Drosera filiformis

(74 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.

• Acclimated for outdoor growing.

    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.

    Bought during winter

    Posted by Wary San on April 22, 2021

    Bought these guys during late winter. It came nicely packed with a brochure on what to expect. The plant was small and didn't look like much but as spring came a long it doubled then tripled in size just as the brochure said. Good stuff with good directions.

    When i received my plant it was packaged very well and arrived in perfect shape. It was just coming out of dormancy. Against advice, I placed it in a terrarium for about a week then moved it in front of a sunny window. I'm slowly acquainting it with the great outdoors and full sun. We are still getting some pretty chilly nights. It is doing great!

    Drosera Filiformis

    Posted by Susan on April 16, 2021

    Arrived very well packaged, very secure and well tended. Placed them outdoors as the day was bright and sunny. Within a few short days, the "coming out of dormancy" sundew was growing and already catching gnat type insects. Now, a month later, the sundew is about 5" long and loving our buggy environment. Thus far, the BEST nursery I've dealt with. Thank You Jeff and Jacob.

    Wonderfully sticky and fast growing!

    Posted by Laurie Martini on April 15, 2021

    Ordered one of these lovely plants in 3/2021. It was barely above the soil. Now, in the middle of April it is steadily growing, is about 6" tall and covered with wonderfully sticky dew. At the moment, it is my favorite of my droseras (I am new to the hobby). Great plant with careful packing & shipping. Thanks!
