Video: Perennial Sunflower, Ten-petal. Care, Cultivation, Reproduction. Decorative Blooming Flowers. Garden Plants. Photo
Sunflower was brought to Europe by the Spaniards from North America at the beginning of the 16th century. Then it looked a little like the powerful single-stem plant known to everyone today with one flower basket at the top, sometimes reaching half a meter in diameter. The Europeans saw a bush with a height of 2-3 m with many stems, on the tops of which there were also numerous small (2-3 cm in size) flowers of light orange color.
Florists began to improve the decorative properties of sunflowers, and terry, semi-double, dahlia and chrysanthemum forms of flowers of different colors - from almost white to cherry red - appeared. Of the perennial species, the ten-petalled sunflower is the most decorative today.
I liked the perennial variety of sunflower that bloomed at my neighbor's entire second half of the summer. In the fall, I asked her for pieces of rhizomes and planted them, burying them 3-4 cm in the soil. With the onset of cold weather, the planted bushes were covered with humus mixed with sawdust. In early spring, the mulching material raked and fed the awakening sprouts with a mullein diluted with water in a ratio of 1:10.
The plants grew well and by the middle of summer they formed 8-10 inflorescences, which bloomed at the same time. The plants themselves were low - up to 50 cm, but formed a lot of side shoots. If you grow a terry sunflower through seeds, then it is necessary to thin out the shoots at least after 45-50 cm, it is too painful for them to grow. But on the other hand, how pleasant it is to look at the golden-yellow terry caps of the inflorescences, although they, of course, are smaller than those of an annual sunflower, and the seeds do not form well in our conditions.
During the period of prolonged rains, individual bushes were affected by bacteriosis, their leaves had an unkempt appearance, but the stems were stable until the end of the growing season. I tried to leave some inflorescences for seeds, but now I understand that it was not worth doing. The seeds still have not ripened, and the decorativeness of the bushes has noticeably decreased. In order for a stunted sunflower to always look beautiful, it is necessary to remove faded flowers and diseased leaves in a timely manner. Caring for it is the same as for ordinary sunflower: twice a season it is necessary to feed it with a diluted mullein with the addition of 20 g of potassium sulfate to a bucket of water. At the end of the growing season, after repeated frosts, the plants must be cut at a height of 5-7 cm from the ground (the upper part can be put into compost). After 3-4 years, the bushes will grow significantly, and then they must be divided, otherwise the flowers will become smaller.And yet, the perennial sunflower is very fond of sunny areas, where it forms flowers faster and blooms for a long time.
