About
Drosera graniticola is an erect perennial tuberous species in the carnivorous plant genus Drosera that is endemic to Western Australia. It grows 10–20 cm (4–8 in) high near granite outcrops. White flowers emerge from August to September. D. graniticola was first described and named by N. G. Marchant in 1982. Grow it in full sun and loam and sand soil. In UK gardens it is half-hardy and may need winter protection in colder areas (RHS H3). It works well for patio and container plants, sub-tropical and conservatory and greenhouse. It tolerates acid and neutral soils, moist but well-drained conditions and east-facing, south-facing and west-facing aspects.

About the genus
Drosera, which is commonly known as the sundews, is one of the largest genera of carnivorous plants, with at least 194 species. These members of the family Droseraceae lure, capture, and digest insects using stalked mucilaginous glands covering their leaf surfaces. The insects are used to supplement the poor mineral nutrition of the soil in which the plants grow.
