This sundew has long thread-like leaves, which gives this plant its common name, dewthread. After a long winter dormancy, long thin leaves slowly rise from the resting bud, standing tall and proud in the late spring sunlight. Small drops of nectar glisten ever so slightly in the bright morning hours, enticing insects to taste its sweet offerings. By summer’s end, the plant is flecked with trophies of its conquests.

In winter, the leaves will die back, and the plant will form a resting bud sitting at soil level. Growth will resume in mid-spring.

    Incredible Specimen

    Posted by Brian Cooper on August 18, 2020

    Upon arrival and removal from it's great packaging I received a very healthy speciment that was actually in flower. It has been out in the sun with the other carnivorous plants I have purchased from Sarracenia Northwest and it is producing a lot of dew. This one happened to have a tiny bonus sundew near the base of it that must have self seeded there.
