Sundew 'Drosera andersoniana'

Drosera andersoniana is a carnivorous plant from the sundew family, growing up to 25 cm in length. Like every species within the genus Drosera, this plant uses its heavy glandular leaves to trap insects for nutrients. The higher the intensity of exposed light, the brighter red the leaves will be. This plant grows from small tubers in the ground. From a central rosette, spoon-shaped, glandular leaves sprout from its tuber. When fully mature, a 25 cm stalk containing small round leaves grows out of the rosette. At the top of this stalk, small white to red flowers are produced. Propagation is most easily done by removal of smaller rosettes or bulbs near the base of a mature plant. Also, harvesting and sowing seeds is possible.

Drosera andersoniana originates from loamy soils and granite outcrops of southwestern Australia. It grows in exposed, moist areas near grassy patches. For optimal growth, the optimal day temperature is around 25 degrees Celsius. In the night temperatures could drop to 15 degrees Celsius. This plant could also be grown outdoors in spring and in summer, but make sure temperature does not drop below 15 degrees Celsius. Place this species in a mineral rich, water retaining medium that lacks nutrients and other dissolved salts completely. Clean peat or horticultural sand are some examples. Provide this species with bright to very bright light conditions such as direct sunlight or strong artificial lights. Prevent this plant from drying out when in active growth. To maintain swampy or soggy conditions, it is possible to place a perforated pot in a tray of water. Always use demineralized water; water containing even a low concentration of minerals could burn the sensitive roots. Fertilizer is best to avoid but it is possible to feed this plant with caught insects once per month.
