This plant is a trooper and very useful. It produces endless tiny daisies that are emerge white and mature to shades of pink, rose and red. It will seed itself (reasonably not invasively) into places nobody else would like and then burst into flower from various nooks and crannies. Plant beside your steps, pathways, around your patio or in rock walls or rockeries. From Mexico and Central America.
