Creeping Daisy, a native of tropical Central America, is a creeping, mat-forming herb with pretty yellow daisylike blooms. It has become naturalized in other tropical areas of the world where it has escaped cultivation. When the stems of Creeping Daisy touch the ground, they take root and spread, forming a dense ground cover. In some areas the plant is considered invasive, displacing native plants.

This plant has become a ground cover in my back yard, trailing through half of the lawn, where it's displacing the sod. It started with a single node leaf cutting that I first grew in a hanging basket. It eventually escaped the basket and took root in a flower bed, spreading to the lawn. That's not necessarily a bad thing because it doesn't seem to need the water and fertilizer the sod requires!
