Drosera - Tuberous - Sundews

GENUS: Drosera

A genus of over 100 species of sticky-leaved perrenials (and a few annuals,) distributed around the world in all climatic zones from the Arctic to sub-saharan Africa. Many are easily grown, and make excellent house plants if planted in peat:sand mix and stood in a saucer of rainwater on a sunny windowsill.

Tuberous species

Species requiring completely dry dormancy in the summer, when they die back to tubers, sprouting again in the autumn. A sandy soil of 1:1 or 2:1 sand:peat should be used, and tubers should be planted 1-3" below the surface of trhe soil, with the conspicuous "eye" (the point at which the stolon will emerge,) pointing upwards. Tray water during the growing season (usually October-March or so,) and keep frost-free in full sun, but allow the pots to dry out completely in the summer with complete dessication being prevented by air humidity (a reasonably humid greenhouse will be sufficient, or wrap tubers in a little fresh but dry moss and seal in a plastic bag.) Most spp. produce 1 to several offset tubers a year, which can be dug up and replanted while the plant is dormant. Don't disturb the tubers after the stolon has emerged, and recommence watering when it appears above the soil.

SPECIES: D. auriculata - Common Name: None - Distribution: Australia

Cultivation: as for D.peltata.
