Biology

This plant germinates in spring, flowers in August and produces fruit in September and October. The number of plants at a site tends to vary greatly each year, and the species is a relatively poor coloniser of suitable habitat (3). The main European stronghold of pedunculate sea-purslane is on the Danish Coast, and it is possible that the species was introduced to Essex by geese or other migratory birds, which pass through Denmark when the seeds are ripening (3).
