Penstemon

The genus of perennials Penstemon is represented by subshrubs and shrubs. This plant is native to Central and North America. Domestic botanists classify the penstemone as a Norichnikov family, and foreign experts in the Plantain family, which includes more than 250 genera.

Features of penstemon

From Latin, the name "penstemon" is translated as "almost stamen". The fact is that the flower of this plant has only one unusual-shaped stamen, it is sterile and very long, due to which it protrudes far beyond the petals. The British call this plant "bearded tongue". Gardeners rarely grow such a flower in mid-latitudes. But every year the popularity of this culture is growing, thanks to its unusual shape, long flowering and beautiful foliage. Flowers appear on the bushes in the first days of June, and the duration of flowering can vary from 2 to 3 months. It is quite easy to grow such a culture in your garden, but this is only if you select the right site for it and provide it with the right care.

Planting and caring for penstemon outdoors

Seat selection

Penstemon is distinguished by its photophilousness. That is why a sunny area is most suitable for growing it. Also, when choosing a place for planting, pay attention to the fact that this flower reacts extremely negatively to drafts. The soil should be well drained and lightweight.

Growing seedlings

Penstemon is propagated by seeds, while growing it both through seedlings and in a seedless way. Sowing seeds for seedlings is carried out in February.To do this, take a seedling box and fill it with nutritious soil. Sow the seeds, and they are buried quite a bit into the substrate. Water the crops using a spray bottle. Cover the seeds with a thin layer of calcined sand on top, and then re-moisten the crops. And on top, cover the box with glass (film). Transfer the seed container to a well-lit and warm place. The first seedlings should appear after half a month. Taking care of crops is quite simple: they need regular ventilation (once a day) and a temperature of at least 20 degrees, and also do not forget to moisten the substrate if necessary.

When the first true leaves appear at the seedlings, they should be cut into peat pots. The grown seedlings are planted in the garden in the last days of May, and the soil and drainage are prepared in advance. At the same time, remember that the sooner you plant the penstemon bushes in the garden, the later they will begin to bloom.

Watering

Water such a plant systematically. Pay special attention to watering if there is a prolonged dry period. But do not let the liquid stagnate in the ground. To do this, water the bushes only when the surface of the soil dries out. In order to avoid stagnation of liquid in the root system of the plant, when planting seedlings in open ground, do not forget to make a drainage layer of fine expanded clay or coarse sand at the bottom of each planting hole. And in order to prevent moisture from evaporating from the ground too quickly, its surface around the bushes is mulched with a layer of dry peat or compost. Each time the plant is watered, remember to loosen the soil near it and remove the weeds.

Suitable soil

The soil on the site should be fertile, loose, allow water and air to pass through well, and also have high acidity. To improve the quality of the garden soil, it is combined with peat, fine gravel, compost or sand. And in order to achieve optimal acidity, when digging the soil, it is recommended to add charcoal to it.

Transfer

In order for penstemon to always be effective and neat, it is recommended to replant it regularly (once every 5 years). As a rule, the plant is transplanted in the spring. In this case, the transplantation procedure is combined with reproduction by dividing the bush. Remove the mature shrub from the soil and carefully divide it into several parts, while being careful not to injure the root system. Delenki are planted in a new area in pre-prepared holes, at the bottom of which a drainage layer must be made. Upon completion of the planting, the soil surface is slightly compacted, and then they are watered. Cover the planting with a layer of mulch. After about four weeks, the cuttings will completely take root.

Top dressing

The first time the bushes are fed during their landing in open ground. To do this, when digging the soil, compost is introduced into it. Also, plants are fed with organic matter, introducing it into the soil three times during the season.

Before the bushes bloom, they are fed with a complex mineral fertilizer, which contains a large amount of phosphorus. Thanks to this, the penstemon will bloom more magnificently and effectively.

Flowering features

Bushes bloom in June, while spectacular inflorescences, as a rule, decorate the plant throughout the summer period or until the first frost (depending on the species and variety). In some species, the flowers are outwardly similar to snapdragons, in other species they are bell-shaped. As a rule, the inflorescences are dense, large and racemose, they consist of white, blue, purple, yellow, pink, red or orange flowers. There are also varieties with bicolor flowers. When the flowering is over, seeds are formed on the plant, they can be used for subsequent sowing.

