Heliopsis is a genus that includes more than 10 annual and perennial resistant species of herbaceous plants, some of which are very decorative. Flowers appear in summer. Because of the similarity, albeit small, with a sunflower, it is called "false sunflower". Heliopsis buphtalmoides is an annual species 60-70 cm high with lanceolate leaves and yellow flowers. Sunflower heliopsis (H. helianthoides, or H. laevis) is a perennial species up to 70 cm high, with ovoid or ovate-lanceolate leaves and yellow flowers that reach 6 cm in diameter. There are varieties with flowers of a very intense yellow color. Heliopsis scabrous (H. scabra) is another perennial species 1.0-1.50 m high. This species got its name from its rough leaves and stems. Yellow flowers, up to 8 cm in diameter, simple in botanical species and double in garden forms and varieties (for example, 'Summer Sun'), with green median flowers contrasting with the marginal petals. They are very effective. But the cultivar 'Orange King' has bright orange flowers.

Cultivation

Heliopsis are grown in the garden in borders and flower beds. Perennial species are used primarily in mixborders, planting plants at a distance of 40-50 cm from each other in loose, fertile and well-cultivated soil; when planting, a complex complete mineral fertilizer of prolonged action is introduced at the rate of 40-50 g/m2. Perennial species are also fed in early spring.

Location

In the open sun or even in partial shade if the summer is very hot.

Temperature

Heliopsis are especially resistant to both high and low air temperatures.

Watering

Water it regularly in order to provide the plants, primarily in heat and during periods of prolonged drought, with sufficient moisture, but the water should not stagnate in the soil.

Reproduction

Usually the bushes are divided in spring or autumn, immediately planting the resulting parts on a permanent planting site in the ground.

Diseases

Plants are affected by grape powdery mildew (powdery mildew) - a whitish mold that covers the leaves. It is easy to get rid of it with sulfur, fungicides or special preparations against powdery mildew. The spider mite, which appears primarily in low humidity conditions, causes specks and cobwebs on the leaves on the underside of the leaves. In this case, treatment with acaricides is used. Some insect larvae feed on leaves. They are disposed of with the help of insecticides in granules, which are scattered on the ground.

Acquisition

Plants in containers that can be immediately planted in the ground in a permanent place are easy to find in specialized firms and horticultural centers. Make sure they are healthy and well developed.
