Lysimachia nummularia, commonly known as “golden creeping Jenny,” has bright yellow-gold foliage and makes a great low-growing, groundcover.
It is very hardy on the High Plains, can survive limited foot traffic and does best in rich well-drained soil. It can take partial shade, but produces the best leaf color in sun.
If you have a large patch it is easy to divide for easy multiplication of plants for free. Try it as an annual to trail over the edges of pots and tubs. The golden foliage is so bright, it rivals the brightest yellow flower.
