One of the simplest flowers to plant, zinnias grow quickly and provide a lot of blooms. Additionally, they will continue to bloom right up until the first fall hard frost. Consider trying zinnia flowers this year to add a huge splash of color to your yard.
About Zinnias
Since zinnias are annuals, they will only produce blooms and seeds for one season before dying. The original plant will not reappear the following year. They are excellent for use as a cutting flower or as food for butterflies since they have vivid, solitary, daisy-like flowerheads on a single, tall stem.
Types of Zinnias
Zinnia elegans, the most widely grown zinnia species, has been developed to produce a large number of distinctive variants.
Single, semidouble, or double zinnia blooms are the three most common varieties. The number of petal rows and whether or not the flower’s center is visible serve to distinguish between these forms:
- A single row of petals and the center are both visible on single-flowered zinnias.
- Petal rows abound on double-flowered zinnias, and their centers are hidden.
- Between the two are semidouble-flowered zinnias, which have several rows of petals but discernible cores.
In addition to these shapes, zinnia flowers also occur in “beehive,” “button,” and “cactus” forms. Additionally, the plants themselves come in various heights: taller types function best as a garden bed’s background, while shorter varieties are useful as a border. There is a zinnia for every garden, in fact!
In an annual or mixed border garden, plant zinnias. Smaller zinnias work well as window boxes, edging, or in other containers.
To have a lot of flowers all season long, choose a place that receives full sun (6 to 8 hours of sunlight every day). Additionally, later in the season, foliar diseases like powdery mildew can be avoided by planting in an area with sufficient air circulation.
Although zinnias can grow in a variety of soil types, they prefer organically rich, well-draining soil. The optimal pH range for soil is between 5.5 and 7.5. The blooms will grow more quickly if compost (humus) is added to the soil. Find out more about soil improvements and getting the soil ready for planting.
When to Plant Zinnias
- Because they dislike being transplanted, it is advised that you start your zinnia plants from seed directly in the garden bed. If the correct circumstances are present, they will develop quite quickly from seed.
- It should be noted that zinnias can be grown from seed inside if you like. Just make sure to transfer them gently and young.
- Because zinnias are delicate to frost, wait to plant them until after the last frost in your area. See the frost dates in your area.
- Zinnias can tolerate daily temperatures as low as 60F (16C), although a range of 7484F (2328C) is ideal.
- To prolong the flowering time, sow a new crop of seeds every week or so for a few weeks.
How to Plant Zinnias
- Depending on the kind, place plants 4 to 24 inches apart. (Many common kinds are planted 2 feet between rows and 6 inches apart within the row.) For information about each variety, consult the seed packet’s back.
- Plant zinnia seeds no deeper than 1/4 inch.
- The majority of zinnia cultivars will produce seedlings in just 4 to 7 days, but it may take up to two months or more for blooms to appear (depending on planting site and climate).
- To promote air circulation, thin seedlings when they are three inches tall, spacing them 6 to 18 inches apart. As a result, powdery mildew is less likely to grow.
- To promote development and blossoms, keep the soil’s moisture level moderate and apply a mild fertilizer.
- Deadhead zinnias once they have finished blooming to facilitate the development of new blossoms.
- Since zinnias are annuals, they will perish with the first fall hard cold. Let the final blooms of the season fully mature before dispersing their seeds if you want them to reseed.
Zinnias still not your thing? In your garden, try them out for the following six reasons:
- With cultivars from the Dreamland Series, you can have a full-sized flower on a little plant. These zinnias are compact and dwarf, with stems that are 812 inches tall and totally double flowerheads that can be up to 4 inches across with a variety of colors.
- The dwarf, spreading cultivars of the Thumbelina Series have weather-resistant, solitary or semi-double flowerheads in a variety of hues. Their stems can reach a length of 6 inches, and their petals are 1-1/4″ wide.
- One of the largest and tallest of them all, the State Fair Series has huge, double flowerheads that measure 3 inches in diameter. Stems can reach a height of 30 inches.
- Typically, it takes zinnias 60 to 70 days from seed to flower (though it depends on conditions and variety). They are fantastic in a bunch of flowers!
