Elegant zinnia (Zinnia elegans), also called Jacobinka, it is grown mainly as a cut flower. It has thick stems, stiff, brittle. Heart-ovate or elongated leaves, rough, opposite, include the stem. Inflorescences, in the form of a basket with a diameter 4-15 cm, they can be single or full, about colors: white, creamy, yellow, orange, golden yellow, carmine, pink, scarlet, red.
Zinnia bloom from July to October. They bloom more or less after 3 months from the time of sowing. Medium height zinnia are most often grown (about 40 cm), suitable for rebates and cutting. Specially intended as a cut flower, tall varieties are planted (80-100 cm), with very large flowers. There are also dwarf zinnias (15-20 cm), forming compact, almost spherical bushes.
Zinnias require very fertile, well-fertilized and moist soil and a sunny position.
The seeds are sown in March or April for a semi-warm inspection (poorly heated). You can also try to sow tin in late March in boxes in the apartment. After germination, they first appear 2 cotyledons, then the first leaf. At this point, the zinnia should be quilted with a 5X5 cm spacing. A good way to prepare zinnia seedlings is to plant the seedlings in pots, preferably earthen. During emergence and in the seedling phase, the temperature should be kept at around 18 ° C. Tin is planted permanently in the ground at the end of May, in spacing: for low varieties – 15X20 cm, for tall – 30X40 cm. It is also possible, if we don't care about early flowering, sow it in May directly into the ground. The plants must then be discontinued, keeping the above-mentioned distances.
As a result of breeding, many forms were obtained that differed in size of inflorescences, the arrangement and shape of the flowers, as well as the power of plant growth.
We distinguish among them:
