Plant characteristics and classification of cleavers
Origin and occurrence of cleavers
Cleavers is a plant of Eurasian origin, which originally originated in Europe and western Asia. It is common in almost all of Europe. It also occurs in the North Caucasus, in the coastal areas of Asia Minor and the Mediterranean, as well as in Northwest Africa (Atlas Mountains). In North America, it was introduced. Due to its high ecological tolerance, it quickly populates new areas. As a typical neophyte, this species of cleavers is today widespread almost all over the world. It can be found in both cold Siberian and warm Australia.
In Central Europe, the Cleavers is found wild on and near agricultural land, in riparian forests, nutrient-rich wasteland, fallow land and at forest edges. The plant is considered a typical nitrogen indicator and therefore prefers sites with a high nutrient supply. In the mountains, the species can be found up to 1,500 meters (4,900 feet).
Plant order of cleavers
Cleavers (Galium aparine) belongs to the family of the bedstraw plants. In the narrower classification, the species is classified in the genus Galium, which is relatively rich in species with more than 600 species. Known relatives of cleavers are woodruff (Galium odoratum), the hedge bedstraw (Galium mollugo) as well as the lady’s bedstraw (Galium verum).
Characteristics of cleavers
Cleavers are annual and herbaceous plants, which can reach stature heights between 40 and 160 cm (15 and 63 in). The shoots of cleavers grow up or climb and attach themselves to other plants. In the soil cleavers forms rather thin and brownish roots, which usually grow laterally. The roots can be up to 40 cm (15 in) long.
The leaves of cleavers are lanceolate and with small glandular hairs. The leaves are six to nine in whorls. The leaf width is rarely 1 cm (0.4 in), the length up to 6 cm (2.4 in). Its stem is usually edged and square shaped with a striking number of small bristles.
At flowering time, which usually lasts between July and September, cleavers forms white flowers. Up to five hermaphrodite flowers are grouped in so-called cyme, which also grow from the whorl. The blossoms are quite small with a width of 1.5 to 2 mm (0.06 to 0.08 in). Each flower has four stamens, four petals and a barely recognizable calyx.
The fruits are 3 to 5 mm (0.12 to 0.2 in) long andalways larger than the petal. The olive or purple fruits are densely covered with bristly hooks. The two sub-fruits are schizocarps, each contain one seed and. Fruit ripeness begins in May and lasts until October. After the ripeness, the plant dies.
Cleavers – cultivation and care
Cleavers is often seen as a weed and hence rarely cultivated. Occasionally, however, the plant is cultivated in herb gardens or medicinal gardens due to its medicinal properties. The cultivation itself is not very difficult.
A good location for cleavers is a rather sunny and sheltered location. Half shady locations are also tolerated, although the growth of cleavers suffers significantly. Preference is given to more clayey, slightly moist and calcareous mixed soil with medium to high nutrient supply, especially nitrogen. Most garden soil and herb soil are suitable for the cultivation of the herb. However, sandy or heavily overfertilized soils can be a problem.
The months of March to April are the optimal sowing time. Since it is a cold germ, it is also possible to sow late in the autumn, which should happen from about mid-October. The seeds can be put directly into the field or in a large pot. The sowing depth should not exceed 1 cm (0.4 in). Planting distance should be at least 25 cm (10 in) in all directions.
In most cases no additional nutrient supply is necessary. Only in known nutrient-poor soils or pot plants, an additional supply of fertilizers is necessary. For this purpose, normal, nitrogen-stressed fertilizer or compost is recommended.
Cleavers is a rather moisture-loving weed, similar to woodruff. A continuous supply of water is therefore needed, otherwise diseases can quickly occur. It is important to keep the soil always slightly moist, whereby waterlogging should be avoided at all costs. Short dry periods of three to five days are generally tolerated without any problems. If the plant is watered daily, only the soil should be watered (do not dash the plant).
Diseases and pests
Like most cleaver species, cleavers is a rather robust plant. In cultivation or care errors, e.g. too small planting distances, oversupply with nutrients or too moist soil, it can come to infestation with powdery and downy mildew.
Cleavers are annual plants. These die off after fruit ripeness, which means that no wintering measures are necessary.
Use of Cleavers
