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.
Do zinnias reproduce on their own?
Will Zinnias Self-Reseed? Here, the quick response is “yes” There is a fair possibility that zinnia seeds will germinate and thrive the following spring if the plants are allowed to blossom and set seed.
When the season is over, what should you do with zinnias?
Yes, zinnias regenerate after being cut. They make beautiful cut flowers that get better the more you cut them and preserve their beauty in the vase.
To keep your zinnias blooming throughout the entire season, you should deadhead them. To obtain two times as much enjoyment from your plants, either deadhead the blossoms as they begin to fade or take them off a little sooner and put them in a vase.
Pick stiff stems that are just starting to bud if you’re cutting for the vase.
What is the lifespan of zinnia plants?
The majority of zinnia types need 75 to 90 days to bloom after planting. Their “days to maturity” are defined as this period of time. However, other types, particularly dwarf varieties that don’t need to grow as tall before focusing on creating buds, are available that bloom in as little as 60 days.
For zinnias, the blooming period typically lasts two months. With some preparation, you may use succession sowing to extend that two-month window of flowers to four or more.
For as long as possible, succession sowing is essential to keep your garden blooming. If you’ve never heard of succession sowing, it is simply the process of sowing new seeds every two to four weeks to allow for the emergence of new plants at the same time that the older ones stop flowering.
How are zinnias prepared for winter?
Heirloom zinnias naturally reproduce, but you may do it yourself by preserving the seeds. This gives you the opportunity to start a fresh flower bed or add zinnias to a garden layout of your choice. The zinnia seeds from the toughest, most vibrant types should be saved. It is not advisable to save seeds from plants that are disease-prone, spindly, or fragile. Let the zinnias finish their life cycle and dry out. When petals have fallen off and the flower head has transformed into a seed pod, they are ready to be harvested. A tiny paper bag should be placed over the flower head. Alternatively, the flower head can be chopped and suspended in the bag upside down. The zinnia seeds land in the paper bag, which can subsequently be used to store them in an envelope that is clearly marked.
How are zinnias replenished each year?
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.

Do you remove zinnias in the autumn?
Once again, it’s that time of year when we must put those lovely gardens to bed; how quickly the time passes. There’s a lot to accomplish in the garden right now! To begin, consider the flower and garden beds:
Remove all the annuals and any other plants that won’t return the following year. Once they stop producing blooms, the plant needs to be removed by the roots and disposed of.
Perennials should be pruned, but I normally wait until the first frost. Inducing new growth that can be harmed by the frost if you prune the plant too soon. Do not compost any plants that were ill or had pests; instead, get rid of them! Once they are entirely gone and no longer producing visible leaves, trim them down to approximately 2 inches above soil level. Parsley is a biennial and will come back after a year. Rosemary is a beautiful herb that you can grow indoors in a pot and use all winter long. It’s time to make a ton of pesto, basil! (Recipe coming soon) Trim back your raspberry bushes so that every foot of your row has six of the strongest brown canes, then cover the strawberries with hay (or the salt marsh hay you used during the summer). Remove any dead or diseased cane from rose bushes, but avoid cutting the entire rose bush back. We do this in the spring, after the first frost, and mulch rose plants at the base with compost or leaves. Pull up tall canes or climbing tea roses with care, lay them flat on the ground, and then mulch them with leaves. Wait until they are dormant before pruning trees, shrubs, or other woody plants. Turning the soil in your gardens can help reduce pest issues the following spring. This fall, any undesired insect grubs or eggs will be broken up, brought to the surface, and fed to the birds.
Compost all waste that is free of illness. Utilize all of the plant components from this year’s garden to feed the one after it, as well as composted leaves and, of course, chicken dung! I toss my leftover pumpkins into the chicken coop after Halloween and add them to my compost pile. If your compost pile doesn’t have a lid, you might wish to cover it for the winter because this is when stray animals tend to enter your yard in search of delectable delicacies. If you’re anything like me, every type of animal that exists has shown up in my backyard (I believe they come because of the hens), but I don’t want to encourage them to stay.
Many inquiries this time of year regarding grass and leaves. The ideal time to plant grass seed is firstly in the fall. Lower temperatures in the fall, warm soil, sunshine, and more rainfall (we’re still waiting) all contribute to ideal growing conditions for grass. With your mower, shred the leaves to a height of 3 before removing the bag. It is ideal to shred when you can still make out part of the grass. Start at the edge of the grass and launch your leaves toward the center of the yard. Shredded leaves fall to the ground through the grass and break down by the following spring. Because winter rains and snow convert fluffy layers of leaves into dense, wet mats that can kill your grass by depriving it of oxygen and promoting disease, you shouldn’t leave a large pile of leaves on your lawn. It restricts air circulation and shuts out sunshine. Consequently, you must repeat this throughout the season. It’s nice to get outside and breathe in the clean air. Use leaves to cover garden beds, shrubs, and trees, especially if you have recently planted new plants. Your plants and shrubs will be vulnerable to winter burn and damage if we experience a winter without snow (which serves as a blanket for our plants) together with cold temperatures and strong winds. It is best to maintain the foundation plantings and garden beds appearing a little unkempt over the winter; the payoff in the spring will be worthwhile.
Empty out all outdoor containers, protect them from cracking, and store them upside down for the winter. Put all of your sprinkler nozzles and a bucket on a hook and hang it in the garage or shed. Before they freeze, store the hoses. Clean up all of your tools before putting them away. Take in all outdoor furniture and garden décor (apart from the chairs for the rinks in your backyard!).
Pumpkin festivals and autumnal celebrations:
10/19–10/20 Wellfleet Oyster Fest Two days of street celebrations featuring world-famous clams, oysters, and other shellfish. There are cooking classes, literary talks, tasting workshops, and visits of oyster grants.
On October 19th, Keene, New Hampshire, from noon until 9:30 p.m. Families take part in kid-friendly events like a costume parade, contests for eating pie and spitting seeds, live music, face painting, and the lighting up of 30,000 pumpkins.
This is a simple recipe for pesto that you can make in bulk and freeze for the winter. 1/4 cup pine nuts or walnuts, 1/2 cup freshly grated Romano or Parmesan cheese, 4 cups of basil, 1/2 cup olive oil, 2 cloves of garlic, 6 sprigs of parsley, salt and pepper to taste. Blend the basil, oil, garlic, parsley, salt, pepper, and nuts until the herbs are finely chopped. Add Romano or Parmesan cheese by stirring. Enjoy! Makes around 2 cups.
