Some resources note that the leaves and flowers of Portulaca grandiflora (Moss Rose) contain oxalates and are known to cause acute oxalate poisoning.
This species, Portulaca oleracea (Purslane), is sometimes consumed, but no data on the toxicity of Portulaca oleracea could be found in the literature. However, the plant does contain cardiac glycosides and oxalic acids, which can be toxic.
We tend to err on the side of caution in PlantFiles, and the danger notation in the details above is to caution gardeners, parents and pet owners to look further for more information.

Portulaca
There are about 100 species of semi-succulent annuals or perennials in this genus, indigenous to the warm, dry regions of the world. The fleshy leaves vary in color from white to green or red, but it is for their flowers that they are grown--cup-shaped, white, yellow, apricot, pink, purple or scarlet in color, and resembling roses in form.
Cultivation: They are easily grown in all climates. In cooler areas they should not be planted out until the danger of frost has passed. Because they are plants of the deserts they need sun, well-drained soil and only occasional watering. Propagate from seed in spring or cuttings in summer. Check for aphids.
Portulaca oleracea (Purslane)
The oldest member of the genus in cultivation, this is a sprawling annual with small, fleshy leaves that are not in the least decorative. An annoying weed in many warm climates, it has a long history of being eaten as a salad vegetable; it reputedly has a high vitamin content.
Zones 9-11.
