Description
Drosera gunniana is stem-forming tuberous sundew that begins with a rosette, then sends up a stem with shield-shaped leaves. The stems can grow to over 1’ tall and dark red in color under bright light. The small whitish flowers readily self-pollinate and produce lots of linear seeds. It can be easily distinguished from Drosera auriculata by the hairy sepals and oblong seed (compared to glabrous sepals and linear seed). This form comes from Conara in Tasmania, Australia.
Tuberous sundews come from Western Australia and grow during the cool and wet winters, dying back to underground tubers in the hot and dry summers. In around October-November, the tuber will send up a thin stem that emerges at the surface with a bud of new leaves, creating a fresh rosette in about a week. This plant needs to feed and store energy in its tuber and the leaves/stem will turn brown and die when the rain stops and the soil dries out by around May.
While they are the most beautiful of all the Sundews, tuberous sundews are also the most challenging to grow. Their seasonal requirements are strictly necessary and understanding proper moisture through the dormancy period is critical. Unlike most bog plants, these prefer better drainage and slightly drier soils.
This listing is for a single tuber — roughly 3-5mm in diameter. This should grow into a flowering sized, mature plant. They can have a small stem already pre-empting the growing season which should be handled carefully and planted facing up. Plant these ~1.5” deep and keep dry until roughly September-October. The tubers can be stored cool, dry, and dark during summer but must be planted before the growing season.
NOTE: These are for experienced growers. Live arrival is guaranteed but everything afterwards is the grower’s responsibility. If there are any issues from shipping, message me immediately with photos.
Climate: Mediterranean (SW Australia). 40-85F, low to moderate humidity. High temperatures can cause the plants to prematurely go dormant.
Light: Full to Part Sun or 15W per sq ft LED light. Tuberous sundews love bright light but do not require as much as other sundews.
Water: Distilled or Reverse Osmosis water. Sitting in 0.5” of water using tray method.
Soil: 40% Peat: 60% Perlite/Sand is a good mix. Tuberous Sundews like well draining soils and less moisture than bog plants. Rinse media with distilled or reverse osmosis water to remove excess salts.
Feeding: Feed leaves with Insect Powder every couple weeks or so. Tuberous Sundews need to feed regularly during the short winter growing season to gain size and to produce a healthy tuber at the end of the season.
