Androgynophore 5--8 mm, glabrous. Petals red, 2--2.5 cm; claws narrowly oblanceolate, glabrous, auriculate; limbs obcordate, shallowly bifid, lobes suborbicular; coronal scales orbicular.

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.
