Drosera filiformis tracyi or Southern Thread-leaf Sundew is among the largest of all the North American sundews. D. filiformis tracyi is slightly larger than D. filiformis filimormis (the Florida Giant Form is slightly larger still). Its long leaves can reach upwards to 18 inches. It is predominately green to yellow-green with clear to slightly orange digestive glands, and covered with numerous sticky tentacles that glisten in the sunlight. It is quite noticeable from a distance and appears to shine silvery-green. It gets a lot of attention at the Nursery. It prefers open, sunny bog conditions and does not grow in Sphagnum Moss. It can tolerate drier conditions than most sundews, and competes well with other non-carnivorous plants. It emerges late in the Spring and lasts throughout the Summer and Fall. It forms a large sturdy winter hibernacula (resting bud), which is best pushed down to the surface in early Spring for best growth. The numerous large flowers are white on tall scapes. It flowers from May to June, and frequently produce abundant seeds. Seeds can be sown immediately or stored for several years. Drosera filiformis tracyi is a dramatic carnivorous plant for your collection or bog garden. In it’s dormant season, it will be shipped as a dormant hibernaculum. Juvenile plants may be shipped. For maximum effect use multiple plants in a 6″ pot.

Drosera sundews can be grown in captivity using the following steps:

  1. Choose the right growing medium: Drosera sundews require a soilless growing medium that is acidic and nutrient-poor. A mixture of sphagnum moss and perlite or sand works well.

  2. Provide adequate lighting: Sundews require bright, indirect light to grow well. A south-facing window or a grow light can provide the necessary light for healthy growth.

  3. Water properly: Sundews require moist soil at all times, but do not tolerate standing water. Water with distilled or rainwater to avoid mineral buildup that can harm the plant.

  4. Feed the plant: Sundews are carnivorous and obtain nutrients by capturing insects with their sticky, glandular hairs. In captivity, you can feed your sundew small insects such as fruit flies or gnats.

  5. Control humidity: Sundews require high humidity to thrive. A humidifier or a tray of water near the plant can help maintain the necessary humidity.

  6. Avoid fertilizers: Sundews do not require fertilizers, as they obtain their nutrients from insects.

  7. Repot when necessary: As the sundew grows, it may require repotting into a larger container. Repotting is best done in the spring when the plant is actively growing.

By following these steps, you can successfully grow drosera sundews in captivity.
