Available to ship May 22. Why do we grow this old time trailing Lantana? Well this species, L. montevidensis, a native to Montevideo, Uruguay, seems to be in bloom forever without any deadheading to speak of. Where it is hardy in zones 8-10 plants can form a low 1-2’ shrub and since it does spread, it works well as a ground cover. For us here in New England, this a terrific easy care spiller for containers where it stays under 8″.
