7 Best Easy Annual Flowers to Grow In Any Zone (With Photos)

By Deanna Talerico Feb. 3rd, 2026
/

Here are 7 of the best annual flowers to grow in any zone, including my top favorites to plant in our garden every year! This guide will cover key growing tips, benefits, uses, and our go-to varieties of each one.

Every flower on this list is low-maintenance, easy to grow from seed, and does well in containers. They all make excellent companion flowers in a vegetable garden – attracting pollinators, birds, and other beneficial insects. Plus, flowers bring a delightful pop of color, beauty, and whimsy to any garden space!

If you don’t want to start from seed, you should be able to find most of these flowers at your local nursery in the spring too.

What Are Annual Flowers?


Annual flowers complete their entire life cycle – from seed to flower and back to seed – in one growing season. The original plants won’t continue to grow or come back the following year, though some may self-seed to produce new plants (aka volunteers). Therefore, annual flowers must be replanted each spring in most climates. 

All the flowers on this list are most commonly grown as annuals, though a few can persist as short-lived perennials in warmer, frost-free zones (9-11) including nasturtiums and calendula.

Starting Annual Flowers from Seed


Each flower on this list can either be started from seed indoors, or directly sown outside in spring once the risk of frost has passed. We start most of our annual flowers indoors to get a jump start on the growing season, which means more blooms and color in the garden sooner!

To start indoors, sow flower seeds in containers of fluffy seed-starting mix about 5 to 6 weeks before the last spring frost date in your zone. Use a seedling heat mat to help encourage quick germination, keep the soil evenly damp but not soggy, and provide ample bright light (e.g. a grow light) to prevent them from getting leggy. See our complete guide on starting seeds indoors for more detailed tips.

You can transplant seedlings outside once the risk of frost has passed, but be sure to harden off indoor seedlings first to prevent transplant shock! I like to tuck annual flowers into almost every corner of our DIY raised garden beds, and between vegetable plants where there is space.

1) Calendula ~ Calendula officinalis


Cheerful and daisy-like, calendula is one of the best all-around annual flowers to grow. It’s beautiful, boasts a long blooming season, and has SO many wonderful uses. Calendula is especially renown for its ability to soothe skin issues.

Calendula is sometimes referred to as “pot marigold” but don’t accidentally confuse it with true marigolds, such as french marigolds. Marigolds are on this list too, but are distinctly different and not nearly as medicinal in nature.

Some of our favorite calendula varieties include: Resina, Pacific Beauty, Strawberry Blonde, Pink Surprise, Oopsy Daisy and Zeolights.

Benefits of Calendula


  • Calendula flowers attract bees and butterflies while repelling pest insects.

  • Calendula is a highly medicinal and edible herb with many wonderful uses beyond the garden – including in the kitchen, natural medicine, and skin care products.

  • We make homemade calendula oil and calendula salve that can help heal rashes, burns, psoriasis, eczema and more. It’s a star ingredient in our organic skincare line for a reason!

  • According to the Chestnut School of Herbs, calendula tea can ease reflux, sore throats, heartburn, and IBS.

  • I also like to use calendula petals as a garnish to add a beautiful pop of color to a variety of dishes such as salads, beverages, spring rolls, or flower-infused ice cubes.

The blooms are shades of orange, red, and pink. There are also four chickens standing around the wall of annual flowers that are growing, hoping they could get closer to the vegetables growing with the beds themselves.

Tips on Growing Calendula


  • Direct sow calendula seeds outdoors in spring after the last frost, or start seeds indoors up to 6 to 8 weeks before the last frost. (We start our calendula indoors.) In places with mild winters, calendula can be grown year-round!

  • Once planted outside, calendula are fast-growing and will often self-seed (especially if you don’t harvest the flowers). That means they’ll come back as volunteers year after year.

  • Calendula is not picky about soil type, and actually thrives in poor or sandy soil. Some of our volunteer calendula plants grow happily in gravel!

  • Calendula is drought-tolerant and grows best in full sun, though partial shade can be beneficial in places with exceptionally hot summer weather.

  • Expect prolific blooms from calendula in spring through fall. Pro Tip: Don’t be shy about harvesting the flowers. The more you pick, the more they’ll bloom!

2) Sunflowers ~ Helianthus


Who doesn’t love sunflowers? Birds, bees… I know I do! These big cheery flowers always bring a smile to my face. Sunflowers come in a wide array of sizes, shapes, and colors. Personally, I’m a sucker for multi-headed or branching sunflower varieties, which offer an extended season of beautiful blooms and even more seeds per plant.

We love these sunflower varieties: Goldy Double, Autumn Beauty, Evening Colors, Rouge Royal, Lemon Queen, Mammoth, Snack Seed and Velvet Queen. Or, check out this awesome variety pack of over 15 different sunflower types.

