Grow Great Zinnias

Written by
Floret

Nothing says summer more than an armload of cheerful zinnias. Available in a brilliant rainbow of colors, these happy blooms are a must grow for any flower lover.

As one of the easiest cut flowers to cultivate, they are a perfect first crop for beginning growers and are reliable, prolific producers for most flower farms.  

We’ve been growing zinnias since the beginning and every year I fall more and more in love with them.

Field of zinnias at Floret Flower FarmZinnias resent cold weather and prefer to be planted after things have warmed up a bit. Many gardeners in warmer parts of the world are able to successfully direct seed their zinnias straight into the field, but here in cool Washington we start our plants in 72 cell trays in the greenhouse 4-6 weeks before our last spring frost.

zinnias germinating in cell traysPlants are tucked into the field around mid-May, once the weather has sufficiently warmed up and all danger of frost has passed. Like every flower grown on our farm, we try to give them the best start possible. Learn more about soil preparation here.

Once the planting beds have been prepared, we lay down four lines of drip irrigation, roughly a foot apart and then the beds are covered with a layer of pre-burned landscape fabric to control weeds. Plants are spaced 9×9 inches apart with five rows per bed. 

Field of zinnias at Floret Flower FarmIf given good soil and a steady supply of water, plants can get huge and require some type of support. We use a layer of Hortonova netting stretched horizontally about 12 inches above the ground. Netting is held by in place by metal hoops that we made with our Johnny’s Quick Hoops BenderAny type of stake, wooden or metal, will work just fine. As the plants grow, they push up through the grid of netting and get the support they need.

Field of zinnias at Floret Flower FarmZinnias like the heat and it’s important that they are grown in full sun. In addition to choosing a sunny spot, I always grow them in fabric for the added heat.  

When we first started growing zinnias this closely together I was worried that they would be plagued by disease, but since they are grown in such rich soil, this hasn’t been a problem. We succession sow zinnias every 2-3 weeks in order to have a steady stream of these beautiful blooms all summer long. 

pinching The secret to getting the longest stems from your zinnias is pinching them when they are young. Here’s how it’s done: When plants are between 8 to 12 inches tall, take sharp pruners and snip the top 3 to 4 inches off of the plant, just above a set of leaves. This signals the plant to send up multiple stems from below where the cut was made, resulting in more abundant flower production as well as longer stem length. The photo above demonstrates pinching with another type of plant. 

Field of zinnias at Floret Flower FarmIf you are not regularly harvesting your zinnias, be sure to deadhead any spent blooms to help focus the plant’s energy into producing new flowers and not going to seed.

Zinnias need to be picked when they are fully ripe, otherwise they won’t last in the vase. To tell whether a zinnia is ready to harvest use the “wiggle test.” Simply grab the stem about 8 inches down from the flower head and gently shake it. If the stem is droopy or bends, it is not ready to cut. If the stem is stiff and remains erect, it is ready to harvest.

Zinnias are considered a “dirty flower” and benefit from a drop of two of bleach in their water. Do not put them in the cooler since the flowers are very cold sensitive.

Depending on what your needs are, there is definitely a zinnia for you.

I thought I’d share some of my favorite varieties that we grow here on the farm in hopes that it inspires you to plant some of these hardworking, heat loving beauties in your garden this season.

armload of salmon coral colored zinnias salmon coral colored zinniasBenary’s Giant Series: The largest flowered varieties in the zinnia family, plants often reach 4-5 feet tall and have a high percentage of huge double flowers. They come in a wide range of colors (12 in total) and are known for their strong stems and good disease resistance.

My all time favorite variety is Giant Salmon Rose (pictured above) because its warm peachy color is so versatile and softens with age. It pairs well with both pastel and vibrant colors.

field of zinniasI also love the Desert Sunset Mix (pictured above) which includes my favorite warm toned Benary’s Giant colors: Coral, Orange and Carmine. They make a bold statement when combined with acid green or deep maroon flowers and foliage.

