This species is similar to Silene cardiopetala, but has narrower leaves and stiffer hairs on the calyx.

Silene grandiflora var. xerobatica W. W. Smith (Notes Roy. Bot. Gard. Edinburgh 11: 224. 1920) has a creeping habit, more crowded, linear leaves, shorter internodes in the inflorescence, fewer flowers, and shorter pedicels. It is perhaps best regarded as a separate species.

Silene grandiflora is cultivated as an ornamental.