Benefits of Sunflowers


  • With their wide open flower structure, sunflowers provide ample easily-accessible pollen that bees go bananas for. Pro Tip: avoid pollen-less sunflower varieties if you want to feed the bees!

  • Sunflower seeds are great source of food and nourishment for wild birds. Our chickens also love pecking at spent sunflower heads near the end of summer. 

  • Wildlife aside, certain sunflower varieties produce big meaty seeds that are ideal for human consumption too, like these “Snack Seed” or Mammoth varieties. You can also grill and eat whole sunflowers heads!

Tips on Growing Sunflowers


  • True to their name, sunflowers prefer to be planted in full sun. Fun Fact: did you know the face of a sunflower moves throughout the day to follow the path of the sun? It is called heliotropism. So keep that in mind when you choose your planting location – they may turn their backs on you! 

  • Sunflowers often grow best when directly sowed outside, though you can start seeds indoors too. To avoid getting too large or root-bound (which can stunt them), I like to start my sunflowers indoors only 3 to 4 weeks before transplanting.

  • Sunflowers vigorous roots may stunt the growth of nearby plants including beans, potatoes, rhubarb and onions. However, we always plant sunflowers in our raised garden beds amongst our veggies and haven’t had issues – minus them casting some unwanted shade at times.

  • Some sunflowers may require staking for support, especially in windy conditions or before they’re well-established.

  • Most sunflower varieties are drought tolerant, so don’t overdo the water!

  • Sunflower seeds are ready for harvest when the plant foliage dies back, flower petals fade away, and the seeds look plump. Seed-save from spent dry flowers at the end of the season.

3) Zinnia


Zinnia flowers are gorgeous pouf balls of vibrant color. They’re another all-around favorite in our garden! Some zinnias grow on smaller, compact plants while others can reach several feet in height. They come in various shades of pink, red, purple, yellow, and even lime green. 

My favorite zinnia varieties include Giant Coral, Giant Yellow, Benary’s Giant (various colors), Aurora, Queen Lime, Giant Purple and Ballerina. For smaller spaces, try these adorable dwarf Thumbolina or Zinderella zinnia (shown in the feature photo at the top of this article!)


Pillowy golden zinnias are in the foreground, a man is sitting on a bench in the background smiling at the view of flowering plants all around. There are squash plants, sage, salvia, as well as various trees throughout the image.

Benefits of Zinnia in the Garden


  • Zinnia are an absolute favorite source of nectar for monarch butterflies. Bees, bumblebees, and hummingbirds enjoy their nectar and pollen too.

  • Zinnia’s tall erect stems make them excellent cut flowers. We usually have several vases full of zinnias throughout our house in summer!


PRO TIP: For long-lasting cut flowers, wait to cut zinnias until the flowers are fully open and the stems are firm (they shouldn’t easily wiggle on top when you jiggle them from below). If cut too young, zinnias will quickly wilt in a bouquet or vase.

Tips on Growing Zinnia


  • Some resources suggest only direct-sowing zinnia seeds outside, saying that they don’t tolerate transplanting well. However, we always start our zinnias from seed indoors without issue! Just be sure to transplant them out when they’re still fairly small (after being properly hardened off) so they don’t become root bound or stunted.

  • Zinnias like full sun but will tolerate a little shade (though they may bloom less).

  • Plant zinnias in well-draining soil that is rich with compost or other organic matter.

  • One bummer about growing zinnias is their susceptibility to powdery mildew, which is rampant here. Thankfully, some varieties are naturally resistant so we try to plant those. See our top tips on managing powdery mildew here.


Pink salmon hued zinnias are growing in front of an espaliered apple tree. Some of the blooms are starting to age and wilt, while one is still a compact green bud which will flower within a few days. There are various potted plants around on the ground in the area.


4) Cosmos


I’ve become slightly obsessed with cosmos lately, planting more and more each season. These dainty daisy-like flowers sit atop long slender stems. They look so whimsical (especially blowing in the wind) and give off a classic cottage garden vibe. While the most common cosmos varieties come in hues of pink and purple, they can be found in shades of yellow, orange, red, and even chocolate too!

We love Blush Cupcake cosmos, Sensation Blend, Candy Stripe, Double Click Rose and BiColor Violet, and the stunning Seashell varieties.

Benefits of Cosmos


  • Cosmos attract a wide variety of pollinators including birds, bees, butterflies, and other beneficial insects. I always see native bees, bumblebees, and birds enjoying ours!

  • On the other hand, cosmos seem to have little-to-no pest issues. Definitely a bonus.

  • The flower petals are edible and can be used as a playful garnish in drinks, salads, and more.

  • Cosmos boast a long blooming season and can be used as cut flowers. 


PRO TIP: Their thin flat petals make cosmos my favorite flowers to dry for pressed flower crafts! I pick and press them all summer to save for fall and winter crafts. Don’t miss our beginner’s guide on how to press flowers.

