Evening-primroses are introduced from North America, but have been grown in European gardens for a long time. Some forms of the plant are unknown in North America, having developed in Europe since the introduction of the genus. The Large-flowered evening primrose (Oenothera glazioviana, also called Oe. erythrosepala) is the species found most frequently on dunes in Northern Ireland. It is established, for example, on dunes in Co Londonderry beside the River Bann estuary.

All names: Oenothera glazioviana Micheli ex C.Martins; Oenothera erythrosepala Borbas; Oenothera grandiflora auct.; Oenothera lamarkiana auct.
