Annual plants known as zinnias produce stunning flowers with vibrant hues like red, pink, yellow, and purple. The flowers, which have layered petals, are traditional picks for the cutting garden.
Zinnias can grow as tall as three feet or as short as six inches. They can be purchased as little plants at the garden center or grown from seeds, both of which are quite simple. In South Florida, they can be planted in the fall as well as the spring throughout the state of Florida.
Full light and well-drained soil are essential for zinnias. Getting rid of the old blooms will prolong flowering.
Grow zinnias for homemade bouquets or use them in a mass planting, container, or border!

In Florida, how long do zinnias bloom?
It is simple to grow zinnias from seeds. Though not impossible, transplanting zinnias is difficult for them. Personally, I advise planting them immediately where you intend to grow them from seed. If the correct circumstances are present, they will develop quite quickly from seed.
Because zinnias are annual plants, they only bloom for one season. Planting zinnias is not particularly difficult. They demand the least amount of upkeep and care. They are tolerant plants that do well in warm, dry climates. Seeds for zinnias should be planted after your last frost because they do not fare well in chilly climates. See the frost dates for your hardiness zone.
These blooms prefer soil that drains well, has a pH that is somewhat acidic, and receives direct sunlight. The recommended seed depth is 1/4 inch, and the recommended seed spacing is 6 to 12 inches. The germination of seeds takes 4–7 days.
Can you grow zinnias in Florida?
Zinnias are annual plants with lovely flowers that come in vibrant colors like red, pink, yellow, and purple. They are an old favorite that thrives in Florida gardens. In fact, all colors besides blue are available for this flower that enjoys the heat.
Do zinnias thrive in hot climates?
Can you recommend an annual bedding plant that is quick to grow from nursery packets, easy to grow, and can provide me with a lot of color throughout the summer heat?
A. The zinnia, in my opinion, would work nicely for you. There are a wide variety of zinnia flower varieties, sizes, and colors available. There are kinds that grow to less than a foot tall, others that top 2 feet tall, and every height in between.
You can choose from blossoms that are less than 2 inches across to 5 inches across and are appropriate for cutting. Flowers are available in single colors or bicolors. The plants cover themselves in vivid, multicolored blossoms regardless of size.
You must give your garden proper care if you want to be sure that your plants are growing and blooming at their best. Regularly water and fertilize your plants, but don’t overdo it. Also, remove wasted blossoms as soon as possible to stop seeds from sprouting. Avoid getting the leaves wet, especially late in the day, as some zinnia cultivars are prone to mildew.
The nicest part about zinnias is that they don’t draw insects, and they survive full sun and hot temperatures quite well. The large and manageable zinnia seeds are ideal if you’re not in a rush. Zinnia seeds sown directly into the garden germinate fairly quickly in our moderate environment. Growing plants from seed is a quick and affordable approach to get lots of plants for a low cost.
Q. All the flowers in my border are being destroyed by earwigs. Even some of the roses I cut have earwigs living inside of them. What can I do to control them?
A pair of posterior pincers are present on the thin, brown earwig, which is around an inch long. Although they are typically not a problematic pest in the garden, if their population increases significantly, they can do significant harm by eating holes in leaves and blossoms.
They spend the day hiding in damp, dark locations and emerge to feed at night. This layout makes it possible to frequently regulate them by scattering loosely wrapped newspapers throughout the garden. The newspaper, which can be thrown out every day or two, will become home to the earwigs.
Are zinnias indigenous to Florida?
Wild zinnia, also known as prairie zinnia or Rocky Mountain zinnia, is a perennial groundcover that forms a mound and rises 4 to 8 inches high. From mid-summer till frost, the plants are covered in papery yellow blossoms. It prefers hot, sunny places with well-drained soil and does well in rough terrain.
True American natives, zinnias can be found in Mexico, Central America, and the Southwest of the United States. The best-known annual plant is the common zinnia (Zinnia elegans), from which plant breeders have developed an amazing variety of cultivars. There are roughly 17 different species of annuals and perennials.
The wild zinnia is becoming more popular as a garden plant, and it can now be found on a number of lists of Western gardeners’ preferred water-wise plants. The scientific name of the plant, Zinnia grandiflora, will take you to a number of sources for plants and seeds online. Once planted, it becomes a hardy spreading perennial, but until the heat of early summer arrives, it won’t emerge from hibernation or begin to develop.
Do zinnias reseed 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.
Are zinnias sun-sensitive?