- The tiny, narrow-leafed zinnias are great for hanging baskets and also make lovely dried flowers.
- Zinnias are considered to represent memories of those who have passed away. Discover more about the significance of flowers here.
- Zinnias may be harmed by bacterial wilt, powdery mildew, and bacterial and fungal spots. To prevent illness, keep leaves from getting too damp and correctly space your plants.
- Problems can also be brought on by caterpillars, mealybugs, and spider mites. Spraying should be avoided unless there is a real infestation because some leaf damage is not a problem.
- Thanks to their resistance to deer, zinnias may be able to prevent surrounding flowers from being eaten.
What benefits can zinnia flowers offer?
Zinnias appeal to pollinators. They are an excellent source of food for pollinators and bloom from May through October on average here in the Oklahoma garden. Many bees and butterflies that work hard in the garden producing food for humans are drawn to zinnias. Our garden is much more fruitful as a result.
Since they self-seed each year, zinnias are a need in the garden. The seed heads renew on their own after falling. I love that I can save money this way!
In any weather, zinnas are resilient. They can withstand both mild frost and intense heat. I merely fail to see a drawback to them.
Zinnias are a need in the garden because they provide an unparalleled explosion of color. Considering how little effort is required to maintain them, they are a genuine workhorse.
Do zinnias count as wild flowers?
Zinnias are among the simplest wildflowers to cultivate and bloom from mid-summer until the first frost, cheerfully bringing their vivid color to any sunny place. The more flowers you cut for bouquets, the more flowers your plants will produce. These well-liked annuals are deer resistant, long flowering, and incredibly productive. They attract monarch butterflies, which is the best part! All of the seed we sell at American Meadows is guaranteed to grow, non-GMO, and neonicotinoid-free.
When will zinnia flowers bloom?
Zinnia seeds can still be planted now for late summer color that will endure until the first frost. Additionally, they produce stunning cut flowers with a lengthy vase life.
Even the most inexperienced gardener should grow zinnias because they are one of the tried-and-true garden flowers. My first memories of gardening are when I first encountered zinnias. The bush beans and tomatoes set aside for zinnias were a constant source of conflict. My favorite annual flower is still the zinnia, and they now have a prime location next to my back deck where I can enjoy them in the warm weather.
Growing zinnias is simple; they prefer full sunlight and well-drained soil. They may be planted directly in the garden or transferred. Plant them in a peat pot that can be placed directly into the garden or planting bed if you decide to have a head start and want to transplant so as to avoid disturbing the roots.
There are many different types of zinnias. They come in sizes ranging from 6 inches to nearly 4 feet, from dwarf to enormous. The flower heads are available in many different forms, including single and double flowers, spidery shapes, and domes.
The amazing variety of hues is the best feature. The palest pastel hues to the brightest hues are all available in zinnias. They come in solid, multicolored, striped, and specked patterns.
Dead heading zinnias is advised by Michigan State University Extension to ensure flowering from early summer through frost. Zinnias are encouraged to continue performing by dead heading throughout the season. But because zinnias fatigue, I advise putting them in succession every two weeks. I intend to plant in succession beginning in late May and continuing until the first week of July, roughly. This ensures spectacular blooms through the end of September. It’s not too late to plant some zinnia seeds for color that will persist through the first frost in the late summer.
In addition to their amazing garden display, zinnias make fantastic cut flowers and may be used anywhere you need a splash of color. Many zinnia cultivars can stay in a vase for seven to twelve days. The mainstay of the farmer’s market is zinnias as well. Flower farmers would tell that zinnias are one of the most profitable flowers to grow due to their vibrant colors, ease of maintenance, and extended vase life.
The zinnia variants “Benary’s Giant” and “Cut and Come Again” are two of my favorites. Their surnames are biographical. On tall stems that stand between 40 and 52 inches in height, “Benary’s Giant” has huge blooms and dazzling flowers. Cutting the stem just above a bud junction will encourage “Cut and Come Again” to produce continuously throughout the growing season, as will all zinnias.
