Problem: Creeping Charlie (Lawns)
Lysimachia nummularia Also called moneywort or creeping Jenny, this weed invades areas of the lawn where grass won''t grow because of shade and constantly moist soil. It is a perennial weed that reproduces by creeping stems that root easily at their joints wherever they touch the soil. It also reproduces by seeds. Creeping Charlie is sometimes planted as a groundcover in shaded, moist rock gardens.
Improve the soil drainage.
