Sundews are “flypaper” plants that trap prey in sticky hairs on their leaves. They make up one of the largest groups of carnivorous plants. Long tentacles protrude from their leaves, each with a sticky gland at the tip. These droplets look like dew glistening in the sun, thus their name.
Considering enough water was provided, this generally means that the light intensity (and heat, as well) was too much for the sundew to handle. Also, the leaves may lose all their dew and the leaves will appear "sunburnt" (an unhealthy pink/red coloration).
Why are my sundew leaves turning black? Sundew leaves turn black if they've been moved from a location to another. In this case, it's a stress response. This also happens if they have been put in direct sunlight for too long.

Pygmy sundews reproduce asexually using specialized scale-like leaves called gemmae. Tuberous sundews can produce offsets from their corms. In culture, sundews can often be propagated through leaf, crown, or root cuttings, as well as through seeds.
Wildflowers of the Adirondacks: Roundleaf Sundew appears to have limited edible or medicinal uses. Roundleaf Sundew (Drosera rotundifolia) on Barnum Bog (20 July 2019). Roundleaf Sundew appears to have limited edible or medicinal use in the US. Native American groups reportedly made little use of this plant.
Sundew has a small and wiry shape and a face that is similar to Belladonna's. She has dark forest-green scales that are flecked with gold, and she also has golden scales along the edges of her wings, talons, and across her snout.
The "dew" of the sundew is actually mucilage. Mucilage is a thick, sticky substance secreted by some plants. The runny, sticky "juice" of the aloe vera plant, for instance, is mucilage.

Sundews are “flypaper” plants that trap prey in sticky hairs on their leaves. They make up one of the largest groups of carnivorous plants. Long tentacles protrude from their leaves, each with a sticky gland at the tip. These droplets look like dew glistening in the sun, thus their name.
Once an insect becomes stuck, nearby tentacles coil around the insect and smother it. Sundews can reach a height of up to 10 inches (25 centimeters).
These plants feed on insects. Mosquitoes are abundant in the sundews’ preferred habitat and can make up a significant portion of their diet in these locations. Sundews can kill a trapped insect in about 15 minutes, but may digest it over a few weeks.
Two species ( D. katangensis and D. insolita) native to the Democratic Republic of the Congo are listed as critically endangered on the IUCN Red List of Threatened Species. Sticky gland-tipped hairs of the roundleaf sundew ( Drosera rotundifolia ), which attract and digest insects.
Sundews are widely distributed in tropical and temperate regions, especially in Australia, and are common in bogs and fens with sandy acidic soil.
The most common North American and west European sundew, the roundleaf sundew ( Drosera rotundifolia ), has small white or pinkish flowers 1.25 cm (0.5 inch) across or less and bears round flat leaves with purplish hairs on a long fuzzy stalk. The Cape sundew ( D. capensis ), native to the Cape region of South Africa, features long narrow leaves with red-tipped glands and is commonly sold as a novelty plant. Two species ( D. katangensis and D. insolita) native to the Democratic Republic of the Congo are listed as critically endangered on the IUCN Red List of Threatened Species.

The upper surface is covered with flexible gland-tipped trichomes (plant hairs) that exude a sticky substance to attract and entrap insects and other small prey. Trapped prey are engulfed in a web of the sticky glands, colloquially known as tentacles, and digested by enzymes.
Drosera species vary from several centimetres to a metre (3.3 feet) or more in height. The smallest species often are hidden among the mosses in a sphagnum bog. The sundews of the Northern Hemisphere usually produce 1 to 20 erect flowers on a single flower….
Drosera filiformis var. filiformis in a peat bog in New Jersey. The range of the sundew genus stretches from Alaska in the north to New Zealand in the south. The centers of diversity are Australia, with roughly 50% of all known species, and South America and southern Africa, each with more than 20 species.
The genus can be divided into several habits, or growth forms: 1 Temperate sundews: These species form a tight cluster of unfurled leaves called a hibernaculum in a winter dormancy period (= Hemicryptophyte ). All of the North American and European species belong to this group. Drosera arcturi from Australia (including Tasmania) and New Zealand is another temperate species that dies back to a horn-shaped hibernaculum. 2 Subtropical sundews: These species maintain vegetative growth year-round under uniform or nearly uniform climatic conditions. 3 Pygmy sundews: A group of roughly 40 Australian species, they are distinguished by miniature growth, the formation of gemmae for asexual reproduction, and dense formation of hairs in the crown center. These hairs serve to protect the plants from Australia's intense summer sun. Pygmy sundews form the subgenus Bryastrum. 4 Tuberous sundews: These nearly 50 Australian species form an underground tuber to survive the extremely dry summers of their habitat, re-emerging in the autumn. These so-called tuberous sundews can be further divided into two groups, those that form rosettes and those that form climbing or scrambling stems. Tuberous sundews comprise the subgenus Ergaleium.
The root systems of most Drosera are often only weakly developed. Serving mainly to absorb water and to anchor the plant to the ground, the roots are relatively useless for nutrient uptake. A few South African species use their roots for water and food storage. Some species have wiry root systems that remain during frosts if the stem dies. Some species, such as D. adelae and D. hamiltonii, use their roots for asexual propagation, by sprouting plantlets along their length. Some Australian species form underground corms for this purpose, which also serve to allow the plants to survive dry summers. The roots of pygmy sundews are often extremely long in proportion to their size, with a 1-cm (0.4-in) plant extending roots over 15 cm (5.9 in) beneath the soil surface. Some pygmy sundews, such as D. lasiantha and D. scorpioides, also form adventitious roots as supports. D. intermedia and D. rotundifolia have been reported to form arbuscular mycorrhizae, which penetrate the plant's tissues.
Sundews were used as medicinal herbs as early as the 12th century, when an Italian doctor from the School of Salerno, Matthaeus Platearius, described the plant as an herbal remedy for coughs under the name herba sole. It has been used commonly in cough preparations in Germany and elsewhere in Europe. Sundew tea was especially recommended by herbalists for dry coughs, bronchitis, whooping cough, asthma and "bronchial cramps". A modern study has shown that Drosera exhibits antitussive properties.
Sundews are perennial (or rarely annual) herbaceous plants, forming prostrate or upright rosettes between 1 and 100 cm (0.39 and 39.37 in) in height, depending on the species.
Filicirna Raf. Rossolis Adans . Drosera , which is commonly known as the sundews, is one of the largest genera of carnivorous plants, with at least 194 species. These members of the family Droseraceae lure, capture, and digest insects using stalked mucilaginous glands covering their leaf surfaces.
These members of the family Droseraceae lure, capture, and digest insects using stalked mucilaginous glands covering their leaf surfaces. The insects are used to supplement the poor mineral nutrition of the soil in which the plants grow.
All Sundews capture prey by using glistening drops of “dew” for which the plant derives its common name. The shape, size, color, and mobility of the leaves vary across varieties yet each is densely covered with small tentacle-like hairs with singular drops of dew at their tips.
In reality, the drops of “dew” are actually sweet smelling and sticky drops of mucilage that the plant secretes in order to attract its prey. The bug lands on the plant thinking that it has found a sweet meal, but it becomes stuck in the goo and becomes a meal itself!
