Botanical description of rose hips

Cinnamon rose hips are a shrub up to 2.5-3 m high. The branches are thin and shiny. The color is brownish-brown or brownish-red. The spines are few, small, curved downwards, usually located in twos at the base of the leaves. There are spines and bristles.

Rosehip leaves are unpaired, consisting of 7-9 lateral leaflets. The leaves are thin, oblong, narrowed towards the base, twisted at the top, have denticles along the edge, covered with bluish-green hairs, the network of veins is very protruding.

Rosehip flowers are arranged singly or collected 2-3 in a few umbrella-shaped inflorescences. The color is pink, pale or dark red. Diameter 3-5, up to 6, cm. The aroma of rosehip is delicate and pleasant.

Rosehips are small (up to 1.5 cm in diameter), round or oblong, smooth, glabrous, fleshy, and contain numerous seeds (fruit-nuts). The sepals are retained at the top. Color orange, orange-red or red. The inner walls of the fruit are covered with many very sharp bristly hairs.

Rose hips bloom in May-July, the fruits ripen in August-September and remain on the branches until winter.

Rose hips propagate by seeds, suckers and green cuttings. It begins to bear fruit at 2-3 years of age, reaching a maximum at 10-12 years.

Advantages of cultivated varieties of rose hips

Initially, wild rose, moving from the wild to a garden plot, did not have such a choice of varieties. Now the species and varietal diversity is so great that it is sometimes difficult to make a choice. Cultivated rose hips have a number of advantages over their wild counterparts:

  • larger fruits (berries) have a lot of healing properties and are used in cooking and medicine;
  • brightly colored and large berries are also a decorative element, decorating autumn bushes and enlivening the landscape;
  • bushes are decorative in any season - in spring and summer they diversify the landscape with bright greenery, diluted with the lights of flowers, in autumn flowers replace bright fruits, and in winter the lace of branches looks organically against the background of white snow;
  • caring for the crop is simple and does not require much effort;
  • the root system, powerful and strong, helps, if necessary, prevent erosion of the soil, and lush bushes will hide the flaws of the site;
  • a large selection of varieties and varieties with different flower colors and bush sizes.

Habitat

Cinnamon rose hips are widespread in most of the CIS. It can be found in the European part - with the exception of the Baltic countries and the Black Sea region of Russia, in Western Siberia - with the exception of the Far North, in Eastern Siberia - in the Angara-Sayan region, in the Yenisei region the plant is rare, as well as in Central Asia.

Rose hips grow in sparse mixed and deciduous forests, among shrubs, along the edges, clearings, meadows, along ravines and mountain gorges, on rocky slopes, preferring the banks of rivers, lakes and other bodies of water. There are both single plants and groups (thickets).

Planting rose hips in open ground

What time to plant

It has been noticed that if rosehip is planted in the fall (October–November), it will take root much better than when planted in spring. But if there is such a need, then the plant can be planted in the spring. The best place for planting will be a sunny area located on a hill. When choosing a place for planting, you should remember that the root system of this crop goes into the deep layers of the soil; therefore, it should not be planted in saline, low-lying or wetlands, or where the groundwater is shallow. If you do plant rosehip in such a place, it will soon wither. If the soil on the site is acidic, then 12 months before the planting day it should be limed.

This shrub can be used both in group plantings and as a single plant. If you need to disguise an unsightly outbuilding or compost heap, then a rose hip bush is very suitable for this purpose. Also, such thorny bushes are used for planting around the perimeter of the garden. It should be remembered that this is a cross-pollinated plant, so the bushes should be planted not very far from each other.

How to plant rose hips

It is best to use two-year-old seedlings for planting. Before planting in open ground, the main roots should be shortened to 0.25 m, while all stems should be cut at a height of about 10 centimeters. If the site was prepared in advance and all the necessary fertilizers were added to it, then the depth and width of the planting hole should be approximately 0.3 m. If this was not done, then the depth of the hole is increased to 0.4–0.5 m, and width - up to 0.5–0.8 m, during planting of seedlings they are covered with soil combined with humus (10 kilograms per bush), you also need to add from 30 to 50 grams of potassium salt, from 150 to 200 grams of superphosphate and from 60 to 70 grams of ammonium nitrate. When planting a hedge, the distance between seedlings should be about half a meter. In other cases, the distance between plants should be about 100 cm. In order for rose hips to cross-pollinate normally, it is recommended to plant bushes of different varieties (at least three) on the site.

Before planting, the roots of the plant should be dipped into a clay mash, after which they are placed in a prepared hole so that the root collar of the plant is buried 5–8 centimeters into the soil. After this, the hole is filled with nutritious soil combined with fertilizer. When the bush is planted, the surface of the soil needs to be compacted a little, and then it is watered, using 8 to 10 liters of water. When the liquid is completely absorbed into the soil, its surface must be covered with a layer of mulch (sawdust, humus or peat chips).

PLANTING ROSE HIP. ROOTSTOCK.

