'''''Portulaca''''' ('''purslane''') is the [[type genus]] of the purslane family [[Portulacaceae]], comprising about 40-100 species (probably much fewer and potentially far far more) found in the tropics and warm temperate regions. It is also sometimes known as '''Rose Moss'''.

[[Common Purslane]] ''Portulaca oleracea'' is widely considered an edible plant, and in some areas an invasive type of weed. Some ''Portulaca'' species are used as food plants by the [[larva]]e of some [[Lepidoptera]] species including [[Nutmeg (moth)|The Nutmeg]].