If you’re looking for individual colors, Johnny’s Selected Seeds carries the full range.

coral and salmon zinniasOklahoma Series: These are hands down, the most productive and floriferous zinnias I’ve ever grown. The series boasts 7 colors including Oklahoma Salmon, Pink, Carmine, Ivory, White, Yellow and Scarlet. Ivory was recently discontinued but we are working on building up our stock seed to hopefully reintroduce it in the near future.

Salmon (pictured above) has petite, double blooms that are a warm mix of salmon and peach and combine well with anything. Everyone loves this treasure! 

Queen series of zinniasQueen Series:  Unlike other zinnias, this series includes the most unique array of unusual coloring including lime green, smokey apricot, dusty rose and limey blush.

In addition to their special coloring, the Queen Series also produces vigorous plants with sturdy stems and tough flowers, a welcomed improvement to the zinnia family.

These gorgeous novelties are sought out by designers for their unique coloring.

Queen Lime Blush ZinniasThe mostly double and semi double flowers of Queen Lime Blush (pictured above) are a stunning blend of green and purple, unlike anything we’ve seen.

Everyone who sees them instantly falls in love. It’s a must grow!

queen lime orange zinniasQueen Lime Orange: This exciting new addition to the Queen Series is the most beautiful range of iridescent raspberry, apricot and smokey-peach with a dark cranberry center.

This versatile color looks incredible when combined with rich foliage and blooms.

scabiosa zinniasScabiosa Flowered types: I grew scabiosa flowered zinnias for the first time in 2014 and they quickly became one of my favorite crops of the season. The frilly double blooms look like mini gerbera daisies or double flowered echinacea.

They have nice long stems, good disease resistance and come in a beautiful range of colors.

armload of scabiosa zinniasCandy Mix (pictured above) is an improved mix that contains a higher percentage of double flowers in a warm, cheerful blend of scarlet, raspberry, rose, salmon, tangerine, gold and cream.

scabiosa zinniasOne thing to note is that many growers in warmer climates have noticed that they don’t get the same high percentage of double “scabiosa types” (pictured right) that we do here in the Northwest.

After a lot of research and emails back and forth with the breeders, it seems that if plants undergo any stress, including not getting enough water or too high of temps, they will start producing single flowers (pictured left).

While the single blooms are pretty and unique, many folks have been disappointed by this fact.

zinderella peachZinderella Peach has frilly double blooms that are a warm mix of salmon, peach and cream, accented by a striking dark center.

Of all the zinnias we grow, this might be my favorite.
zinderella zinniazinderella zinnia Zinderella Lilac (pictured above) is a lovely mix of blush and soft lavender, accented by a striking dark center.

It’s ideal for wedding work and floral designers love it!

bicolor zinniaBicolor Novelties: These unique bi-color novelties are sure to catch the attention of everyone who sees them.

We’ve been growing Macarenia for years and have found that people either love it or hate it. Each glowing scarlet petal is tipped in gold for a fun twist. Winner of the Fleuroselect Novelty Award in 2012, this hardworking plant thrives in heat and is very easy to grow.

mazurkia zinniaMazurkia brings a new twist to zinnias and is a Fleuroselect Winner for good reason. The mid-sized plant produces fun, campy double flowers with lipstick pink centers and soft blush tips.

armload of zinnias Miniature flowered types: The old fashioned Lilliput Mix (pictured above) deserves a spot in every cutting garden. The easy to grow, heat loving plants produce a bumper crop of sweet blooms on long, strong stems in shades of rose, carmine, orange, coral, white, yellow and violet. Their petite flower size makes them ideal for flower arranging.

zinnias in flower fieldI especially love Lilliput Salmon (pictured growing above). This adorable bloomer produces an abundance of petite, fully double, dome-shaped salmon flowers all summer long.

zinniasThe Sunbow Series, available from Johnny’s Selected Seeds has been around for ages and has miniature 1-2” double blooms that ride atop long, sturdy stems. It comes in a cheery mix including: rose, purple, golden yellow, scarlet, orange, pink and white. Plants have long, wiry stems that make them well suited for flower arranging. 

cactus zinniasCactus flowered types: These fun novelties have the coolest twisted, shaggy petals and come in a wide range of colors including orange, pink, red, yellow, peach and white.