Collection and preparation. How to dry rose hips

Fruits, seeds, roots, leaves, flowers, and branches of the plant are harvested for medicinal purposes.

Rosehip fruits (berries) are harvested when they acquire a characteristic color for the species, but are slightly unripe. In this form it is easier to collect them without fear of crushing them with your fingers. Rosehip leaves that fall on the fruit are not thrown away, but are used for brewing. The collection must be completed before frost, since in this case, when dried, the fruits lose most of their vitamins. Fresh berries can be stored for up to 3-4 days.

Dry the raw materials by spreading them in a thin layer in a well-ventilated area, remembering to stir them periodically. You can use a gas oven for these purposes, drying at a temperature not exceeding 40°C. Shelf life – 2 years. This is the best way to preserve rose hips for the winter.

Rosehip leaves and flowers are harvested during flowering. Shelf life: leaves – 2 years, flowers – one year.

Rosehip roots are dug in late autumn, cleared of soil, but not washed, cut into pieces and air dried. Shelf life – 2 years.

Not all types of rose hips have a high vitamin composition. When collecting fruits for this purpose, select species with a vitamin C content of at least 1%. This is the rosehip of Albert, Begger, Fedchenko, spiny, loose, cinnamon, Daurian, wrinkled.

Dog rose with a small content of vitamins is used to make the drug “Holosas”, which has a choleretic effect. This species is widespread in the southern regions of Ukraine, Moldova and the Caucasus. Its distinctive feature is that the sepals bend down after flowering and fall off long before the fruits ripen. That's why dog ​​rose does not have a hole at the top of the berries.

Origin and distribution area

It is believed that the birthplace of rose hips is the Himalayas and the rocky part of Iran. But today, thanks to their unpretentiousness and winter hardiness, its various species have spread widely across all continents, except the Arctic.

The most favorable growing conditions are the Mediterranean. But from the Arctic Circle to the Equator, on both American continents, in Australia and New Zealand, rose hips of various types are found everywhere. In mountainous areas it grows at an altitude of 2000 - 2200 m, and in more southern, tropical countries, it can grow at around 4 thousand m above sea level.

Bush forms of rose hips grow singly or in small groups. It is found on the edges of forests of all types, where there is a lot of sun. It grows well in undergrowth, as well as on the banks of lakes, rivers, along the outskirts of meadow lands, and on the sea coast. He likes to settle in dry ravines and sparse forests. There are species that form dense thickets in steppe and forest-steppe areas and can even inhabit deserts.

Chemical composition

Cinnamon rose hips are the champion among fruit and berry plants in terms of variety and quantity of vitamins. It contains the maximum amount of vitamins P and C (10-18%) valuable for the body. It contains 10 times more ascorbic acid (vitamin C) than black currants, 50 times more than lemons and 100 times more than apples. One to three rose hips can provide an adult’s daily requirement for this vitamin.

Rosehip vitamins are also represented by carotene (12-18 mg%), vitamins B1, B2, K, E, PP. Macro- and microelements include iron, potassium, manganese, phosphorus, calcium, and magnesium. In addition, sugars (up to 24%) are found in rose hips - glucose and fructose, pectin substances (up to 4%), citric and malic acids (up to 2%), flavone glycosides, kaempferol, quercetin, tannins and coloring substances, essential oil.

Rosehip leaves are not deprived of vitamins either. They contain up to 1.5% ascorbic acid. Essential rose oil is obtained from the petals of rosehip flowers.

Rosehip leaves, branches and roots contain up to 4.5% tannins.

The seeds produce valuable rosehip oil, rich in carotene and vitamin E, containing linoleic, linolenic, oleic, palmitic, and stearic acids.

Characteristic features of the bush

Rosehip is a perennial shrub; botanists classify it as a member of the Rosaceae genus. The shrub plant grows from 1 to 3 m. In the northern regions, the leaves fall off for the winter, and in the southern regions evergreen forms are found.

The branches usually have curved or straight thorns and numerous straight spines. Flowering shoots usually lack thorns.

In general, thorns are a distinctive feature of this plant, which gave it its name. They appeared as a result of evolutionary changes and the protection of rose hips from being eaten by mammals and herbivores. In turn, some of the animals managed to adapt to eating branches with thorns. For example, camels and many ruminants can easily cope with this.

Rose hips have flowers whose size ranges from 3 to 8 cm. The flowers usually have five petals on a small stalk with narrow, lanceolate bracts. When the berries ripen, depending on the type, the flowers either remain on the ripened fruit or fall off. Rosehip petals are colored in shades of red, pink, purple, and white. They grow solitary or collected in small inflorescences. Some varieties have very fragrant inflorescences, but occasionally they are completely odorless.

The bushes bloom in May, some species until July. Flowering occurs on two-year-old branches. Rosehip roots are very long, growing to a depth of 2-3 m. They are used as medicinal raw materials, as well as for preparing decoctions and infusions.
