Round-leaved Sundew is a perennial insectivorous plant. It has one stem, without leaves, which can reach 10-25 cm in height. In rare cases, such stems are 2-3.
The leaves of round-leaved Sundew are arranged on the soil. They have long petioles and form a root rosette. The leaves are round, up to 2 cm in diameter. The upper and lower sides of the leaves are covered with hard, red hairs on the long stems, the hairs tend to reach 4-5 mm. The hairs contain glands that secrete a sticky solution that accumulates on the surface of the plant as shiny droplets. Hairs are very sensitive to irritation. As soon as the insect touches the leaf of the round-leaved Sundew , the hairs bend to grab the victim.
The leaves of insectivores are interesting - the shape of the leaf is like a head, the upper part is covered with hairs-glands, and on each of them there is a drip that attracts a potential victim. These drops are especially brilliant in the early morning hours and in the evening sun, hence its name "Sundew".
Dew, the droplets secreted by the glands, contains a sugar solution to attract insects. The attractive droplet "dew" is a sticky slime that prevents the victim from swallowing. The leaf of the plant is sensitive to the touch, it remains for the insect to touch it and the hairs on the leaf bend to the victim, "generously" covering the victim with the sticky solution. In addition, with the help of hairs, the victim is moved to the center of the leaf - there is a digestive fringe. Gradually, the round-leaved Sundew leaf closes and becomes a conditional "stomach", where the processing of the insect takes place. Once the insect's soft tissue has been processed, only the insect's exoskeleton remains and the leaf has returned to its normal, upright position.
Round-leaved Sundew flowers are white and small, arranged in long curls. The plant blooms in June-August, the fruits ripen closer to the end of summer-beginning of autumn. The fruit is an elongated, oval capsule. The seeds are small, spindle-shaped and light brown in color.

In cases where the plant is pulled out with the whole root, then the root should be cut off, but the grass should be rinsed from debris and moss.
