THREAD LEAF SUNDEW Drosera filiformis
Drosera filiformis, commonly known as the thread-leaved sundew, is a small, insectivorous, rosette-forming species of perennial herb. A species of sundew, it is unusual within its genus in that the long, erect, filiform (thread-like) leaves of this plant unroll in spirals – an arrangement similar to the circinate vernation seen in ferns.
D. filiformis occurs naturally in both Canada and the United States; its natural range extends down the eastern seaboard of North America from south western Nova Scotia in the north down through New England to Florida and Louisiana in the south.
D. filiformis is frequently cultivated in mineral-poor soil and distilled, reverse osmosis, or collected rain water. All types of D. filiformis other than 'Florida All Red' require a winter dormancy for long-term survival, forming hibernacula in the winter.
Plants are hardy in zones 7-10, though are reported to be able to survive in zone 5 with winter protection.
Note: These seeds are extremely tiny! It's just how they naturally are. Reading glasses are recommended to aid with seeing them, even for those who don't normally require glasses to read. The seeds are shipped in either a wax envelope, or folder within a small paper. Open carefully, and sprinkle onto the growing medium. Do not bury the seeds. Germination information is below.
Seeds per pack: 10
Germination: These seeds need a cold stratification period to germinate.
Sprinkle the tiny seeds on top of the growing medium. Do not cover them. Use a mixture of 50% perlite and 50% peat moss. Cover the container with plastic to retain moisture. Place the container in a fridge for 4 to 6 weeks. On removing from the fridge, place in very bright light at room temperature. Once the small plants begin to grow, slowly open the plastic a little each day. Use rain, distilled or reverse osmosis water (use a spritz bottle while plants are small) to regularly water plants, as sundews are bog plants, the container can be placed in a tray of the above mentioned water types to keep soil wet. Generally seeds germinate anywhere from 1 to 3 months, but some stragglers can take up to a year.