My favorite is Señora (pictured above) which has warm salmon-apricot, quilled blooms and produces a bumper crop of large flowers that have long, strong stems. It’s a must grow!

Mexican zinniasfield of zinnias at Floret Flower Farm Mexican Zinnias: While plants themselves are compact, they churn out an abundant amount of stems for cutting from midsummer to early autumn. Their petite stature resemble more of a bedding plant than a cropping variety but I think they are deserving of a spot in every cutting garden.

The Persian Carpet Mix (pictured above) includes adorable gold, cranberry, orange and cream flowers.

Aztec sunset zinniasThe brilliant, eye-catching Aztec Sunset mix includes a wide range of miniature bi-color blooms in shades of buttercream, gold, cranberry, rust and merlot.

These reliable bloomers are a great addition to the cutting garden and front of the flower border.

    I just wanted to come back to thank you for this post. Zinnias were my grandmother’s favorite flower. But I have never had much success with them. After reading the post and seeing all the beautiful varieties, I was inspired to try again. So I turned my raised garden bed where I normally grow tomatoes into a zinnia patch this year. I planted a few too many seeds really because I wanted to be sure to get some. Well, I did! The entire bed is just full of all types of beautiful, colorful zinnias just like my grandma loved. My personal favorite are the chartreuse green ones. But it’s hard not to love them all! Thank you again for just the push I needed!

    Hi there!
    I have been gleaning every tidbit of wisdom you have to share from your site as well as your book as I start my flower farming journey. I’m hoping you can clarify something for me. You recommend Floralife to aid in vase longevity for most flowers. Should I use it for Zinnias as well? Or just the bleach added to the water?
    Thank you so much.

    Hi there,

    I am growing zinnia in containers on my patio for the first time. I bought them as healthy plug plants and pinched them when they go to a decent height to encourage more leaf growth.

    We have reently had floods, then high winds and now a day of 32° heat. As a consequence one of the plants has completely collapsed. The stem is too weak to hold the plant up. I have tried staking to hold it up, but it no looks dry like its dying. How can I fix this. Or is there no hope.

    I have planted many varieties this year. The whimsical colors and shapes just make me smile. I lost all first 2 rounds to rain. The flowers growing now are coming along well. They are not quite big enough to pinch, but I am very hopeful they will produce well. I love your blogs!! The knowledge I am gaining is awesome. I keep your book handy indoors, but if out in garden, I look up your blogs with my phone.

    I planted a verity of zinnias in large pots, to my surprise they turned out beautiful. The only problem I had was they got to large at late season but still beautiful, This year I am doing the same thing. This time I will cut them back shorter and see what happens. Some of my friends liked them so much in pots, they are doing the same thing.

    My husbands mom gave us a cheap packet of zinnia seeds last year to plant in the courtyard of our (first and new) home. I was so surprised at how well they did with so little care! Those little flowers really started a love of gardening in me! This post is so helpful to know how to better care for them this year!

    I’m trying Zinnia’s from seed this year – Zowie Yellow Flame from Johnny’s and seeds I harvested from a friend’s zinnia bed last fall. The Zowie are growing well and about 3″ tall – the other are half that height and I’ve only had 2 to come up for some reason…should I be taking the flat in at night? I have been so far.

    This is so helpful! I have gardened all of my life, but I have always focused on vegetables and companion flowers like marigolds and nasturtiums. I’ve never grown zinnias before, but I just started a flat of the Queen Series today. I’m excited to see how they do in my garden this year. Thank you for taking the time to put all of this information together to help aspiring flower growers like myself. It truly is appreciated.

