Thread-leaved 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 leaves of this plant unroll in spirals – an arrangement similar to the circinate vernation seen in ferns.

Once the seeds germinate, tiny threads of curved leaves begin to form. The curves are in spiral and proceeds to slowly uncurl as the plant grows. Many leaves are born and they grow tall compared to other Drosera species. Once the leaves are fully grown, they take an erect or semi-erect appearance. Their natural distribution areas extend from the East coast of North America from the Southwest of New Scotland, to the North, through New England to Florida and Louisiana, to the South. They grow in marshy places with poorly-mineralized soil where umidity is constant and sunlight abundant. There are many variations and hybrids, and all were introduced in other places. All of them should be cultivated equally; abundant watering with chlorine-free water and abundant sunlight with a substract consisting of poor-quality soil that can retain water, preferrably Sphagnum sp. moss, live or dehydrated. Rich or semi-rich soil burns the roots, and so does water with chlorine. They do require winter protection if grown in cold weathers as the plant is sensitive to frost, but the seeds need colder temperatures to germinate. To germinate the seeds, they should be scattered onto damp and cold stratification. Sphagnum sp. moss is exceptional at this. The seeds should never be buried as they need the direct contact with sunlight to germinate; this means you should spray water instead of dropping a heavy amount of water onto the substract, as the heavy impact may bury the seeds. The plant can catch prey on its own, with no need of human interference and they can survive with water alone. Drosera filiformis needs a dormancy period. When this dormancy happens, the leaves of the plant will completely wither and die and a hibernacula (a small, brown, dormant bud just at or below the soil level) is produced. Resistance to cold is drastically increased during this stage, which remains for several months. When the temperature grows the plant will re-emerge from the hibernacula and proceed to grow. The leaves are covered with tiny structures that ooze a droplet of mucilage. This mucilage is extremely sticky attractive to insects, which get digested by the plant when stuck through the production of digestive enzymes. The flowers are of a pinkish coloring. The propagation is done through seeds or through leaves in a process known as "leaf-cutting".
