A genus of herbaceous annual and perennial plants, Heliopsis is a member of the family Asteraceae or Asteraceae. In nature, they can be found in North and Central America. The name Heliopsis plant is translated as "sun-like", this is because the shape of the inflorescence is very similar to the real sun. This genus includes more than 10 species. The typical species of this genus is Heliopsis helianthoides, and it is its hybrids and varieties that are most often cultivated by gardeners.
The branching and straight shoots of heliopsis are about 1.6 m high. The oblong leaf plates are either suproposed or alternately arranged, with a serrated edge. Lush panicles consist of inflorescences, which are hemispherical, simple or tumble baskets, reaching 80-90 mm in cross-section; they consist of yellow or orange lingual flowers and also median tubular flowers, which may be orange, yellow or brown. The fruit is a bare, flat-shaped seed.

Growing heliopsis from seed
Gardeners grow heliopsis both through seedlings and sow its seeds directly into open soil. Sowing seeds in the open ground is carried out in the middle of the spring period or deep autumn, with the seedlings sown in the last winter weeks.
If you decide to grow such a flower through a seedling, then prepare a soil mixture, which should include coarse sand, turf soil and peat (1:1:1). It should be half a month before sowing the seeds should be poured strong solution of potassium permanganate, and then the container top covered with glass or film. Immediately before sowing the earth mixture is poured into a box with holes at the bottom for drainage, also do not forget to make a good drainage layer of clay pebbles.
Level the surface of the substrate and distribute the seeds evenly, then the container from above is covered with glass or film and transferred to a well-lit and warm (about 20 degrees) place, where it will stay for 7 days. Keep in mind that the seeds need bright but diffused sunlight. After that, the seeds are moved to a cooler place (3 to 4 degrees), where they will stay for 30 days, during which time the seeds will undergo cold stratification. When the allotted time is out, the container is moved to a warm place (25 to 28 degrees). Do not forget to systematically remove the cover for airing, and also from its surface must necessarily be removed accumulated condensate.
The cover from the container is removed only after the sprouts begin to form true leaf plates. Prick the plants during the formation of their first pair of true leaf plates. For this purpose, peat cups are used, which should be filled with substrate (its composition is described above). Picked flowers should be moved to a fairly cool place (from 13 to 15 degrees). Taking care of these seedlings is very easy, requiring timely watering as well as systematic careful loosening of the soil mixing surface.

When to plant
Putting heliopsis seedlings into open soil only after the threat of return frost is left behind, more precisely, from the second half of May to the first days of June. For planting, it is recommended to choose a well-lit site with reliable protection from draughts. The soil should be clayey, but also well permeable to water and air. To do this, on the plot where heliopsis will be grown, a twenty-centimeter layer of crushed stone should be placed under the soil and backfilled with sand. The levelled layer of drainage must be covered with clay soil previously combined with compost.
In the prepared area, planting holes must be made with a distance of 0,3 to 0,5 m between them. Their depth should be such that the root system of the plant taken together with the root ball can be freely accommodated. After the seedlings are planted, fill all the holes with the necessary amount of soil, which is tamped and moistened. When growing strong-growing varieties, be sure to place supports near the bushes during planting.
Heliopsis care in the garden
Care for Heliopsis grown in open soil the same way as most garden crops.
To do this, the bushes need timely watering and weeding. And for them to stay showy as long as possible, the tops of the stems should be pruned in order to stimulate tillering and also to remove flower buds starting to fade, if necessary, formative pruning and tying to a support made of a wooden spike, a metal bar or a metal netting frame should be done in time.
If this crop is grown in the same place for several years, it will gradually grow and begin to displace other garden plants from their designated areas. To avoid this, the flowers should be removed from the soil once every 5-7 years, divided into parts, which are planted in separate holes in a new plot.
This flower is characterized by its resistance to drought, so it does not need frequent watering.
It tolerates the heat very well and will not wilt during a long dry period. However, if the heliopsis will feel the lack of liquid for a long time, the flowering will be sparse and relatively short. Therefore, during prolonged drought, the shrubs should be watered regularly (two to three times in seven days), either in the evening or very early in the morning. For watering, use water that has warmed up well in the sun. After this procedure, the soil surface near the flowers is gently loosened.
Feeding begins in the second year of growth and is done regularly once every 4 weeks. Organics and mineral complex fertilizer for flowering plants are used alternately. During the first season, the plants will feed on the substances that were applied to the soil during site preparation.
If cared for properly, the plant will not finish flowering until the second half of the autumn period. Before frost sets in, the above-ground part of the shrub should be trimmed flush with the surface of the plot.
It is not necessary to cover the bush root system for the winter.
Diseases and pests
This plant may suffer from black aphids. If there are still very few pests on the bush, you can get rid of them with harmless infusions of tomato, celandine, nightshade or wormwood, remember to pour in some liquid soap before spraying. If the aphids are very numerous, they can only be treated with insecticide preparations and the most damaged bushes should be dug out and destroyed.
Heliopsis can also be harmed by fungal diseases such as rust and powdery mildew.
If a grayish-white bloom appears on the above-ground part of the shrub it means it is infected with powdery mildew, brown spots on the leaf plates indicate rust infection. To save the plant, spray it several times with a solution of Bordeaux mixture (2%) or copper sulfate and other fungicides such as Fundazole can also be used.
Heliopsis is very resistant to other diseases and pests.
Heliopsis species and varieties
We have already mentioned above that sunflower heliopsis is most often cultivated by gardeners, but also its varieties, varieties and hybrids.
Heliopsis sunflower (Heliopsis helianthoides)
Or heliopsis sunflower-like, the shoots of this perennial plant are bare straight and branched, reaching a height of about 100 cm.

This is a variety of Sunflower heliopsis, which is a plant about 150 cm high. The upper part of the branched shoots is rough and it will eventually become woody.
Short-cellular supropode leaf blades ovate or oblong-oval in shape and serrated along the edge. Inflorescences of the basket reach 60-70 mm in cross-section, they consist of yellow tubular and golden lingual flowers. This plant began to be cultivated in 1819.
