based on the type. Some types are small, growing only 6 to 12 inches tall and wide, while others can reach heights of 4 feet and 1 to 2 feet.
Characteristics:
There are many different flower shapes that zinnias can take, including stars, daisies, dahlias, spiders, buttons, domes, and quill-leaf cacti. There are also singles, semi-doubles, and doubles within those shapes.
Do zinnias return each year?
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 kind of space do zinnias require?
The zinnia may be the best flower for indicating the start of summer. This annual that thrives in heat has vibrant, eye-catching spherical blossoms that provide color to any garden.
Cream, yellow, red, gold, orange, pink, rose, lavender, purple, plum, scarlet, white, and salmon are just a few of the many hues that zinnias may be found in. The bloom comes in a variety of sizes, from a few inches to three or four feet tall.
“May is a terrific month to plant zinnias,” said Gary Hayakawa, general manager of Fountain Valley’s Three Star Nursery, a wholesale producer whose plants are sold at numerous nurseries around Orange County.
Before the summer heat hits, zinnia roots have a chance to establish themselves in May, he said. ” They really take off once the weather warms up. In hot climates, zinnias thrive.
There are a lot of medium-sized types of zinnias in the nursery that grow 10 to 15 inches. The Pulcino, Dreamland, Dasher, and Peter Pan are a few popular medium-sized kinds.
Dwarf zinnias are also available; one example is Thumbelina mix, which blooms at 3 inches. State Fair and Dahlia-flowered are two tall kinds that reach heights of two to three feet.
Consider the following advice to successfully grow zinnias:
* Because zinnias are susceptible to fungus, choose a position with full light and no overhead sprinkler watering.
* Before planting, thoroughly amend the soil with homemade or bagged compost. Zinnias prefer a soil that drains well.
* Unless the plant is tall and unstable, plant zinnias at the depth they are in containers. Plant it a little lower than the current soil level in such instance.
* Give zinnias room to spread out so that air can circulate, which reduces the risk of fungus and leaf spot issues. Smaller kinds should be placed 6 inches apart from large types, and vice versa.
* After germination, transfer zinnia seeds into the ground or place them in tiny containers first.
About six seeds should be spaced evenly in a 4-inch pot for planting in containers. After they sprout, divide them into four plants. When they are about 2 inches tall, transplant them in the garden.
Work the soil well and amend before direct seeding. Then dig a shallow ditch with 3 to 4 inch high sides. When you irrigate, this will keep the water within. Place the seed exactly where you want the flowers to grow inside the ditch after leveling the soil there. Gently pat down the seeds after covering them with a quarter-inch of potting soil. Till the seeds sprout, mist the bed twice daily.
* To avoid fungus, water zinnias at ground level. Depending on the weather, water them deeply once or twice a week once they are 3 to 4 inches tall. Zinnias prefer slightly drier soil than most plants, but they are not drought-tolerant. It shouldn’t always be raining on the soil.
* Reduce irrigation if the month of June is cloudy. This will stop fungal illnesses. Once July’s warmer days arrive, fungal issues should go away.
Do zinnias prefer shade or the sun?
Light: Full sun is ideal for zinnia growth and flowering. Even in warmer climates with afternoon shadow, they can flower there, but they may be more prone to disease and produce fewer flowers.
Soil: Organically rich, fertile soils with good drainage are ideal for growing zinnias. Because zinnia seedlings are susceptible to rotting in cool, damp soils, having well-drained soil is crucial.
Plant zinnia seeds in rows or clusters spaced a few inches apart. Once the plant has four leaves, thin to 8 to 18 inches apart, depending on the variety.
Planting: Plant zinnias in the spring, just about the time you plant tomatoes, when all threat of frost has passed. Growing zinnias from seeds straight in the garden is simple. Start seeds inside four to six weeks before to your last frost date for earlier flowering.
Do zinnia flowers enlarge over time?
In the hopes that it will encourage you to plant some of these hardworking, heat-loving beauties in your garden this season, I thought I’d share some of my favorite types that we grow here on the farm.
To start with, we are incredibly excited about Unicorn Mix (pictured above). While it’s still a work in progress, this unique Floret blend has been a labor of love for us, and we’re pleased to be able to share it with the world at last.
The mixture features medium-sized, usually double blooms with eye-catching lavender centers that come in a beguiling array of vibrant sherbet shades, including raspberry, orange, magenta, lemon, apricot, dusty lilac, and blush.
Golden Hour, another new release from Floret, is a stunning assortment of warm buff, honey, and soft apricot flowers that began with two single plants we found in our fields.
We’ve gathered the seeds throughout time and picked out the lightest antique melon hues. Nothing else like it is available in the market. This cultivar is called after the golden hour just before the sun sets on the horizon, which is our favorite time of day on the farm.
The zinnia family’s largest-flowered kinds, Benary’s Giant Series plants frequently grow to a height of 4 to 5 feet (1.2 to 1.5 meters), and they frequently feature a high proportion of enormous double flowers. They have a total of 12 different hues and are renowned for having sturdy stems and exceptional disease resistance.
The ‘Giant Salmon Rose’ variety, shown above, is my all-time favorite since its warm peachy color is so adaptable and gets softer with age. Both pastel and vivid hues go nicely with it.
The “Desert Sunset Mix” (seen above) is another color I adore. It has my three favorite warm-toned Benary’s Giant hues: coral, orange, and carmine. When coupled with acid green or deep crimson blooms and foliage, they make a striking statement.
A longtime customer favorite, “Benary’s Giant Coral” is a glistening tropical coral-salmon variation. ‘Benary’s Giant Carmine’ (shown right) features raspberry-pink blooms that have a three-dimensional aspect as they age due to the outer tips of the petals fading.
