Another name for the sundew is drosera. This plant belongs to insectivores, grows in natural conditions around the globe. Most of more than a hundred species are concentrated in New Zealand and Australia. Large-leaved sundew is common in northern latitudes, well adapted to temperate climates and marshlands. This variety received a beautiful and poetic name from the English people, who called the plant “sunny dew”.
In the wild, sundew propagation is carried out by seeds, which are sown and germinated themselves. After the grain has touched the soil, sprouts appear in a year..
Many representatives of this species reproduce through self-pollination, others do it with the help of insects. Plants catch flies not with flowers, but with sticky leaves, and therefore, during pollination, the flower is not terrible for them. The stem with a bud is significantly higher than the dangerous leafy plates.

The species is also common in New Zealand. Many populations of sundew in this region are characterized by year-round flowering: these are numerous white buds. Some species hibernate in winter and wake up in spring. This variety is fundamentally different from others. The leaves are outwardly forked narrow, they grow on the branches.
This sundew is the largest among its fellows: the flower grows upwards by 65 cm.
Dewdrop of Alicia
The homeland of Alicia’s sundew is South Africa, where the plant feels great in the subtropics. The leaves of this sundew, like those of other species, are covered with villi, the tops of which are smeared with a sticky liquid. Oval plates on the surface have special hairs that react very clearly to insect touch. After folding the sheet, the victim is in its center, like the filling of a roll. The plant envelops the insect and the process of digestion begins. When it is finished, the sheet returns to its original position. Flowering is carried out by small pink flowers located in small inflorescences.
The flower owes its name to the scientist Johannes Burman, since it was he who first described it in a work entitled “On the flora of Ceylon”. The homeland of the variety is Southeast Asia and Australia. The species is adapted for living in the subtropics.
A distinctive feature of the Burman sundew relative to its other relatives is the rapid swallowing and processing of prey.
It only takes a couple of seconds for the piece of paper to wrap itself around the victim, although other species do the same for a few minutes.
Long leafy plates of the flower grow from the root, and the shoots reach 9-11 cm. Flowering occurs with white flowers, decorated in racemose inflorescences. Due to the small size of the plant, up to three buds are formed on each branch. Flowers can self-pollinate, reproduction occurs by seeds.

Young shoots emerge from the peduncle where it comes into contact with the soil, they grow very quickly. Sundew propagation is carried out by seeds, and sometimes this process is similar to the growth of strawberries – after flowering, it forms a mustache. This species, like related varieties, swallows insects: the leaf rolls up in 19 minutes..
Rosyanka Glanduliger: petiolate and lemon
This type of sundew is quite original. This concerns the process of dealing with the victim. A special mechanism throws up the prey, and it directly appears in the center of the leaf. The shoots are engaged in such a kind of throwing, for which this process is based on a change in fluid pressure. The speed is approximately 15 cm per second. This distinctive feature has been described by scientists quite recently, and the process has not yet been fully studied. Each branch can make only one toss, after which it dies. A new shoot is formed in the same place.
The petiolate species of sundew is native to New Guinea and Australia. Deciduous plates are located at the roots, they are long and narrow, reaching a height of 16 cm. The plant’s predatory leaves do not differ in large size. The appearance of a flower depends on the climate where it lives. As a rule, this is heat and temperatures up to 41 ° C, as well as a low level of humidity. Flowers have a white tint.
Lemon sundew in a natural environment lives in Australia, grows excellently on the sandy shores of reservoirs. The leaves are oval in shape, flat, and there is a notch at the top. Due to this appearance, the plant received another name – heart-shaped or toothed. This species requires special care due to the too thin leaves.
