About
Drosera ordensis is a perennial sundew of the Drosera petiolaris complex (subgenus Lasiocephala) in northern Australia. It grows around Kununurra at the north-eastern tip of Western Australia and in the neighbouring Keep River National Park area of the Northern Territory, on sandy soils near sandstone outcrops among Sorghum grasses that give light shade. It is named after the Ord River, where it was first found in 1951, and was described by A. Lowrie in 1994. Rosettes are usually about 8 cm across, with plants up to 20 cm reported. Its petioles are broad for the group and densely covered on both faces with long white woolly hairs, ending in round blades about 3-5 mm across. In the dry season it produces small, hairy, semi-dormant leaves, and the dense hairs are thought to collect dew and condensation. It flowers from December to April, opening five-petalled flowers about 1.5 cm across one at a time, ranging from pink to nearly white. Its closest relative is D. lanata. In Japan it appears regularly at online auctions. Cultivation is as for its relatives and fairly easy if kept warm.

Growing Tips
Temperature & Overwintering
Its relatives like the low 30s °C in summer and dislike dropping below 18°C at any time; heat it through winter.
Light & Placement
Grows best in strong light, which shows off the white hairs; weak light makes the leaves stretch.
Watering
Stand small pots in a tray of pure water: higher in summer, lower in winter, even allowing a few dry days.
Soil & Repotting
Grows in pure peat or equal parts peat, sand and perlite; a free-draining mix suits this sandy-soil species.
Propagation
Leaf cuttings do not work and leaf pullings only sometimes succeed; some plants do not divide. To get seed you need two unrelated plants flowering together and hand pollination.
