Drosera filiformis

(63 reviews) Write a Review
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 suns rays and enticing insects to taste its sweet offerings. By the end of summers, the plant is flecked with trophies of its conquests. Leaves on adult plant often approach 8 inches. In winter, the plant will die back and form a resting bud sitting at soil level. Growth will resume in mid-spring.

    Drosera Filiformis

    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.

    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.
