Drosera filiformis

(81 reviews)

This sundew has long thread-like leaves, which gives this plant its common name, dewthread. Long thin leaves slowly rise, standing tall and proud. Small drops of nectar glisten ever so slightly, reflecting the sun's rays and enticing insects to taste its sweet offerings. By the end of summers, the plant is flecked with trophies of its conquests. In winter, the plant will die back and form a resting bud sitting at soil level. Growth will resume in mid-spring.

Type of Plant: Outdoor perennial for container growing.
Leaves: Up to 8 inches at maturity.
Sunlight: Partial to full sun during the growing season.
Water: Low-mineral water (50 ppm or less).
Soil: Equal parts peat moss and perlite only.
Winter: Dormant. Minimal protection in USDA zones 7-9. Mulch in colder regions.

• Acclimated for outdoor growing.
• Shipped in a 3-inch pot. Care instructions are included.

    Plant came very well packaged and healthy and unstressed. It recovered and began producing “dew” within a couple of days. It also tolerates central Texas heat, humidity, and light ver well. It is definitely my most robust drosera.

    I have followed the directions and kept in a try of rainwater and distilled water. Growing rapidly in full sun. If you live in a dry climate you can grow this easily. Best part of my day is to see what it caught.
