Veronica - for rocky gardens retaining walls and curbs
The origin of the name of the plant Veronica is explained in different ways, some believe that they named it in honor of Saint Veronica, others that it comes from the Latin "vera unica", meaning - a real medicine.
The genus Veronica includes about 300 species, which are distributed in almost all parts of the world, but most widely in Europe (mainly in the Mediterranean) and Asia.
In Russia and neighboring countries, there are about 150 species. These species are represented as annual, biennial and perennial grasses, and sometimes dwarf shrubs.

Veronica's stems are straight, sometimes outstretched with opposite leaves, less often the arrangement is alternate or whorled.
The flowers are medium-sized, often white, less often blue or blue, sometimes pink, collected in lateral or apical carpal or spike-shaped inflorescences.
The most common Veronica is often found in the forest or in the meadow, and it is easy to recognize it by its delicate thin and bluish petals, sometimes marked with a white spot in the center.
Veronica is a plant very often used in garden design as an element of alpine slides. Here are the most common types of Veronica:
Veronica Austrian - comes from the edges of forests and semi-arid meadows in Europe, the Caucasus, Asia Minor and Siberia. It is a perennial that reaches half a meter in height. The form of the plant is a bush growing from the rhizome. Interesting leaves - elongated, oval, jagged along the edges, juicy green color. The flowers are collected in dense ears, pleasing to the eye in May-June. The only drawback is that it does not tolerate damp areas and can withstand low temperatures only up to - 23 ° C degrees.

Veronica virginskaya - originally from the east of North America, where plants reach a height of 130 centimeters, the bush is quite stable with juicy green, whorled leaves and white or blue flowers collected in a paniculate inflorescence. This species is most decorative during the flowering period from June to August.
Gentian Veronica - naturally grows in the middle and southern regions of the European part of Russia, in the Crimea, in the Caucasus and in Asia Minor. Veronica gentian is a low, herbaceous plant that forms cushion-like bushes, reaching 45 centimeters in height.

During flowering, the bushes are spreading, later cushion-shaped. The leaves are broadly lanceolate, white-tomentose on both sides and opposite. Inflorescences are dense, apical, racemose, reaching a length of five centimeters. The flowers are very decorative, bright blue. Flowering begins in late July and lasts 35 days. It winters freely and is successfully combined with primroses, as well as low and tall perennials.
Veronica broadleaf - grows naturally in the mountains of Southern and Central Europe. The plant reaches a height of 50 centimeters, has small, whole, bare on top and pubescent below the leaves and flowers of various colors (from blue to white), collected in dense racemose inflorescences reaching a length of 7 centimeters.

Veronica is crushed. A distinctive feature of the species is the presence of a long rhizome, with the help of which the plant is kept on gravelly soil. The plant is not tall, the height of the rising stems is 20-25 centimeters. The flowers are pale blue, collected in long brushes, bloom in June-July and bloom until autumn.
So, we examined the most common types of Veronica, now let's talk about choosing a place for planting them, about the technology of cultivation and reproduction, and also about the use of this plant.
Veronica is not very demanding on the conditions of existence, but they are photophilous. In addition, some species are also moisture-loving, for example, Veronica Virginia long-leaved, gentian, and mountain species, such as Veronica spikelet, crushed stone and Austrian, are also drought-resistant.
All types of Veronica are absolutely not picky about the type, composition and quality of the soil, so ordinary garden soil is suitable for them. As for Veronica spikelet and crushed stone, for their better rooting and a long full life, crushed stone must be added to the soil.
Immediately after flowering, the shoots must be cut off, and the bush will be renewed due to the new growth of leaves. As for caring for plants in winter, there is nothing to worry about, all types of Veronica covered for the winter are not required.
Veronica, like most plants, is propagated by dividing the bush, stem cuttings and seeds.
Reproduction by dividing the bush is perhaps the easiest way of vegetative propagation, since it has a fibrous root system and a large number of shoots, an adult bush can be cut into several divisions, depending on desire. It is better to do this in early spring, when the leaves are just beginning to unfold, but it is possible in August, however, there is a risk of losing the plant. When transplanting to a permanent place, part of the plant is cut off. The final distance between plants depends on their size.
The most difficult is the method of propagation by green cuttings. It consists in the following: in June-July, young, but rather elastic shoots are chosen, of which cuttings 4-6 centimeters long with one or two internodes are cut. Then they are planted in a greenhouse under a film in a substrate of fertile soil, on top of which sand is poured with a layer of 5-7 centimeters. When planted in June, roots form in September. The resulting rooted cuttings should be immediately transplanted into the ground, and only next fall you will receive full-fledged planting material.
Seeds are sown in the fall in the ground, and in the second year the seedlings bloom.
Veronica is used for a variety of rocky gardens, retaining walls, curbs, and so on. Many species, among other things, are also very good ground cover plants, as they form very dense turf. For example, Veronica gentian looks very good in small reservoirs located next to rockery, and Veronica entrusted is used to mask the edge of the pond.
Almost all of its types look great both in group and in specimen plantings. But there are also some differences. For example, Veronica gentian looks very good together with various primroses, gravilat, bells; veronica spikelet and crushed stone is successfully combined with saxifrages, stonecrops, carnations, as well as Dalmatian geraniums. As for the big Veronica, it is most convenient to plant it next to a white cornflower, a pinkish-lilac letter, a peach-leaved bell and a red-orange gravilat.
There are root, leaf and petiole varieties celery. In root varieties, nutrients and aromatic substances are more concentrated in the root, in leafy and petiole varieties, respectively, in the upper part of the plants, but this subdivision is to some extent arbitrary. Root celery forms fleshy, well-developed root crops weighing up to 500 g. Their shape is from round -flat to nearly spherical. The pulp is sometimes void. I cover the fibrous lateral roots in most varieties
Fennel is one of the world's favorite spice plants. Distinguish fennel ordinary, or pharmaceutical dill ( Foeniculum Vulgare Mill. ), and vegetable or sweet fennel, Italian ( Foeniculum Vulgare ssp. Vulgare ( Miller ) Thell. )
Ornamental garden - decoration of your siteUnfortunately, vegetables and flowers on our sites, as a rule, are diametrically opposed concepts. However, many flowers can be used for cooking and many vegetables for decorative purposes. For example, tomatoes and potatoes imported from America were first planted in flower beds, and not in garden beds
The Siberian land is rich in wonderful plants. But, perhaps, one of the first in this list should have been our Siberian badan! In the mountains of Southern Siberia, it forms continuous thickets - badanniks - with an area of several square kilometers
