Valerian (lat.Valeriana officinalis), or valerian medicinal, or cat herb - a species of the genus Valerian of the Honeysuckle family. The homeland of the plant is the Mediterranean. It is distributed in the subtropical and temperate zones. Valerian grows among thickets of bushes, in swampy and low-lying meadows, swamps, glades and forest edges. Valerian medicinal and its healing properties have been known for a long time: Avicenna, Pliny and Dioscorides believed that this plant was able to strengthen and calm the brain and control a person's thoughts.
In the Middle Ages, valerian was used as an aromatic and sedative agent. The plant got into the pharmacopoeias of European countries only in the 18th century, at the same time the industrial cultivation of medicinal valerian began.
There are different opinions about the origin of the name of this plant. Some, for example, argue that Valerian was so named after the Roman emperor, others - that in honor of the physician Pliny Valerian. Translated from Latin, "valerian" means "to be healthy."

Planting and caring for valerian

  • Bloom: from the second season, it lasts almost all summer - from May to August.
  • Landing: sowing seeds in open ground - in early spring, planting valerian stolons in the ground - in October.
  • Lighting: bright sunlight.
  • The soil: well drained, moderately dry.
  • Watering: crops are watered quite often, and at first you need to pour water through a fine sieve so as not to wash the seeds out of the soil. As soon as shoots appear, you can water less often.
  • Top dressing: at the stage of development in seedlings of the first pair of leaves, and then at the stage of formation of the fifth leaf, a solution of bird droppings is introduced into the soil.
  • Reproduction: seeds, dividing a tuber or rhizome.
  • Pests: sandy slugs, winter moths, meadow moths, valerian aphids and beet bugs.
  • Diseases: root rot, rust, powdery mildew, fusarium.
  • Properties: long known medicinal plant with healing properties.

Botanical description

Valerian is a herbaceous perennial, reaching a height of 120 to 180 cm. Valerian's rhizome is thick and short, with a loose core, sometimes hollow with transverse septa. Stolons and thin adventitious roots up to 12 cm long, smooth and brittle, extend from the rhizome. Valerian rhizome has a strong aroma.

The stem of the plant is fistulous, erect, furrowed and branching in the upper part. The middle and lower leaves are long-petiolate, the upper ones are sessile, pinnately dissected, opposite, alternate or collected in whorls of 3-4 pieces. White, small fragrant bisexual flowers up to 4 mm in diameter are collected in large axillary and apical scutes or panicles. From the second year of life, the flowering of Valerian officinalis lasts almost all summer. Fruits - achenes ripening in late summer or early autumn.

Growing valerian

Landing

Valerian grows well both in the sun and in partial shade, and even in the shade. Sowing seeds is best done in early spring, but then the area for valerian needs to be prepared in the fall: dig it up with compost (humus) and full mineral fertilizer to a depth of 25-30 cm, and in spring, as soon as the top layer of soil dries out, the surface is only harrowed with a rake. However, valerian seeds lose their germination very quickly, so experienced gardeners prefer to sow in the summer, immediately after collecting the seeds, after digging up the soil with organic matter at the rate of 5-7 kg of humus or compost for each m² of the plot.

Valerian seeds are sown into shallow grooves without sealing, and sprinkled on top with a layer of humus with sand or sifted peat 1 cm thick. The row spacing is 8-10 cm. Until shoots appear, the soil on the site should be slightly moist all the time.

For those who already have valerian growing, it is more convenient to propagate it with stolons: in the fall, in October, valerian bushes are dug up, the tops are cut on them, and the stolons are separated from the rhizome - underground shoots, which are the planting material. From one bush, you can get from 5 to 8 stolons with buds ready for propagation. Valerian rhizome is useful for medical needs, and stolons are immediately planted in a previously prepared bed at a distance of 15-20 cm from each other. After planting, the site is watered. The survival rate of valerian stolons is very high.