It’s hot outside, so gardening in the summer calls for plants that are minimal care, drought and heat tolerant, and have vibrant colors.
The better, the brighter.
On each of the three criteria, zinnias were suitable. plus more. They’re among the best flowers that savvy gardeners may use in their gardens, in fact.
If there is a flower that is simpler to grow, please let us know. Since zinnias are annuals, their life cycle from seed to flower to seed is short. Simple garden preparation is all that is needed for zinnias’ arrow-like, pointy seeds to germinate. Simply place them in soil that is well-drained, in full sun, and in an area that receives a lot of summer heat, and you’ll soon see small seedlings and blooming flowers. No enduring can boast of that speed!
One gardening buddy just scatters seeds wherever she wants a few zinnias, watered those areas for a few days, and then lets the zinnias’ naturally easy-to-grow nature take its course.
“Candy Cane,” “Green Envy,” “Persian Carpet,” and “Pop Art.” When a variety has names like those, color is guaranteed. The ridiculous color palette of zinnias includes every vivid and pastel shade (aside from blue), as well as bi-, tri-, and crazy-quilt combinations made for cutting, luring pollinators, etc.
Many new zinnia series give options for height and width in addition to vibrant color.
- While Zinnia elegans tall varieties continue to be the preferred option for the back of the border, shorter series are now challenging the low ground once held by marigolds and petunias. The Thumbelina Series of dwarf zinnias reach their highest point at 6 to 8 inches, whereas the Magellan Series remain roughly knee high at 14 inches.
- The Crystal Series and other creeping or spreading Zinnia angustifolia are a revelation for the front of the border, raised beds, containers, and even ground coverings. The fact that its native to Mexico is even more drought tolerant than regular zinnias makes it the preferred choice for hot locations like sidewalk beds or that no-man’s-land next to the garage.
- With a height of about 8 to 12 inches, ZaharaTM zinnias are renowned for their resistance to powdery mildew and leaf spot (see below). In the entry beds of the Regenstein Fruit & Vegetable Garden, we paired Zahara Yellow, which is brief but sweet, with tiny sunflowers.
Zinnias are obviously meant for the vase because they have style and long, sturdy stems.
The words stars and daisies, dahlias and spiders, buttons and domes, and quill-leaf cactus are all used to describe zinnia blooms. Flowers come in different varieties: “singles,” which have their petals arranged in a row around an open center; semi-doubles; and doubles. Each one is fantastic in floral arrangements.
The best zinnias for cutting are, of course, the tall kinds; “Benary’s Giant” is renowned for its three-foot-tall, robust stems and huge flowers. Just above a bud joint, angle-cut zinnia stems. Zinnias often stay a long time in a vase; thus, remove all but the most obvious leaves off the stems before placing them in water.
Zinnias require little upkeep. Because they grow quickly, they shade out weeds. They don’t need mulching, and the only fertilizer they need is an occasional application of a well-balanced mix.
Deadheading encourages the growth of additional blooms. Lack of time to deadhead? When it comes to a big bed, the Zaharas indicated in the sidebard are a significant time saver.
The Profusion Series, a cross between Z. elegans and Z. angustifolia, is resistant to powdery mildew, which is the bane of zinnias, just like Zaharas.
Zinnias are accustomed to dry environments because they are indigenous to the grasslands of the southwestern United States, Mexico, and South America. However, wet summers, like the one we’ve had so far, can be damaging. And leaf spot and powdery mildew can result from that. Three recommendations for surviving inclement weather:
- Only water as necessary, and then only at the plant’s base. Wet leaves can encourage the growth of mildew, and water splashing can instantly spread fungus from the ground onto zinnia leaves.
- Taller, mildew-prone kinds can be hidden by foreground plants.
- As one horticultural put it, “Even when zinnias are coated in powdery mildew, they’re covered with flowers,” do both #1 and #2 and accept that zinnia leaves (but not flowers) are impacted by wet weather.
Zinnia seeds can be saved with ease. Simply let the blossoms to completely dry on the stalk, gather the seedheads, and delicately crush them in your fingers to release the harvest of seeds for the following year. In the same manner as other seeds, store in a cool, dry area. (And save some for our seed swap in February of next year in a labeled envelope!)
Last but not least, zinnias attract butterflies, so plant them every year. The plants with larger flowers serve as landing places for butterflies looking for nectar. (The same is true with hummingbirds.) To capture the most attention, try tall zinnias with scarlet or hot pink blossoms.
