Here's a Sundew from North America. It has long and slender, erect 'tendrils', filaments covered with tiny hairs or trichomes with globules of sticky exudate at their ends. They serve to trap small insects and also contain digestive enzymes that soon reduce insects to plant nutrients. Then it'll have energy to produce these pretty pink flowers.
Our 'elegant species', as writes Frederick Traugott Pursh (1774-1820), was seen by him near Tuckerton, New Jersey, about 1805. He describes it 1813/1814, too late for Constantine Samuel Raffinesque (1783-1840) to have read it. Usually Raffinesque quotes Pursh if the latter saw a specific plant before he did, but he saw this Drosera around 1803/1804 also in New Jersey and described it in 1808, well before Pursh. Hence its find is attributed to him.

This is from my own specimen. The leaves of this sundew unroll in nice-looking spirals. Gnats and midges are its main preys.

This carnivorous plant was growing in the Stanley Rehder Carnivorous Plant garden in Wilmington, NC. This plant is an insect predator, and you can see some of its prey in this image.

Threads to Condemn
Description: The Drosera filiformis is a perennial (insectivore) carnivore plant belonging in the class Magnoliopsida, order Caryophyllales, suborder Polygonineae and family Droseraceae.
Once the seeds germinate, tiny threads of curved leaves begin to form. The curves are in spiral and proceeds to slowly uncurl as the plant grows. Many leaves are born and they grow tall compared to other Drosera species. Once the leaves are fully grown, they take an erect or semi-erect appearance. Their natural distribution areas extend from the East coast of North America from the Southwest of New Scotland, to the North, through New England to Florida and Louisiana, to the South. They grow in marshy places with poorly-mineralized soil where umidity is constant and sunlight abundant. There are many variations and hybrids, and all were introduced in other places. All of them should be cultivated equally; abundant watering with chlorine-free water and abundant sunlight with a substract consisting of poor-quality soil that can retain water, preferrably Sphagnum sp. moss, live or dehydrated. Rich or semi-rich soil burns the roots, and so does water with chlorine.
They do require winter protection if grown in cold weathers as the plant is sensitive to frost, but the seeds need colder temperatures to germinate. To germinate the seeds, they should be scattered onto damp and cold stratification. Sphagnum sp. moss is exceptional at this. The seeds should never be buried as they need the direct contact with sunlight to germinate; this means you should spray water instead of dropping a heavy amount of water onto the substract, as the heavy impact may bury the seeds.
The plant can catch prey on its own, with no need of human interference and they can survive with water alone.
Drosera filiformis needs a dormancy period. When this dormancy happens, the leaves of the plant will completely wither and die and a hibernacula (a small, brown, dormant bud just at or below the soil level) is produced. Resistance to cold is drastically increased during this stage, which remains for several months. When the temperature grows the plant will re-emerge from the hibernacula and proceed to grow.
The leaves are covered with tiny structures that ooze a droplet of mucilage. This mucilage is extremely sticky attractive to insects, which get digested by the plant when stuck through the production of digestive enzymes. The flowers are of a pinkish coloring.
The propagation is done through seeds or through leaves in a process known as "leaf-cutting".

When I recently checked the front yard bog garden, I noticed that there were some natural, self-sown baby plants.
Last fall, I trimmed the old Pitcher Plant pitchers and scattered the seeds around, hoping they would germinate and thrive. Now is the time when they are at their most vulnerable. I'll have to keep them watered, and maybe they will mature into adult plants.

Thread-leaved Sundew (Drosera filiformis)
Rural Habersham Co., GA (Carnivorous Plant Garden)
First wave of flowering of my front yard bog garden. The Sarracenia flava (Yellow Pitcher Plant) is usually the earliest to bloom. Great, except the flowers smell strong like cat urine!
The NC Coastal Land Trust hosted its Flytrap Frolic in the Stanley Rehdar Carnivorous Plant garden. This is the first time I have seen the Thread Leaf Sundew (Drosera filiformis Raf.) in the garden. This species is supposed to be expatriated from New Hanover County (plants.usda.gov/core/profile?symbol=DRFI), so it was a special treat to see it. Perhaps it was planted from a cultivar? Regardless, its a beautiful plant.
These appear to be listed as "Significantly Rare" in North Carolina (www.ncwildflower.org/plant_galleries/carnivorous).
Drosera x 'California Sunset' is a carnivorous sundew that catches insects on its dewy leaves to compensate for the nutrient poor soils where it grows. It is a hybrid of Drosera filiformis and the similarly filiform Drosera tracyi made by Joseph A. Mazrimas in 1980.

Drosera filiformis is native to eastern seaboard of the USA and grows reasonably well in other temperate parts of the world; including here. I hoped to capture the wonderful architecture of an uncurling leaf in this photo. The field of view is about 6 mm across.

The Threadleaf Sundew - Drosera filiformis ‘California Sunset’ emerging from hibernation. This is cross between Drosera filiformis var. filiformis and Drosera filiformis var. tracyi originated by Joseph A. Mazrimas, Like all Drosera, it is a carnivorous plant that catches small insects like gnats on its sticky tentacles and digests them for nutrients that are lacking in the nutrient poor soils where it grows.
