Like Thrift, Sea Campion is a halophyte, very salt-tolerant and grows on rocky shorelines near the sea.

It also grows well inland on land contaminated by lead mining, for it is also a metallophyte, able to absorb and accumulate heavy metals without ill effect.

Hybridizes with : Bladder Campion to produce a hybrid which lacks a common name, but the scientific name is Silene uniflora × vulgaris. The above examples are un-likely to be this hybrid since that is thinly scattered across the UK in places far removed from where the photos were taken.

Easily confused with : Bladder Campion which some experts and books think are one and the same thing. But Bladder Campion is more branched and stands more erect.

Despite its name, it can also be found well away from the sea near the spoil heaps from old lead mines and gravestones in North Wales covered in lead-rich stone chippings, for it likes lead. See Thrift for more information re sequestering of heavy metals.
