventually spread to the ditch along Basswood Ave. It also grows one block away in the ditch on Stanford Ave, just up the hill from Chester Creek.
