Portulaca (/ˌpɔːrtjuːˈleɪkə/,^[2] purslane) is the type genus of the flowering plant family Portulacaceae, comprising about 40-100 species found in the tropics and warm temperate regions. They are also known as moss roses.

Portulaca 'All Aglow'

Portulaca grandiflora 'Bicolor'

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 larvae of some Lepidoptera species including the Nutmeg (Hadula trifolii).

Purslane can be eaten raw or cooked, and lends itself to stir fry dishes. Some say it has a slight lemon-like taste and mushroom-like texture. It is relatively easy to grow in more northern climates, including the New England area in the United States.
