Dear Drosera-lovers,
These are two hardy, cold-loving Drosera species (which, indeed are closely related sisters, and which naturally thrive in the cold conditions of the subantarctic southern hemisphere).
Drosera stenopetala, from New Zealand
The leaves formed early in spring are short-stalked and form a flat rosette. Later the season the leaves have longer petioles and are held erect.
The single white flower develops on a long entirely glabrous scape. Interestingly, its pedulous in bud, and the strange sepals are dark green, almost black, with curled and overlapping margins.
Drosera uniflora is endemic to the subantarctic part of South America. These plants were grown from seed originating from the Falkland Islands.
The small white flowers are produced solitary on a scape. Like in D. stenopetala, the sepals are very interesting and unique in the whole genus: they are distinctly petiolate and cup-like.
Usually, plants of D. uniflora are dark red when growing in full sun. However, all attempts of mine to grow this species in full sun outdoors failed so far. The plants really seem to dislike hot summer temperatures. Thus I grow them partially shaded with some of my temperate Pinguicula species outdoors. This results in dull green plants, however they grow well (but awefully slow!).
Both species are kept outdoors under my conditions year round. In winter, they are usually covered with snow for at least 3 months, and stand temperatures down to at least -20°C without problems. However I can only keep the pots outside in winter as long as they are protected by a snow cover, as the plants are not tolerant of freezing. I have already lost several plants from draught and damage due to freezing after some black frosts. Remember that the natural habitats are regions with high precipitation, and therefore are covered by a thick snow-layer all winter.
All the best,
Andreas
