[Wikipedia] Eradication Information: If given adequate moisture and protected from direct sun, Baby's-tears may grow prolifically, and is a common weed in many places.[7] It is capable of vegetative reproduction, so to eradicate a problematic or invasive patch, the entire root system of the plant must be dug out and removed, and not only the exposed leaves; roots or pieces of root which remain buried can (and will) sprout new growth, unless water is completely denied to the plant, causing it to dehydrate. Nurseries grow several varieties, including gold, yellow, and white breeds, but the mossy-green type is most popular with gardeners. (link added by Mary Ann Machi)
