Creeping Jenny is thought to be invasive in most of the United States. However, many people still plant it in their gardens because it makes nice ground cover. It is hardy through zones 2 to 10, so it can stand a lot of climate variety. In warmer climates, creeping Jenny is an evergreen instead of a perennial. However, in colder climates, winterizing creeping Jenny is needed. Winter care for creeping Jenny is very simple though.
Continue watering creeping Jenny as normal until the ground freezes. Creeping Jenny likes moist soil and thrives in damp environments. If your creeping Jenny is in a drier part of your garden, add extra water as winter approaches. If your creeping Jenny grows near a pond, no extra steps are needed.
Trim back creeping Jenny's flowers if any are remaining. Also trim off any dead or damaged foliage. Leave only the green foliage on your creeping Jenny.
Spread your creeping Jenny over other perennials after the first frost if they are nearby. Creeping Jenny will act as a natural mulch and keep the ground warm for the flowers beneath it. Remember to remove the creeping Jenny in the spring before if takes root and crowds out your other flowers.
Allow creeping Jenny to die back naturally in the cold and leave it alone. In USDA Plant Hardiness Zone 5b and lower, creeping Jenny turns brown for the winter, but it will come alive again in the spring.
Stop watering creeping Jenny once the ground has frozen. Do not water it again until the ground thaws out in the spring.