Tips on Growing Cosmos


  • Cosmos sprout readily and are easy to direct-sow outdoors. (That means they also re-seed as volunteers easily!) Simply scatter seeds on bare soil in springtime after the danger of frost has passed. We usually start our cosmos indoors to get a jump start on the spring season.

  • Cosmos are known to survive in even the poorest soil conditions, as long as it has good drainage. This makes them a perfect “filler” in any oddball place, with little-to-no effort required! They also grow easily in containers.

  • Cosmos are drought-tolerant and prefer warm, dry weather and plenty of sunshine. In extremely hot climates, choose a location with partial shade.

  • Depending on the variety and height, cosmos plants may need staking or other support to prevent the plants from flopping over.


PRO TIP: Deadhead cosmos regularly to promote even more new blooms! Learn exactly when and how to deadhead flowers here, including example photos for cosmos. Regularly removing fading flower heads also reduces seed spread, if that’s a concern.

5) Bachelor Buttons


Also known as cornflower, stunning blue Bachelor Buttons have become one of my favorite annual flowers over the last few years. Classic Bachelor Buttons are bright blue (a magnificent and unique addition to the garden color palette) though they also come in lavender, light pink, and other shades of purple-blue.

A few of our favorite varieties include Blue Boy, Polka dot mix (blue, pink, white and lavender), and dark purple Black Magic

Benefits of Bachelor Buttons


  • Birds and bees absolutely love cornflower. Our native Lesser goldfinches simply can’t stay off of them – and we’re happy to share!

  • The tall erect stems make beautiful cut flowers, and also retain their gorgeous color when dried. I love to press them too!

  • Bachelor button flowers are edible and make an absolutely beautiful garnish. I like to pluck the petals off to add flecks of blue to mocktails, salads, and spring rolls.

  • They readily re-seed, so that means you’ll have free plants for years to come! I simply remove the ones I don’t want, but often leave many to grow – and the volunteer bachelor buttons are usually the first to flower in our garden in spring!

Tips on Growing Bachelor Buttons


  • Bachelors buttons (cornflowers) are easy to start from seed – either indoors about a month before your last spring frost, or directly outside after.

  • They aren’t picky about soil conditions as long as it’s well-draining. Cornflowers are drought-tolerant so they will not thrive in swampy, soggy conditions. Allow the soil to dry out slightly between watering.

  • Plant bachelors buttons in a location that receives full sun, though they’ll tolerate partial shade.

  • Many Bachelor Buttons varieties grow quite tall. In my experience, I usually need a stake, small cage, or other support to prevent the plants from toppling or breaking by mid-summer.

6) Marigolds ~ Tagetes


Marigolds are probably one of the easiest annual flowers to grow. And while they may not be total show-stoppers like some sunflowers or zinnia, what they lack in beauty they more than make up for in utility. Don’t get me wrong! I think marigolds are very pretty, and definitely enjoy the bright pops of orange and red blooms sprinkled throughout our garden. 

My all-time favorite marigold variety is Tangerine Gem followed by French Blend, Naughty Marietta French, Red French, Crackerjack & Red Gem


Many raised beds are full of both vegetable plants and flowers, many in full bloom as the sun sets on the horizon.


Benefits of Marigolds


  • Marigolds are popular companion flowers, often planted among vegetables in garden beds or close nearby. They attract beneficial insects like butterflies, ladybugs, hover flies and parasitic wasps. Furthermore, their pungent aroma can deter pest insects such as aphids, mosquitoes, and Mexican bean beetles.

  • Classic French marigolds in particular are known to repel root knot nematodes, a soil-dwelling parasite that feeds on the healthy root system of plants. To take advantage of that benefit, be sure to leave the marigold roots to decompose in the soil – using a “no till” method to cut the plant out (rather than yanking it out) at the end of the season.  

  • Chickens love to eat marigolds. Our girls love the greens, and often help us “prune” unruly marigold plants that hang over the side of the garden bed. When chickens are fed bright orange marigold flowers, it can naturally dye their egg yolks a deeper orange color!

  • Rich in antioxidants, marigold flowers are also edible for humans – bringing a beautiful pop of color to salads, teas, desserts and more.

Tips on Growing Marigolds


  • Like the other easy annual flowers on this list, you can either sow marigold seeds indoors 6-8 weeks before your last frost, or directly outside thereafter.

  • Marigolds prefer full sun and warm temperatures to bloom most prolifically.  However, we have grown them in partial-shade – no problem! Deadheading spent blooms will also encourage more.

  • They’re not picky about their soil type, and are suitable for containers. Maintain the soil evenly damp but not soggy.

  • If bushy marigold plants start to crowd their neighbors, don’t be afraid give them a good pruning! They don’t mind, and the greens are a great addition to compost.