    A dirty flower is one that will dirty up the water quickly – sunflowers and zinnia are examples of this. Adding a bit of bleach or hydrogen peroxide to the water keeps the water cleaner longer with ‘dirty flowers’. :)

    So thankful to hear that zinnias like the heat! I also raise dahlias and have one particular bed that is up against a barn wall and east facing. It gets extremely warm with heat reflecting off the barn and the dahlias did not like it even with twice daily watering. Have a bunch of seeds started in the greenhouse now. Hopefully they’ll like this location better. First time growing these. Thanks for the great info

    hi, I’m stating this year to be a flower farmer! So excited! I live in Cincinnati Ohio. Actually, in a small rural town outside of Miami University.

    We are starting small with a 1/2 an acre and building from there. Where would you recommend we purchase the zinnias from? They are my favorite. If you had to advise us on 5 to plant, which five would you suggest?

    Any other advise would be great. We are really reading up on all of it. I just love your flowers! It inspires me. We are going to prepare our soil and I think we are going to plant seeds unless you think otherwise. What about water? How do you get water to your flowers?

    They are so carefree in our east Texas sandy loam that I use Zinnias as row markers in the orchard. Just scattering a handful of seeds adds a splash of color to the end caps or paint the orchard with dabs of color beneath the olive trees. It is a joy to see the pollinators flitting between Zinnia islands.

    Love all the variety and pics! Thanks for sharing! I’m considering starting zombie from seed instead of direct sowing. Would they do well in a sunny window sill, or do I need to use grow lights? Do you recommend a heat mat? Thanks!

      Hi Tiffany,

      Zinnias are so easy you can direct sow them, or start them inside under lights or in a southern facing window. In a window they can tend to get leggy, but if you plant them outside fairly quickly, or take them out to get sunshine during the day, they should do really well for you.

    I’m in New Zealand on the east coast of the North Island. Its a temperate climate with hot dry summers. Zinnas are a favourite to grow in bulk in my gardens but unfortunately the fabulous range shown aren’t so available here. Shame!

  28. Cindy on

    I’m in one of the milder parts of Montana (Zone 3+ or 4-), but I’ve struggled starting them in the greenhouse and had the best luck direct sowing once it warms up. A surprise frost comes late often enough that I usually wait until last week of May, meaning it’s quite a wait before blooms.

    I love Magellan because it is so beautiful in arrangements with cool colors (not quite pink) and warm colors (not quite salmon) while staying bright and vivid. For weddings, Polar Giant is my go-to.

    Zinnias seem to love the hot and dry summer climate up here in the northern Cariboo region of British Columbia. They tend to seed and transplant so easily…and even tolerate a tiny bit of neglect. This will be my first year growing for actual cut flower sales so I went a bit wild with choosing zinnia varieties thanks to your numerous must-grow recommendations and amazing photos! The more I look at the options on this website and seed catalogues I keep thinking I should add just one more type…

    Zinnias are my favorite cutting flower mainly because they are so easy to grow and they’re very prolific. The Queen Lime series are my favorites because their colors are so unusual.

    We love growing Zinnias here in South Florida. It is sometimes difficult to get the variety and color of flowers down here in the tropics, and zinnias help fill that void. I am excited to try this trick to get longer stemmed flowers. And to provide additional nutrients through weekly seaweed tea.
    We do have a major issue down here in the south with Powdery Mildew, its so humid it has become a never-ending battle. Perhaps with the additional seaweed tea nutrients and healthier plants, I can battle this a little better. Now just to keep the iguanas out of the flower beds (the eat everything to the ground and outsmart even chicken wire)… but another south Florida issue.

    I’m so glad you mentioned that Scabiosa varieties revert to single flowers under stress. Last year I was so excited to grow Zinderella Peach for the first time and was so disappointed with the results. Not only were they single flowers, but most of the flowers didn’t even have a complete circle of petals; many only had 4 to 6 odd petals per flower and were a washed out dirty white color on otherwise healthy plants. My other varieties of zinnias were beautiful, so I couldn’t figure out what the problem was. Here in Eastern Washington are summers are so hot, I think, sadly, I won’t try to grow this variety again. Thank you for that valuable bit of info.