Care rules

At first, the crops are watered carefully, through a strainer, so as not to wash the seeds out of the soil. After the emergence of seedlings, watering is carried out less often. At the stage of development, at the seedlings of two true leaves, the rows are thinned out with a step of 3-4 cm, after which the seedlings are fed with a solution of bird droppings (1:12), and the second feeding is carried out when the valerian develops five leaves.

Valerian, sown in spring, can already give its first harvest in autumn. Every second plant is dug up, and the rest are fed for the winter with Nitroammofoskoy at the rate of 50 g of fertilizer for each m² of the plot. For the winter, the bed with valerian is covered with small branches, and a layer of dry stems or straw 5-6 cm thick is thrown on top of them. If a thaw begins in the middle of winter, make windows in the straw so that the valerian does not wither.

In the second year of life, valerian will bloom, but as soon as the seeds begin to ripen, the peduncles need to be cut off, and the valerian should be fed with a solution of bird droppings. If you need seed, keep cut valerian stalks under a canopy until the seeds are fully ripe. In the fall, valerian rhizomes are dug up.

Collection of valerian and storage at home

How to collect

Rhizomes are harvested in October, when the stems of the plant turn brown and dry. Only correct preparation of valerian fully retains its healing properties. The roots must be dug up, cleaned from the ground, freed from the remains of ground organs, quickly but thoroughly rinsed under running cold water and dried in the fresh air for two days.

How to dry

The valerian roots are then placed in a warm room on a wire mesh and dried for two weeks, turning over from time to time. You can dry the rhizomes in a dryer or oven at 35-40 ºC - this will save you a lot of time. During drying, the rhizomes acquire a brown color and a strong characteristic aroma. From one kilogram of fresh roots, after drying, about 200 g of dry ones are obtained.

For storage of finished raw materials, tight-fitting containers are used, otherwise the essential oil will evaporate. Valerian root has a shelf life of 3 years.

Types of valerian

Valerian officinalis is the most popular, but far from the only species of the genus. However, the rest of the valerian species introduced into the culture are grown as ornamental plants. The most attractive ones are:

Valeriana Altai (Valeriana altaica)

Or (Valeriana turczaninovii = Valeriana heterophylla = Valeriana reverdattoana) - a plant native to Northern Mongolia and Siberia with an elongated rhizome and straight, bare or almost bare stems. The basal leaves of the Altai valerian are whole or with two lateral segments, and the stem leaves are lyre-pinnate-dissected. The inflorescence is capitate, sometimes with additional small heads. The flowers are narrow-funnel-shaped, light pink. The fruits are glabrous, purple in color.

Valeriana petrophila

from the same places as Altai Valerian. She has a shortened rhizome with cord-like lobes and stolons with a bunch of leaves at the ends, ascending or curved stems from 5 to 20 cm long, one third of which cover the vaginal leaves. The lower long-petiolate leaves are rolled into a raised rosette, and the sessile leaves of the upper pair can be whole or with two or three pairs of small lateral segments. Dense racemose, almost capitate inflorescence of pink flowers grows and becomes friable during fruiting.

Valeriana supina

- a plant from the eastern regions of the Alps. It has rounded ovate leaves, collected in a basal rosette. This species forms light green pads with a height of 2 to 7 cm. Valerian blooms in bed with small pink flowers, collected in dense inflorescences up to 3 cm in diameter. This species is used as a ground cover plant in rock gardens. Valerian recumbent forms many underground stolons and is capable of capturing large territories.

Rock Valeriana (Valeriana saxicola)

occurs at an altitude of 1800 to 2500 m above sea level in the mountains of the Caucasus and Turkey. This is a perennial no more than 15 cm high, forming small bushes. The few stem leaves of this species are narrow, basal - oval-oblong, sometimes pointed, up to 2 cm long. Pink flowers form a compact racemose inflorescence.

In addition to those described, in the culture there are such types of valerian as capitate, mountain, lipoliferous and three-winged, but they do not have high decorative qualities.
