Other names:
Portulaca, pursley, pusly, pussley, wild portulaca

Species information

Lifecycle:
Annual.
Propagation:
Reproduces by seed.
Emergence:
Purslane is considered a late-germinating species in the spring since the seeds require high soil temperatures with poor germination under 24° C (Miyanishi and Cavers, 1980).
Habitat:
Purslane is almost never found in grain crops and is much more common in horticultural crops and home gardens.
Competitiveness:
Purslane is not an overly competitive plant because it germinates late in the season and has a prostrate growth habit. It is a succulent and an edible plant.

Often mistaken for

I know it's not Spotted spurge because purslane lacks the oval red “spot” in the middle of each leaflet nor will it exude the milky juice that spotted spurge does when its leaves are removed from the stem.
