If you are looking for a tough plant it's hard to beat lantana. Lantana are heat tolerant, use little to no supplemental water in the landscape, will tolerate less than ideal soils and usually don't need to be deadheaded. If you are looking for a plant that will thrive on neglect, lantana is the champ. -Provenwinners.com
It is a spectacular plant and very tough. But in NZ it is in group referred to as 'The dirty dozen'.. classed as noxious as it can get into our native bush and take over.
