Largeleaf Pennywort

Hydrocotyle bonariensis, the largeleaf pennywort, once a member of the family Apiaceae, now in the family Araliaceae and of the genus Hydrocotyle, is a hairless and creeping perennial.

 ;Flowers: This plant has numerous white to creamy-yellow flowers, and the flower stalks can be 30 cm in height.
Fruits and reproduction: The stems creep and root at the nodes; the plant spreads by rhizomes. Dollar Weed produces a dry dehiscent fruit that, at maturity, splits into two or more parts each with a single seed.
Habitat: This plant lives in sandy areas of somewhat extreme conditions: very dry lands that are flooded sometimes.
