Purslane
Scientific Name: Portulaca oleracea L.
Other Names: Portulaca, Pursley, Pusley, Pussley, Wild portulaca, pourpier potager, pourpier gras
Family: Purslane Family (Portulacacae)
General Description: Annual, reproducing only by seed. A low-growing or prostrate plant with succulent reddish stems, thick leaves and small flowers. Stems and leaves flat on the ground or slightly raised, 2- 3cm (1 in.) high.
Habitat: Purslane is one of the most common weeds in gardens throughout Ontario, occurring also in row crops, waste areas and edges of driveways but not surviving under heavy shade and thus rarely seen in grain fields, hay fields or pastures. The very fleshy nature of Purslane enables it to continue flowering and ripening seeds for several days after being hoed or uprooted. Though rarely producing roots from the stem, if even a small portion of the root of an uprooted plant touches the soil, it can grow a new root system and become re-established.
