Europe; has naturalized in much of the United States.
Gardens, lawns, landscapes and other moist sites. It will also grow in cracks in the pavement.
It’s not uncommon to see purslane growing with other weeds, such as spotted spurge (shown at right and lower left). Photo by S. Donaldson.
Summer annual (sprouts in spring and summer)
Reproduces by seed. One plant can produce 240,000 seeds.

Once established, common purslane can be very difficult to control due to the large number of seeds produced, so preventing establishment of this weed is essential. Control should focus on removing seedlings before flowering occurs.
Dig, pull or hoe plants. The weed can reroot after cultivation, so it is essential to remove pulled material.
Mulching with landscape fabric or 3 or more inches of organic mulch to exclude light can be effective. Soil solarization can help reduce the number of seeds in infested garden beds during hot summer months.
A sawfly eats the leaves of the plants, but has not provided good control in our region. Large amounts of purslane can be toxic to livestock and people.
Spot‐treat seedlings or young plants with broadleaf‐selective herbicides. Use a surfactant according to label directions. Pre ‐emergent herbicides may be used to manage sites with many seeds.
