Why is it called that?

There is such a grass - coltsfoot. But few people know why it is called that. Apparently, the fact is that if you examine the leaf of this plant from the “front and back,” you can see that one side of the leaf feels warm, affectionate, and fluffy, like a mother. And the other, lower side, if you touch it, is cold, hard and slippery. This is the stepmother.

Coltsfoot (lat. Tussilágo) is a monotypic genus of perennial herbaceous plants of the Asteraceae family. The only species is the common coltsfoot (lat. Tussilágofárfara). It blooms in early spring, before the leaves bloom. Since ancient times it has been used as a medicinal plant.

Biological description The rhizome is long, branched, creeping. Two types of shoots develop from the buds on the rhizome: flowering and vegetative. In early spring, erect, low flowering shoots, covered with ovate-lanceolate, often brownish, scale-like leaves, begin to develop. On each of the shoots a single, drooping head develops before and after flowering, consisting of a cylindrical single-row spathe, a bare flat receptacle and bright yellow flowers of two types. Numerous outer (marginal) flowers are female, ligulate (the clearly expressed ligule of the marginal flowers is a diagnostic feature by which the coltsfoot differs from plants of the genus Butterbur, in which this ligule is not clearly expressed, the corollas are almost thread-like, and the number of marginal flowers is relatively small ), fertile. The flowers, which are located in the middle of the inflorescence, are bisexual, tubular, sterile. The fruit is a cylindrical achene, with a pappus (tuft) of soft hairs. After the fruits ripen, the flowering shoots die off. Some time after the start of flowering, vegetative shoots begin to develop, which bear several relatively large rounded-heart-shaped, slightly angular (angular-unevenly jagged), white-tomentose below, bare leaves with long petioles above.

It is usually found in areas free of turf - the banks of reservoirs, on the slopes of ravines and landslides, often in areas subject to anthropogenic impact - fields, wastelands, landfills. Prefers clay soils, but is also found on other types of soils, including sandy and pebble river shallows. The usual flowering time in the European part of Russia is in April.

Medicinal properties

Back in ancient Greece and Ancient Rome, coltsfoot was known as a medicinal herb with a fairly wide range of uses. Without going into tedious details of its chemical composition, we can highlight several of its main medicinal (pharmacological) properties: enveloping; antispasmodic; emollient; expectorant; anti-inflammatory; antiseptic. active substances have a complex effect on inflammatory processes. Coltsfoot is a traditional remedy for coughs, especially whooping cough, and also for mucous phlegm. Drinking tea from it can ease coughing and make viscous bronchial mucus more liquid. Used for chronic bronchitis, laryngitis, bronchopneumonia, bronchiectasis and bronchial asthma

“Coniferous plants” - Spruce bark is eaten by spruce beetles and bark beetles. Woodpeckers love to pull bark beetles out of spruce trunks. Spruce provides great shade. Crossbills build nests on spruce trees and hatch chicks. Christmas trees for Christmas tree markets are specially grown in nurseries. Squirrels pull seeds out of spruce cones. Every 5-7 years the prickly needles fall off.

"Flower. Miraculous transformation” - The time will come, the seeds will fall into the ground and give life to new plants. In the sun the flower blooms. The bee's body is covered with flower pollen. Other fruits have seeds inside, like an apple. The sprout becomes bigger and bigger, stronger and stronger. A small seed fell to the ground. Fruits come with pulp, such as cherries, and there are fruits without pulp, for example, nuts.

Sometimes you are surprised how many interesting things we don’t know. We can’t remember the name of this or that flower, tree or shrub. We don’t know what plants are found in our village and how they can be used.

“Fairy tales can be told about every blade of grass, about every inconspicuous little buttercup or spikelet. And the life of even the simplest and most modest flower is often more interesting than the most magical fairy tales.” According to K. Paustovsky