The smallest tinge of lavender is bordered around the petal tips of “Benary’s Giant Orange,” giving them an iridescent appearance. ‘Benary’s Giant Lime’ has unusual Granny Smith apple-green flowers that are densely covered in petals.
‘Benary’s Giant Deep Red’ (shown left) has a deep ruby-red color with just a tinge of purple on the back of the petals, giving them a dazzling, iridescent appearance. ‘Benary’s Giant Bright Pink’s’ (right) cotton candy-pink blossoms are as delicious as they come.
The dramatic, deep wine shade “Benary’s Giant Wine” (seen on the left) is a customer favorite. The outer petals of “Benary’s Giant Lilac” (shown on the right) begin as a vibrant lilac and gradually turn a chilly, pale lavender, creating a haunting image.
The most prolific and floriferous zinnias I’ve ever grown are the Oklahoma Series. Oklahoma Salmon, Pink, Carmine, Ivory, White, Yellow, and Scarlet are among the series’ seven colors.
‘Oklahoma Salmon’ (seen above) features small, double blooms that go beautifully with everything. They are a warm blend of salmon and peach. Everyone adores this find!
To the satisfaction of innumerable growers and designers, Frank Morton from Wild Garden Seed in the Pacific Northwest brought back “Oklahoma Ivory,” which had previously been withdrawn. This cultivar, cherished for its adaptable creamy ivory color and lovely double flowers, is one that we are thrilled to offer.
The Queen Series of zinnias has the most distinctive collection of uncommon colors, such as lime green, smoky apricot, dusty rose, and limey blush.
A welcome advance to the zinnia family, the Queen Series cultivates vigorous plants with strong stems and hardy flowers in addition to their distinctive colors.
The ‘Queen Lime Blush’ flower, which is usually double and semidouble and is shown above, is unlike anything else we’ve ever seen. Everyone who sees them falls in love at first sight. It must be grown!
“Queen Lime Orange”: The most exquisite assortment of iridescent raspberry, apricot, and smoky peach with a dark cranberry center can be found in the Queen Series. When paired with lush greenery and blooms, this color’s versatility looks amazing.
Types with scabiosa flowers: I cultivated scabiosa-flowered zinnias for the first time in 2014, and they rapidly rose to the top of my list of seasonal favorites. The lacy double blossoms resemble double-flowered echinacea or little gerbera daisies.
They feature lovely long stems, strong disease resistance, and a gorgeous variety of hues.
The improved variety “Candy Mix” (seen above) features a higher proportion of double blossoms in a cozy, upbeat combination of scarlet, raspberry, pink, salmon, tangerine, gold, and cream.
It’s important to note that many growers in warmer areas have observed that they don’t receive the same high proportion of doubles with scabiosa kinds (doubles shown on the right) that we experience in the Pacific Northwest.
I believe that if plants experience any stress, such as not getting enough water or being exposed to too-high temperatures, they will begin to produce single blooms after doing a lot of research and exchanging letters with the breeders (pictured left).
Although the single blooms are attractive and distinctive, many people have been let down by this fact.
The frilly double blooms of “Zinderella Peach” (seen above) have a dramatic dark center and are a warm blend of salmon, peach, and cream. This may be my favorite zinnia out of all the ones we cultivate. The exquisite blend of blush and delicate lavender known as “Zinderella Lilac” (seen above) is highlighted with an eye-catching black center. Floral designers adore it since it’s perfect for wedding work!
Bicolor novelties: Everyone who sees these interesting bicolor novelties is bound to be intrigued.
Since we’ve been cultivating “Macarenia” for years, we’ve discovered that people either adore it or despise it. For a whimsical twist, each glistening crimson flower has a gold tip. This diligent plant, which took home the Fleuroselect Novelty Award in 2012, does well in the heat and is quite simple to grow.
With a fresh spin on zinnias, “Mazurkia” is a Fleuroselect Winner with good cause. A lively, campy double blossom with lipstick-pink centers and gentle blush tips is produced by the medium-sized plant.
Types with tiny flowers: The traditional “Lilliput Mix” (seen above) belongs in every cutting garden. The simple-to-grow, heat-loving plants bear an abundant crop of pleasant blooms in hues of rose, carmine, orange, coral, white, yellow, and violet on long, sturdy stems. They are perfect for floral arrangements because of their small flower size.
I adore “Lilliput Salmon” in particular (pictured growing above). All summer long, this delightful bloomer produces a profusion of small, completely double, salmon dome-shaped flowers.
The Sunbow Series has been around for a very long time and is available from Johnny’s Selected Seeds. It features tiny 1- to 2-inch (2.5 to 5 cm) double blooms that are supported by long, robust stems. It is available in a bright assortment of colors, including white, red, orange, pink, scarlet, and golden yellow. Plants are perfect for flower arrangements since they have long, wiry stalks.
Cactus-flowered varieties: These amusing novelty flowers come in a variety of hues, including orange, pink, red, yellow, peach, and white, and have the coolest twisted, shaggy petals.
My favorite variety is “Seora” (seen above), which has warm salmon-apricot quilled blossoms and yields an abundance of big flowers with sturdy stems. It must be grown!
Mexican zinnias: Although the plants themselves are small, from July to early fall, they produce an abundance of stems for cutting. They are more like a bedding plant than a cropping variety due to their small stature, but I believe they belong in every cutting garden.
The charming gold, cranberry, orange, and cream flowers in the “Persian Carpet Mix” (seen above) work well with these colors.
A wide variety of small bicolor flowers in the vivid, eye-catching “Aztec Sunset” combination come in tones of buttercream, gold, crimson, rust, and merlot. These dependable bloomers are a wonderful complement to the flower border’s front and the cutting garden.
