|Natural range of Portulaca pilosa from USDA NRCS Plants Database.|
Common names: Kiss-me-quick, Chisme, Pink purslane
Synonym: Portulaca mundula I.M. Johnston
Portulaca is the old Latin name for purslane, referring to the milky sap. Pilosa is Latin for hairy.
A description of Portulaca pilosa is provided in The Flora of North America.
Portulaca pilosa has small terete leaves and small lavender-pink flowers, while P. amilis has larger succulent flat leaves and large orange-red flowers.
In the Coastal Plain in Florida, P. pilosa occurs on river sandbars, along highways, lawns, disturbed wet sands of river bays, sandy roadways, and dry loamy sand in parking lots. Soil types include loamy sand, sand and fine gravel. Associated species include Portulaca amilis, Chamaesyce, and Solidago altissima.
Under low light intensity and temperatures, flowers can not open, this results in a tendency towards cleistogamy, and encourages selfing.
Seed bank and germination
Portulaca pilosa was observed at the Archbold Biological Station with sweat bees from the Halictidae family such as Lasioglossum tamiamensis.
