Ash-gray sedge due to its vast range and wide ecological confinement is a variable species. Plants from North America have, on average, wider leaves than plants from other parts of the Northern Hemisphere. Plants from the Southern Hemisphere, in comparison with plants of the Northern Hemisphere, have a thicker stem, broader leaves and sacs, they can be considered as an independent variety.
Geographic distribution. Panboreal bipolar species, the range of which covers the tundra, forest and partly steppe zones of Eurasia and North America. Fragments of the range of the species are known in the Himalayas, on the island of Sicily, in the Andes (in the southern regions), the Falkland Islands, New Guinea, Southeast Australia, and Tasmania. In the Arctic regions of Eastern Siberia, there are few finds of the species, in Greenland it is found south of 70 ° C. w.
Morphological description. Soddy perennial with erect or arched ascending extravaginal shoots. Young roots are whitish, old light brown, up to 40 cm long and 0.6-0.8 mm in diameter. In addition to relatively thick roots, thin roots are formed, they are branched, 6-13 cm long and 0.2-0.35. mm in diameter. Stems 15-60 cm tall, 1-1.2 mm in diameter, acute trihedral, covered, like leaves, with papillae or tiny bristles. The lower scaly leaves are brown or dark brown, sometimes with a very faint purple hue, usually with noticeable dark veins.
The inflorescence is 2-7 (9) cm in height from 4-7 (10) gynecadric spikelets, the upper of which are compactly brought together and the lower ones are apart, which makes the top of the spikelet hardly or hardly reaches the base of the superior spikelet. Spikelets oblong, multi-flowered. Stigma 2.
Ontogenesis, the rhythm of seasonal vegetation, methods of reproduction and distribution. Seedlings and annual plants of ash-ash sedge consist of 1 shoot connected to the fruit. Juvenile plants are 2–3 years old. Immature and adult virginal individuals are characterized by: the beginning of tillering, i.e., the development of lateral shoots of the first order from the kidneys of the maternal axis, and in the fourth and subsequent years of life - the formation of lateral shoots of higher orders.
Flowering in different years lasts from mid-May to early June. The fruits ripen by early July. They can spread by water, as they float in it.
Ecology and Phytocenology. Ash-gray sedge grows in conditions of uniform crisis-free wet-meadow and bog-meadow moistening, on gleyed or peaty soils, poorly aerated, not rich in nutrients. This species is an indicator of medium-acid soils with a pH of 4.5-5.5, acidophilus. It belongs to the group of half-light plants, but can grow in full light, tolerates some shading. Hemicryptophyte.
It grows on grass sedge, less often mossy swamps, marshy meadows, in shrubs, damp forests, on littoral reservoirs, usually as an admixture, less often as a subdominant.
Counseling Relations. Well, eaten by a reindeer. Affects smut.

Gray sedge, or gray sedge, club sedge (Carex grayi)
Perennial herb, species of the genus Sedge (Carex) of the Sedge family (Cyperaceae).
Perennial. Early growing sedge.
It differs in very original fruits, for which it received the name "sedge of the morning star." The large seed sacs of this sedge form an almost spherical star.
Light green, almost lettuce leaves form a hill-shaped, slowly spreading hummock, up to 90 cm high. It forms a dense strong bush that does not require a garter.
At the end of June, flower-bearing stems appear, at the end of which club-shaped seed heads of light green color, with a diameter of 2-4 cm, are formed, which do not lose their attractiveness all summer and autumn.
The root system of the plant is a rhizome with short internodes and quite powerful, nourishing roots extending into the soil to a depth of more than 20 cm.
At the beginning of summer, the balls are green, but gradually their color changes and by autumn it becomes dark brown. The tips of the leaves also darken. All this very decorates the plant.
Quite large seeds ripen inside the fruit tree by autumn.
It prefers fertile moist loam; the soil reaction is closer to neutral.
Withstands temporary flooding. Soil prefers humus fertile.
The plant is winter-hardy, does not require shelter for the winter.
It is used for single plantings, creating borders and mixborders, as an accent plant in natural style flower beds, in large numbers - along the banks of water bodies.
Landing: Propagated by division of the rhizome in the spring or seeds.
Seeds germinate easily, they are sown under snow in the ground or indoors in March.
Sow on the surface of the substrate, sprinkle 1-2 mm and moisten. Place the container in a bright place, this will accelerate the germination of seeds. Keep the temperature at 15-20C.
Maintain a temperature of 15 degrees until the seedlings are strong. As soon as the plants grow, they should be transplanted into pots or in a permanent place.
Sowing in soil is possible, starting in April. Prepare the soil well before sowing. Form grooves with a depth of 2-3 cm, sow in increments of 20-30 cm. Germination time depends on soil temperature and weather conditions, and can take from 7 to 20 days.
In the second year of life, seedlings bloom.
