Arnebia recumbent (lat. Arnebia decumbens) - a herbaceous creeping annual of the genus Arnebia (Latin Arnebia), ranked by botanists in the Borage family (Latin Boraginaceae). It differs from other species in its short life period (annual plant) and in its recumbent habits, preferring not to come off high from the surface of the earth.

What's in your name

The first word in the plant's Latin name is the generic name "Arnebia". The semantic load of the Latin word "Arnebia" should be sought in Arabic, and not in Greek, which happens much more often when deciphering the meaning of the name of plants. The Arabic word “arneb” is translated as “rabbit”, and the combination of two Arabic words “shagara el arneb” in translation means “rabbit tree”, or, more precisely, to the appearance of the plant, “tree - rabbit”. Although no trees can be traced among the plants of the Ernebia genus, for some reason the Arabs called such plants the word “shagara” (“tree”), adding the word “arneb” (“rabbit”) to it for the bristly appearance of stems and leaves. This is how the Latin name for the genus of plants "Arnebia" was born.

Since the Russian language is rich in synonyms, the Latin specific epithet “decumbens” is not translated into Russian as soon as possible. In the literature, you can find the following adjectives: recumbent, creeping, prostrate. Choose any that is in tune with your soul.

Description

Arnebia recumbent is a herbaceous annual plant. Its vertical thin root goes deep into the soil or into the crevices of rocky slopes in order to extract nutrients in not the most favorable conditions of life.

As a rule, an erect stem (straight or branchy-spread) rises to a height of 5 to 20 centimeters. Linear-lanceolate or lanceolate leaves in the lower part of the plant are larger, with a blunt end, higher leaves are smaller and sharp-nosed.

The stems and leaves are covered with hairs, the density of which depends on the surrounding living conditions. The hairs are divided into two types: the bristly hairs are longer and arranged horizontally, the soft hairs are shorter and are pressed against the surface of the stem or leaf plate. With dense pubescence, the green color of the leaves turns into grayish-silver. The lower leaves practically lie on the surface of the earth.

Hairy bracts are similar to stem leaves. The yellow tubular corolla of the flower is covered with hairs outside. The lobes of the flower are round-ovoid, sometimes decorated with dark spots, like Arnebia beautiful (lat. Arnebia pulchra) and Arnebia spotted (lat. Arnebia guttata). Flowering lasts from March to May.

The fruit is small-tuberous gray nuts, with a sharp nose, oblong-ovoid. The fruits ripen from May to July.

Like many species of the genus Arnebia, this plant is found on rocky and sandy soils, poor in nutrients. This does not prevent the plant from being decorative and graceful.

Arnebia recumbent has a fairly wide range, including a number of Asian countries (China, Mongolia, Iran); Western Siberia; the European part of Russia; countries of North Africa.

Growing conditions

Like most plants of the genus, Arnebia recumbent prefers to grow in the open sun.

In relation to the nutritional value of the soil, Arnebia recumbent refers to mesotrophs, that is, to plants that are quite satisfied with soils with a moderate content of chemical elements. Therefore, growing it in a rocky garden of a summer cottage, you do not need to worry about mineral fertilizing.

In relation to moisture, Arnebia recumbent is a xerophyte, that is, a plant that lives on dry soils that can withstand prolonged drought. It is very important for such plants to prevent the formation of stagnant water, which is detrimental to their life.