Sometimes when a perennnial is done blooming for the season in spring I will throw in a pack of zinnias for color the rest of the summer and have had a lot of success with that.

    Zinnias are a favorite of mine and I plant them every year. We recently moved to a house with a smaller yard and so I have less space to plant in. I will definitely be using the pinching technique to encourage more blooms. I’d love to try the Oklahoma series, as that’s where I live. :) Maybe next year!

    Whoa- they revert to singles in stress? I thought they loved heat! This explains why my “green envy” zinnias reverted to a pale yellow single petaled flower last year? I planted them in full sun (that’s 13+ hours of South Carolina heat, which I thought they could handle)
    I will experiment with part shade this year to see if it makes a difference. Green Envy is not a Scabiosa type but maybe it’s the same issue…

So stunning and the sizes ranger from 2″ to nearly 4″ wide. I am in love with these, along with the dwarf series, Profusion Coral Pink, Fire, and Orange.

    I ordered your ‘Cut Flower Garden’ book and LOVE it! I’m hoping to grow the table flowers for my son’s September wedding. I’ve always grown a few flowers, but not for a special occasion. Living in the Flint Hills of Kansas, we knew zinnias would be top of the list, as we tend to have very hot windy summers. I had no idea there were so many beautiful varieties until reading your blog and looking through your book. I’m looking forward to reading all the tips because I know I’m going to need help! Thanks so much for writing such a beautiful, helpful book!

    It is absolutely pouring here in the UK so this article was a magic pick me up. I have sent it to a sick friend who loves her garden. Roll on summer and thank you for all the advice.

    Thank you for the explanation about why double zinnias can sometimes turn into scruffy single zinnias! I had been wondering why that was and will try a slightly coler spot for them next season

    I am growing an annual cutting garden for the first time this year. I usually stick to perennials, roses, fruits and vegetables. But, I fell in love with the Zinderella zinnias this year….and now I can’t stop purchasing all kinds of zinnia seeds! Thank you for the great tips on how to grow these amazing hearty flowers! I am thrilled to hear that they grow so well here in Western Washington. I can’t wait to start them… keep up the good work :)

    Zinnias have been in the family garden every year since before my dad was born. There are multiple pictures of my grandmother’s garden bursting with zinnias from back in the day, and my father has been growing from saved seed for years now. They have the coolest antique cream colored single petaled cactus flowered variety that pops up every year. ( I’m going to try to save from it this year. (I cut them all this year.. oops) I named my daughter Zinnia Raine in memory of my late grandmother and we grow tons every year! I’m especially excited to try the zinderella series and the queen lime blush this year !

    I love Zinnias. We had a hot summer (for us) last year and the Zinnias loved it. The Queen and Bennary series have been brilliant. I am growing the Zindarellas this year for the first time and I can’t wait! Thank you for this really thorough exploration of varieties on offer!

    Zinnias are one of the flower types we grow the most of each summer. They are extremely easy to grow. We direct sow a few times through the summer, but just one planting provides us with blooms for many weeks. Definitely a must-grow!

    I used to be a huge zinnia snob, feeling like they were second class to dahlias, but now I’m a total convert. I have too many seed variety for my garden space, so I’m trying to convince my husband to let me dig up some of our existing landscaping; we’ll see how that goes. Anyways, this year I’m really excited to grow a few new (to me) varieties I bought from a different seed company: Uproar Rose and Art Deco. Thanks for the tips about scabiosa varieties! I’m going to pass that info on!

    I am so glad to have read this article! Zinnias have been a major part of my cutting garden for years and they are one of my favorite things to grow. I love the look of the scabiosa zinnias but haven’t had as much success with them as I would like, it’s good to know that it’s stress that’s causing the single blooms! I’ll be a little more careful with those this year :) Thanks for all the amazing blog posts!