Pruning

In late autumn, while preparing the plant for wintering, cut off its stems completely.During the growing season, do not forget to systematically cut off all dried shoots, leaf plates, and also inflorescences from the bushes. If the flower has grown very much, it must be thinned out.

Preparation for wintering

Some of the species and varieties of penstemon are cultivated in mid-latitudes as a perennial plant. During the preparation of the bushes for wintering, the stems are cut off at the root, and the plantings are covered with a layer of spruce branches or dried foliage from above. In order to protect the root system of plants from stagnant melt water in spring, do not forget to make a good drainage layer at the bottom of the pits when planting penstemon, and also, with the onset of heat, throw snow from the site before it melts.

Breeding penstemon

Growing from seeds

Most often, gardeners propagate penstemone by seed. Seed material can be harvested from bushes in your garden, or purchased from a specialist store. It is recommended to sow them in open ground in autumn or spring, after the return frosts are left behind. Sow seeds in a previously prepared area, while sprinkling them with a not very thick layer of soil.

Seeds of some species of penstemon must be stratified before sowing (for example, alpine penstemon). To do this, they are sown in the garden in October or November, where they will undergo natural stratification in the soil in winter. However, experienced gardeners recommend sowing seed material in boxes, while sprinkling it on top with a thin layer of soil or sand. Crops are kept at room temperature for 20 days. During this time, the seeds will have time to swell. After that, the box is covered with 1 layer of lutrasil on top and transferred to the garden. Don't forget to secure the lutrasil or it could be blown away by the wind. For example, you can secure it with an elastic band by tying it around the container. Thanks to this shelter, weed seeds will not get into the substrate. Crops must be outdoors for at least 8 weeks, during which time the seeds will have time to stratify. If it snows, be sure to sprinkle the crops with it, because thanks to the melted water, the seedlings appear much faster. With the onset of spring, the crops are transferred to a warm room or a greenhouse, where seedlings will appear over time. As a rule, the first shoots appear in about a week and a half. However, some of the bushes you have grown from seeds may begin to bloom in the first year of growth.

Cuttings

First, prepare cuttings, for this you need to cut off those stems on which there are no inflorescences. After that, the lower part of the segments is treated with a solution of a product that stimulates root growth. In the garden, select an area in partial shade, and plant cuttings on it. Each stalk is covered with a plastic bottle from above, the neck of which is pre-cut. When the cuttings are fully rooted, they can be transplanted to a permanent location.

How to propagate by layering

Only undersized and weaving varieties can be propagated by layering. Select a stem, bend it to the surface of the soil and sprinkle with a layer of soil. The roots on the layer should appear in about 30 days, after which it is cut off from the parent bush, removed from the ground and planted in a new place.

Dividing the bush

In this way, it is most convenient to propagate penstemone during transplantation. First, remove the mature shrub from the soil, remove the soil from its root system, and divide it into parts. After that, the delenki are planted in pits, which should be prepared in advance. Remember that you can divide a bush only if it is already 3 years old. Younger bushes often die with this method of reproduction. All penstemon bushes must be divided once every 5 years, thanks to this you will be able to both rejuvenate the plant and propagate it.Do not neglect the rejuvenation procedure, since a plant older than five years begins to age very quickly: new stems cease to form in it, and inflorescences do not appear, which inevitably leads to a complete loss of decorativeness.

Diseases and pests

Often at the garden penstemon, the tops of the stems begin to dry out. If this happens to your plant, then cut off all its shoots at the root as soon as possible. If this is not done, then this can cause the death of the bush. Don't worry, the cut plant will grow new stems very quickly.

If you water the bushes too often and abundantly, it will lead to stagnation of fluid in the root system, which will cause the development of gray rot. Because of her, shoots begin to fade. At the first sign of illness, loosen the soil around the bush and spill it with a fungicidal solution. Penstemon is very resistant to pests, so they do not disturb him.

It is very easy to grow penstemon in your garden, even a beginner can do it. Such a plant does not have any special requirements for care, and it grows well in middle latitudes. Thanks to this, such a spectacular perennial is gaining more and more popularity among gardeners every year.
