Drosera graniticola

Its greyish-green appearance is quite typical for this erect growing species which makes it easy to identify it even from some distance. Some forms may turn reddish during later stages of the growing season, however. Young plants form a basal rosette from which a glabrous stem with few bracts on the lower part may develop later in the season. In contrast, adult plants never produce a basal rosette. D. graniticola can reach up to 20 cm in height.
The tubers are white. The flowers will open for several days and stay open during the nights. Initially, the anthers are closed and red in colour. When they split open the yellow pollen becomes visible.

I grow this species in 11 cm deep pots which seems to be the minimum (but still ok) as quite often tubers are produced at the bottom of the pot.

Adult plant shortly after emerging from the substrate. The lower part of the stem is covered with a few bracts. The first carnivorous leaves are now active.

Flower pictures taken at different stages. Initially the red anthers are closed. After a certain time (depending on conditions, especially the temperature) they will split open and present the yellow pollen.
The lowermost pictures were taken after pollination.
