Rudbeckia (lat. Rudbeckia) - flower culture; an annual or perennial belonging to the Asteraceae family. The homeland of rudbeckia is North America. More than 30 species are currently known.
Description
Rudbeckia is represented by herbaceous plants with erect, strongly branching stems, which reach a height of 3 m. The stems bear a whole-edged, less often dissected, rounded-oval or ovoid green foliage. Leaves located at the top of the stem are sessile; the foliage located below sits on long petioles.
Inflorescences in the form of large baskets, 18 cm in diameter, consist of tubular and ligulate flowers. Reed flowers, depending on the species and variety, can have a wide variety of colors: deep red, bright yellow, yellow-orange, red-orange, yellow-brown. The middle of the inflorescence is usually convex. The receptacle is cylindrical. The fruits are represented by elongated achenes with a crown.
Features of cultivation
Rudbeckia cannot be called a whimsical culture, but in order to obtain lush bushes and abundant flowering, it is recommended to plant it on nutritious, neutral, loose, light, permeable soils. The location is preferably sunny or with an openwork shade. Thick shade negatively affects flowering.
Subtleties of reproduction
Rudbeckia propagates by seed and dividing the bush. Rudbeckia is most often grown in a seedling method, sowing for seedlings is carried out in the first decade of April. Crops are moistened abundantly and covered with polyethylene until the first green shoots appear. The optimum temperature at this moment is 20C. With good care and microclimate, seedlings hatch through the soil after 15-18 days. Seedlings are transplanted into the ground in the first decade of May. Before planting, the seedlings are hardened.
Care
Rudbeckia needs systematic irrigation with settled and warm water. Excess moisture negatively affects the development of plants, waterlogging should not be allowed. Rudbeckia does not tolerate drought and heat. Tall forms require support. A culture of fertilizing with mineral fertilizers is necessary (twice a season: in spring when planting and during flowering).
Usage
Rudbeckia is actively used in gardening. The culture is beautiful both singly and in groups, and in alliance with other floral cultures. Rudbeckia is cultivated in flower beds of various types, and is also used for cutting.
Popular types
* Rudbeckia bicolor (lat. Rudbeckia bicolor) - characterized by annuals that form lush bushes in the process of growth, bearing baskets with reed flowers of yellow, red and brown color, often with spots and patterns.
* Rudbeckia rough (lat. Rudbeckia hirta) - characterized by perennials that form lush bushes in the process of growth, bearing baskets with a diameter of 10-17 cm with reed flowers of red, orange, yellow and brown color. Boasts long flowering
* Rudbeckia radiant (lat. Rudbeckia fulgida) - characterized by perennials no more than 70 cm in height, forming lush bushes in the process of growth, bearing baskets with reed flowers of yellowish-orange color. Blooms from late summer to late autumn.
* Rudbeckia purpurea (lat. Rudbeckia purpurea) - characterized by perennials that form lush bushes in the process of growth, bearing baskets up to 12-14 cm in diameter with ligulate flowers of purple or light purple color. The species blooms all summer.
* Rudbeckia dissected, or split-leaved (lat. Rudbeckia laciniata) - is characterized by perennials that form tall lush bushes in the process of growth, bearing baskets up to 10 cm in diameter with reed flowers of golden and rich yellow color. The species blooms all summer.
