Veronica (lat. Veronica) Is a large genus of flowering plants belonging to the Legumes family. Previously, the genus was reckoned to the Norichnikov family. The species, in turn, are represented by herbaceous plants, dwarf shrubs and shrubs. There are more than 500 of them. Other names are snake, snake grass, Andreeva's grass. It is found everywhere in nature, but it grows in large quantities in the Mediterranean, South America and New Zealand. Typical habitats are light, moderately humid forests, meadows, steppes, forest-steppe. Some species are classified as weeds.

Characteristics of culture

Veronica is represented by annual or perennial grasses, dwarf shrubs and shrubs, equipped with a long, often branched rhizome, endowed with numerous thin roots. Some species have rather thick and creeping roots that form several shoots. The stem of most species of the genus Veronica is straight, less often prostrate, branched or single, it can be naked or pubescent over the entire surface. For example, Veronica ciliate has a stem covered with thick elongated hairs, while Veronica bush has a stem that is woody at the base.

Foliage in representatives of the genus Veronica can be alternate, whorled or opposite. The second type is the most common. The shape also varies and depends on the species, it can be ovoid, lanceolate, elliptical, narrow-lanceolate, oblong and triangular. There are also representatives with cordate foliage at the base and pinnately dissected foliage, while the degree of dissection in each species is very different. Some representatives of the genus are characterized by jagged foliage - serrate-toothed, obtuse-toothed, fine-toothed and crenate. The foliage, like the stem, can be bare or pubescent, often the pubescence is represented by glandular and ciliated hairs.

The flowers of the Veronica genus cannot be called large, they, in turn, are collected in apical inflorescences. In this case, the inflorescences can be umbellate, paniculate, spike-shaped, etc. For example, the latter form is inherent in the inflorescences of Veronica spicata and Veronica gray-haired. Pedicels can be either short or elongated, pubescent or glabrous. There are species with both dense inflorescences and loose ones. Bracts can be ciliated, whole, straight, lanceolate or linear, but the perianth in all species is double. The color of the flowers varies, it can be lilac, blue, white, yellow, red, etc. A similar situation is with the timing of flowering and fruiting.

Fruits in representatives of the genus Veronica are most often represented by two-celled capsules of an ovoid, reniform, elliptical or round shape. There are also species that form a unilocular capsule during fruiting. Bolls can be glabrous, slightly or strongly pubescent. The seeds are usually yellowish, flat or convex, wrinkled or smooth, ovoid or spherical. There are also species that form completely flat or boat-shaped seeds.

Growing features

Representatives of the Veronica genus for the most part belong to the category of unpretentious plants. They accept any type of soil, except for saline, overly heavy clayey and waterlogged. They are characterized by drought resistance, plants tolerate a short drought without any problems, although some species still require regular watering. If we talk about the location, then here it all depends on the species. Some feel great in semi-shady areas, and some do not tolerate their existence without an open location, that is, in the light.

Usage

Many species of the Veronica genus are endowed with healing properties, they are actively used in folk medicine for the preparation of tinctures and decoctions designed to fight various diseases. Some species are used for ornamental gardening, for example, for the formation of rockeries, alpine slides, mixborders, borders and other types of flower beds. Some of the species of the genus Veronica are suitable for decorating areas located near artificial or natural reservoirs, since they are moisture-loving representatives. Creeping species of the genus are used for landscaping orchards, to be more precise, they are planted near shrubs and trees in order to protect their root system from overheating, rapid evaporation of logs and weeds.
