Drosera filiformis aka Threadleaf Sundew
Taxonomy
Drosera filiformis, also known as the thread-leaved sundew, is a small, carnivorous perennial herb that is native to the Atlantic coastal plains of the United States. It can be found growing in freshwater areas, seepage bogs, fens, sandy depressions, and moist swales between dunes. This plant is unique within its genus because of its long, erect, thread-like leaves that unfurl spirally. The leaves are covered in red, gland-tipped hairs that exude a sticky substance to trap and digest insects. In summer, thin flowering scapes up to 10" tall emerge from the base of the rosette, bearing multiple pink to purple, 0.75" diameter flowers. Mature plants will form offsets and slowly fill a 1' area in ideal conditions.
As a houseplant, the thread-leaved sundew is a fun challenge to grow and requires lots of water to thrive. It does best in direct, long-lasting light and should be less than 1 foot from a window. It prefers soil that is well-draining and belongs to the Drosera genus. This plant is native to Nova Scotia to the Eastern United States.

Difficulty
If you're looking for a plant that offers a moderate level of challenge, Threadleaf Sundew is a great choice to test your gardening skills.
Soil
Threadleaf Sundew loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.
Lighting
Threadleaf Sundew requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Dewthread is always in the right place to thrive.
Dormancy
During the cold period, it is common for Threadleaf Sundew to go dormant, resulting in a slowdown of growth. To accommodate this, waterings should be spaced out more.
Toxicity
Ploi lacks confirmed information on the toxicity of this plant. If you, a relative, or your pet accidentally consume plant material with unknown toxicity, it's best to consult a medical expert.
Growth-pattern
New growth will sprout from the top of the Threadleaf Sundew as it grows vertically.
