Answer: I'm afraid there are dozens of plants that could be the groundcover your sister is growing. To properly identify it, I'll need a more detailed description. Does the plant flower? What color? What shape? Is it in sun or shade? How large are the leaves and how are they arranged on the stem? (Opposite, alternate, etc.) Are the leaves fleshy or thin? Does the plant send out runners or do the stems root wherever they touch the soil? Whatever information you can provide will help us narrow down the choices. Please submit a complete description through the Monrovia question and answer site and we'll do our best to identify the plant for you.
