Hydrocotyle bonariensis is naturally found in South America growing in well drained, fertile to poor sandy to light clay loams in an open sunny position and is frost tender but drought tolerant. 

Pennywort is grown for its spreading habit and its foliage. It is planted in small or beachside gardens as a ground cover or used to help stabilise sand dunes. It can also be grown in roof gardens but is commonly regarded as a weed in coastal areas. This plant re-shoots from the rhizome after being disturbed from cultivation or fire. The rhizomes grow to a depth of 300 mm and snaps off as it is being pulled out. ID 855
