"Intermediate Evening-primrose is a stable derivative of Large-flowered Evening-primrose, O. glazioviana (female) and Common Evening-primrose, O. biennis (male). It is constant in appearance and can occur in absence of parents. Back-crosses can occur."(Stace 1995)
The Evening-primrose group is a difficult one, which is further complicated by hybridization. Where possible a specimen should be checked by an expert to confirm identification.
