History and description of the hairy rudbeckia species
As soon as the first white colonists began to develop American lands and build their settlements, one of the first decorations on their front gardens was rudbeckia. And the seeds of this flower were sent home to Europe. Here the famous taxonomist Karl Linnaeus was engaged in the study, description and definition of the plant. From him the family got its name in honor of the teacher Linnaeus Olaf Rudbek.
This man had versatile scientific interests, one of the first to discover the lymphatic system in the human body. And although this does not apply to plant taxonomy, he was the great-grandfather of the founder of the Nobel Prize, A. Nobel. In total, the genus rudbeckia includes about three dozen species. They all exist in herbaceous form as annuals or perennials.
Rudbeckia hairy or rudbeckia hirta is most often grown in gardens as an annual, since in the first year its flowering is most spectacular, in a two-year form, attractiveness is still preserved, when grown as a perennial, many varieties lose ornamental qualities or the plant dies altogether. The stems of the hairy rudbeckia are straight, with well-developed branches and hard pubescence.
The height of the stems depends on the variety, most often from 0.5 m to 0.9 m. The upper leaves are mainly sessile, narrow, lanceolate, the lower ones have a winged petiole, rather large, up to 10-13 cm in length. Inflorescences are baskets. They are located singly. The marginal flowers are sterile, ligulate, their main color is yellow, dark yellow, brown.
The median flowers are tubular, the color is black, dark brown, dark brown. There are varieties with both simple and double flowers. The diameter of the inflorescences is from 5 to 15 cm. Hairy rudbeckia is widely used in breeding work and many varietal and hybrid varieties have been obtained from it. Grown everywhere, well tolerates the climate of Siberia, the Far East. We will try to find out where it is better to plant hairy rudbeckia.
Choosing a place on the site for rudbeckia, planting
Places with very good sunlight are perfect for rudbeckia. As a last resort, it can be placed where the sun illuminates the area for most of the day. If you plant rudbeckia in a light shade, then the stems of the plant will rise slightly higher than the declared varietal sizes. In addition, these plants require less moisture, bloom a little longer, and the color of the inflorescences may be softer. The best soil for rudbeckia hairy will be light, well-permeable loams.
Propagated by rudbeckia and seeds, and by dividing the bush. By sowing seeds, it is better to grow varieties with simple flowers, and for plants with double inflorescences, it is more convenient to use the division of the bushes to preserve the properties. Sowing rudbeckia seeds is usually straightforward. In the last decade of March - early April, prepared boxes are filled with neutral soil.
The seeds are spread over the surface. They are lightly sprinkled with the same soil on top. The temperature for germination should be + 18 + 20 degrees. The emergence of seedlings can be expected in 12 - 14 days.
After about four weeks, it is advisable to plant the seedlings in separate containers. In open ground, rudbeckia hairy is planted at the end of May. When transplanting, you need to take into account the size of adult bushes and it is advisable not to place the seedling closer than 0.3 - 0.5 m from each other. Perhaps at night during the rooting period, the rudbeckia will have to be covered with lutraxil from frost. Flowering can be expected by the month of July. Flowering is long, in some varieties it lasts until the end of September.
