Silene latifolia

White campion grows in most open habitats, particularly wasteland and fields, most commonly on neutral to alkaline soils. Despite the wide array of conditions in which campion can thrive, it prefers sunny areas that have rich and well-drained soil.[3] An example ecoregion of occurrence is in the Sarmatic mixed forests.[4]

It is also named the Grave Flower or Flower of the Dead in parts of England as they are seen often growing on gravesites and around tombstones.

It is naturalised in North America, being found in most of the United States, the greatest concentrations of the plant can be found in the north-central and northeastern sections of the country.[5] S. latifolia is thought to have arrived in North America as a component of ship ballast.

In S. latifolia, outbred male offspring were found to sire significantly more progeny than inbred male offspring.[6] This study indicated the occurrence of inbreeding depression in male plants under natural conditions. In female plants, inbreeding depression significantly affects vegetative growth, age at first flowering and total fitness.[7]

Post-pollination selection occurs in S. latifolia.[7] After multiple-donor pollination, it was found that pollen or embryo selection likely reduces the occurrence of inbred progeny.[7]

The Ojibwa use an infusion of the alba subspecies as a medicine.[8]

Silene latifolia is afflicted by the fungal pathogen Microbotryum violaceum, which acts as a sterilizing sexually transmitted infection in this species.
