Portulaca grandiflora is a succulent flowering plant in the purslane family Portulacaceae, native to southern Brazil, Argentina, and Uruguay and often cultivated in gardens.[2][3] It has many common names, including rose moss,[4] eleven o'clock,[3] Mexican rose,[3] moss rose,[3] sun rose,[5] table rose,[citation needed] rock rose,[5] and moss-rose purslane. Despite these names and the superficial resemblance of some cultivars' flowers to roses, it is not a true rose, nor even a part of the rose family or rosid group; rather, it is much more closely related to carnations and cacti.
