Zinnia plant is a representative of the family of Asters. It is represented by perennial herbaceous plants and shrubs. The homeland of this plant in southern Mexico.
The Aztecs began to grow the plant with 1500 g, and in Europe, this plant appeared only in the 18th century, while it almost immediately gained great popularity among gardeners, they have decorated not only garden plots, but also aristocratic techniques.
It was even a symbol of the state of Indiana (USA) in 1931-1957. This culture is so popular because it is very effective and undemanding to the growing conditions.
Features of Zinnia
The height of the Zinnia Bush directly depends on what kind and variety it belongs to and can vary from 0.2 to 1 ft. Inflorescences are single apical baskets, which in diameter can reach 3 – 14 in, they are placed on a relatively long peduncle. Small tubular middle flowers in inflorescences have a brown-red or yellow color. The fruit is an achene with a tuft.
The beginning of flowering falls in the second half of June, and it ends with the first frosts. Zinnia is resistant to both drought and heat. It is grown as a spectacular garden plant, which is characterized by its unpretentiousness, as it stands perfectly in the cut. It is also grown in flower beds with other more noble flowers.
Growing Zinnia From Seed
Both perennial and annual Zinnia can be propagated by seed (generative) method. Sowing of seeds can be carried out directly in open soil, but only in those regions where the climate is mild, while in may there should be no frost. In colder regions.
Zinnia is grown only through seedlings, because if the air temperature drops to at least minus 1 degree, the seedlings will freeze. Gardeners, with considerable experience, are confident that the grown and hardened seedlings of Zinnia after transplantation into open soil, will take root very well and quickly move into growth.
Before you start sowing, the seeds should be prepared. To do this, they are wrapped in gauze or cloth, which is well moistened with EPIN solution. This will help to separate the germinating seeds from the non-germinating ones.
If the seeds are freshly harvested, they will hatch very quickly (after about two days). In this case, the old seeds will need about 7 days. After the seeds are sown, the surface of the substrate must be moistened. Then the containers are transferred to a well-lit and warm (from 22 to 24 degrees) place. If the seeds are sown in compliance with all the recommendations, the first seedlings will have to appear after a few days.
Planting Zinnias In The Open Ground
Experienced gardeners advise to plant seedlings of Zinnia in the open soil in the second half of May, however, it should be noted that the return spring frosts should be left behind since this culture is quite thermophilic.
For planting, you should choose a well-lit area, which should have reliable protection from the wind. The soil should be the fertile, well-drained and neutral reaction. Before planting seedlings, the site should be prepared and, if possible, it should be done in the autumn. To do this, it is due to a depth of 0.45 ft, removing all the weeds, while the soil needs to be composted, deciduous humus.
Care Of Zinnia In The Garden
Caring for Zinnia grown on a garden plot is quite simple. Planting should only be timely weeding, loosening the surface of the soil on the site, and still abundantly watered, and this should be done under the root since it should be excluded from entering the liquid on the flowers. After the bushes bloom, you should make their regular inspection, in order to timely remove the flowers that began to wither.
This herbaceous annual plant can reach a height of 100 ft. Simple inflorescences can be colored orange, white or pink. Straight, usually not branched, the shoots of circular cross-section, the surface has hairs consisting of stiff hairs. On the upper parts of all stems, apical inflorescences-baskets are formed.
Whole-edged sessile leaf plates have an egg-shaped and pointed tip. In length they reach from 50 to 70 in, and in width ― from 30 to 45 in. On the surface of the leaves is also pubescence. Inflorescences in diameter reach 5-16 ft, they can be semi-double, simple and Terry.
They are composed of red flowers, reaching a length of 40 in, and width ― 15 in, they can have a variety of colors, but not blue. Also included are tubular median flowers, painted in brown-red or yellow. The beginning of flowering is in June, and it ends with the first frosts.
Powerful compact or spreading bushes in height can reach 0.6–0.9 ft. Shoots they have of the first order. Large leaf plates reach a length of about 12 ft. Terry hemispherical inflorescences in diameter reach about 14 ft. Varieties:
- Violet ― Terry variety, reaching a height of 0.6–0.75 ft, dense inflorescences can be painted in a variety of shades of purple;
- Orange Koenig ― Bush height 0,6–0,7 ft, Terry inflorescences in diameter reach 14 ft, and they are painted in orange-red;
- Polar bear ― compact Bush height of about 0.65 ft, they are painted white with a greenish tint.
The height of this branched compact Bush is not more than 0.55 ft, it has many shots of the second, third, and fourth-order. Leaf plates are small. Inflorescences are relatively small, so in diameter, they reach only 50 in, and the shape they are similar to the pompom on the cap. Tsinia fantasy
The height of compact bushes is almost spherical about 0.5–0.65 ft. Sheet plates are large. Curly loose inflorescences consist of narrow reed flowers, rolled into tubes and curved in various directions, some of them are bifurcated at the tips.
Zinnia Haageana or Zinnia Angustifolia
The homeland of this species in Mexico. This erect plant is an annual, which forms branched bushes. Sessile acuminate leaf plates are oblong or lanceolate forms. Small deep-orange blossoms can be double or simple.
This type is most often used for the formation of landscaped flower beds. Bush height of about 0.6 m, elbow thin shoots colored in pale red. Across a small inflorescence, up to 30 mm. Purplish bent narrow ligulate flowers have twisted the ends.
This type can be easily confused with narrow-leaved Zinnia, because its leaf plates are thin and sharp, like the tips of manicure scissors. This species is the smallest of those cultivated by gardeners. The spherical bushes reach a height of 0.35 m. the Inflorescence is also small. Yellow reed flowers have an orange edge. Such a flower is most often grown in balcony containers, in small flower beds, in pots, and on the Alpine slides.
