Zinnia Flowers – Advantages and Peculiarities of Growing Zinnias

Zinnias are the epitome of the discrete beauty of a harmonious garden in its full bloom. But they have won our hearts (and gardens) not only because of their attractiveness. These flowers have several advantages over other annuals and perennials – a huge variety of colors and shades, different heights, depending on the variety, and special unpretentiousness in care.

Zinnia inflorescences are baskets, solitary, relatively large, apical, on long, usually thickened pedicels from above or sessile. The flowers are lingual and diversely colored: yellow, red, white, pink, purplish, lilac, densely arranged with a rounded or emarginate margin; inner ones are small, tubular. The fruit of the zinnia is a seed.

Two annual species, Zinnia elegans and Zinnia angustifolia, are used in landscaping. They gave rise to numerous varieties of garden zinnias, which are very diverse in their decorative possibilities. Zinnias are particularly popular in the United States. Most of the modern types were bred there. Americans have grown to love it for its resistance to heat and bright coloration.

Advantages of Growing Zinnias

At least five reasons explain the desire of many gardeners to have beautiful zinnias in their gardens. These are:

  • A whole rainbow of colors. These flowers come in all colors except blue, so they are easy to combine with perennials or annuals, deciduous plants, and grasses.
  • Any height. Zinnias come in tall and short varieties, making them easy to work with.
  • Minimal effort – maximum return. The unpretentious zinnias will be a joy to look at all season long without having to do anything to care for them.
  • A feast for birds and butterflies. Plant some zinnias, and you’ll see your garden come to life with an array of winged creatures.
  • Endless blooms. The more flowers you pluck from a zinnia, the more you produce.
  • Peculiarities of Growing Zinnias

    Zinnia is a heat and light-loving plant that cannot withstand freezing. For abundant prolonged flowering, it requires soil with enough nutrients with a neutral reaction. Plot allocated for the cultivation of zinnias, first dig over, and then add humus, compost, or leaf soil at a rate of 8-10 kg per 1 sq. m. Of mineral fertilizers, 1 tablespoon of superphosphate is added. It does not tolerate excess moisture in the soil or prolonged drought.

    Planting Zinnias

    Propagate zinnias through seedlings, as zinnias are sensitive to even the lightest frosts, both spring and autumn. Before planting, it is advisable to soak the zinnia seeds in a damp cloth to select the germinating seeds. Old ones germinate in about 6-10 days, and fresh ones in 2-3 days.

    Sown on the windowsill in peat pots in early April, embedding to a depth of 1 cm. The optimal germination temperature is 22-24 degrees. At the end of May, the seedlings are hardened by taking the plants to the balcony.

    Using Zinnias in Garden Design

    Used in flower beds, squares, groups, large masses, and for cutting. High-growing varieties are ideal for decorating flower beds and rainbows. For balconies and containers, medium and low-growing (15-20 cm) varieties are suitable. They are wind-resistant and bloom abundantly and continuously. Zinnias look especially good in a group.

    Flowers stand well in water and retain the brightness of color for a long time. They are cut when the inflorescence opens to 3/4, and the ends of the stems are burned or cut in hot water. A wilted bouquet of zinnias can be restored to freshness by placing it in hot water and renewing the oblique bottom cut.

    You can dig up low-growing zinnias before frost with a clump of earth, plant them in large pots, water them generously and keep them in a room on a bright window. Then they will grace your apartment for several more weeks.

    Zinnia is a well-known ornamental flowering plant. This beauty was first seen and discerned by the Austrian scientist Carl Linnaeus. He named the flower after the botanist scientist from Germany, Johann Zinn. From him, Linnaeus received an amazingly bright herbarium of zinnias. So in the 18th century, zinnia began its journey worldwide, and today is considered one of the most beautiful and favorite flowers. In the 20th century, new varieties of zinnias were bred by specialists in all continents worldwide.

    Many flower growers love zinnias for their bright flower heads and unpretentious nature. Most varieties grow well in direct sunlight and do not require frequent watering. Not every flower can survive in such extreme conditions. The only thing that Zinnia would like is low air temperatures. The plant will bloom from early spring until the first frost with proper care.


    Are zinnias afraid of the cold?

    Yes, returning frosts and lower temperatures can cause the death of the plant. This is why seedlings should be planted in the open ground when all night frosts have passed, and the air temperature is stable.

    What are the lighting requirements for Zinnias to grow?

    Zinnia refers to heat-loving and drought-resistant plants. The flower should choose bright, sunny areas, even with direct sunlight, and reliably protected from winds and draughts.

    How long does a zinnia flower last?

    Zinnia narrow-leaf blooms from late June until frost. It bears fruit. Seeds keep germinating for 2-4 years.