  • Once they’re established in your garden, marigolds will likely self-seed and return as volunteers.

7) Nasturtium ~ Tropaeolum


Last but not least, nasturtiums are another annual companion flower that I can’t imagine our garden without. They’re edible, attract pollinators, and oh-so-pretty! Their lush cascading greenery dotted with colorful flowers creates an incredibly beautiful and dramatic effect. 

Alaska Mix, Dwarf Jewel, Tall Trailing Mix and Peach Melba are a handful of our go-to nasturtium varieties.


A hand is holding various nasturtium flowers, the colors range from pink to yellow to red and pink. The background shows the nasturtium plants themselves as well as a leaf from an artichoke plant.


Benefits of Nasturtiums

  • Bees and hummingbirds enjoy nasturtium flowers immensely.

  • Nasturtiums double as a “trap crop”, attracting pest insects including aphids and cabbage worms to their foliage rather than your veggies. Ours usually look great despite the pest pressure – but if your plants become heavily infested, I suggest removing leaves or sections of the plant to prevent pest colonization in your garden. 

  • Nasturtiums are edible. Both the flowers and tender leaves have a peppery, zesty flavor – reminiscent of arugula. Try adding both to salads! Our chickens absolutely love eating nasturtium greens too.

Nasturtiums started growing under our artichoke plants and took over once the artichokes died back for the season… but I didn’t mind!


Tips on Growing Nasturtiums


  • Nasturtium generally prefers to be directly-sown, though starting indoors is possible too. Plant once, and they’ll be back! Nasturtiums are another notorious self-seeding volunteer, but one we welcome with open arms. 

  • Nasturtiums are the most shade-tolerant annual flower on this list. They will grow just about anywhere, but flower the most when they receive at least 6 hours of sun. On the other hand, they may look a bit haggard in full sun with extreme heat, so opt for a location with afternoon shade in the hottest climates.

  • Some nasturtium varieties grow into compact bushes, while others sprawl a bit more. Vining nasturtiums can be trained up arches and trellises, or allowed to spill over the side of a raised bed for a beautiful cascade effect. We grow a little of each!

  • Plant in well-draining soil and provide low to moderate water.  


Nasturtium plants are shown growing along a gravel pathway, there roots are in the ground in the perimeter of the yard, yet they are a trellising or cascading nasturtium so they easily spread out. The flowers range in color from burgundy to yellow and gold.

Other Pollinator Flowers


Now of course, there is a whole plethora of other amazing flowers you could grow too! Some of our favorites include lavender, echinacea, salvia, yarrow, scabiosa, flowering herbs like oregano, bee balm, sage, anise hyssop and more!  

I love all of them just as much as the easy annual flowers included on this list. However, they may not be quite as quick and simple to start from seed, may be more particular about climate and care, or are commonly grown as perennials.

    Thank you for this article and your recent posts sharing your company ethos! I really appreciate you speaking out. I am new to growing flowers but had some success last year around the edges of my raised vegable beds and I’m hooked. I have a lot of woodchip mulch areas. Do you have any advice for seeding these areas with annual flowers without having to pull back the mulch? I’d love to just broad cast the seeds but I’m worried they won’t germinate well without soil contact. Maybe I could try species with larger seeds to tuck the into the mulch? Any advice would be appreciated!

      Hi Karen, we are so glad to hear you are hooked on growing flowers! If the amount of seed you need to spread isn’t an issue, some of the seeds will likely sprout readily in your bark mulch, we constantly have volunteer flower and weed seeds sprouting in our gravel hardscape. However, the germination rates will likely be a lot lower than if you started the seeds in containers or they were sowed directly into your garden beds. If you do sow seeds by broadcasting over the area, be sure to do so with anticipation of still getting a number of rain showers to ensure the seeds and eventual plants have enough water for a healthy start.

      Once you get flowers growing in your mulched areas, they will likely reseed the area in time and you should have volunteer plants sprouting up each season (or some growing year round if you are in a mild climate). If you want to ensure even more success, sprout your annual seeds in 6 cell seedling containers and allow them to grow a few inches in height before then transplanting them out and planting under your bark mulch. Hope that helps and reach out if you have any questions, have fun growing!

    Great article, as this is my first spring in mountain home. I was excited to check my seed packets and find that I ended up with several on the favorite varieties lists as I had bought Walmart seeds for zinnias, lavender, cosmos, calendula, etc. A lot of my flowers will be deadheads from the last few years so I know the mass amount of sunflower seeds, for example, are from multiple varieties. Marigolds and “Nasties” were already in my companion planting arsenal but I gained a lot from this write up and I thank you!

    Now, I just need actual spring to get here and stay as my makeshift greenhousing is getting laborious. Hopefully I’ll eventually add on “a Florida room” and capture the great sun from a cold day.
