31 Self-Seeding Annuals for Effortless Garden Color


Perennials are pretty, but when it comes to big-time garden color, annual plants add a lot of personality and visual appeal. Sadly, they can also be time-consuming and costly. Fortunately, many stunning flowering annuals will reappear each year if allowed to go to seed

These wonderful self-seeding plants not only save time, they also save money. Allowing your annuals to self-seed means that you can skip over the big expense of new plants every year and still have a garden that’s bursting with color and personality. 

Allowing your self-seeding plants to go to seed is one of the easiest ways of planting new seeds. All you have to do is resist the urge to pull those plants until their seed pods have ripened and released their seeds. Nature will do the rest! Here are 31 stunning self-seeding annuals to save time and money in your garden.

Cosmos are wonderful flowers that serve many purposes. They are highly attractive to pollinators and will have butterflies visiting in droves to feast on their sweet nectar. These pretty flowers are low maintenance and create a lot of color with their long blooming season which begins in early summer and lasts until the first frost. 

If you want an all-purpose flower, cosmos make excellent cut flowers, as well. Cutting your cosmos will encourage them to produce even more blooms. Plant these seeds in full sun and keep the soil moist until they are established. Once established, they are drought-tolerant and require very little maintenance.

I love a good flowering vine, and morning glory makes it easy to plant and walk away. In fact, you may want to deadhead this vine before it goes to seed because of how prolifically it reseeds itself.

Morning glories show off their beautiful flowers in the cool mornings, closing when temperatures rise. On cloudy days, morning glory truly shines, as the lack of sun exposure will keep them open all day. ‘Heavenly Blue’ is a luminous variety with cornflower blue, trumpet-like blooms with a cool white throat. 

Poppy

Poppies bring big, bold, gorgeous colors to the landscape, and most types self-seed freely and reliably. They make great cut flowers and are naturally deer-resistant and drought-tolerant. Plant your poppies in full sun and fertile, well-drained soil for the best results. The bowl-shaped flowers will attract pollinators and look stunning in a floral arrangement. 

In addition to beautiful and unique flowers, poppies have quirky and attractive seed pods. Allow them to dry on the stems and either pop the tops off and give them a little shake or let nature run its course, and the wind will help to scatter your poppy seeds.

If you harvest the seeds, know that poppy seeds prefer to be directly sown, so no worries about starting seeds indoors. Just toss them in the garden in the fall and allow them to vernalize over winter.

Coreopsis

Plains coreopsis flowers bloom vividly, their golden petals radiating against a soft, blurred backdrop of feathery foliage. Each blossom boasts a captivating contrast, with yellow petals embracing deep red centers.

For a mass of colorful blooms from summer through frost, coreopsis delivers every time. In warmer climates, they can even bloom well into the winter. Deadheading your plants will keep them producing bushels of blooms that draw pollinators like a magnet. To let them go to seed, simply let the flowers dry on the stem. 

Coreopsis are versatile plants that can be happy in full sun or partial shade. Their stems will get a bit leggy in partial shade, but the flowers are very lightweight and don’t weigh down the slim stems. They are drought and heat-tolerant and make nice cut flowers, as well. 

Alyssum

A close-up reveals a cluster of delicate pink alyssum flowers, their petals forming a captivating bloom. Illuminated by gentle light, the flowers exude a soft, radiant glow, creating a picturesque scene of natural beauty and tranquility.

Sweet alyssum is a delightful little plant that makes a wonderful ground cover. It can be grown as an annual in almost any climate, but it will reseed reliably in zones 5-9. Native to the Mediterranean region, alyssum begins blooming in spring and continues until the first frost. Planting them in a space with afternoon shade will keep them blooming through the hotter months

Initially, plant your alyssum seeds in fall for blooms in late winter and an extra long blooming season. Newer varieties have been bred for increased heat and drought tolerance. Temperatures over 85°F (29°C) will start to slow down flower production, so a bit of afternoon shade in summer will help keep flowers on your alyssum.

China Aster

China asters are fast growing and bloom for a long period, from late spring through the fall. Flowers are most commonly shades of purple or blue, but they can also be pink or white, depending on the variety.

Sow your seeds a week or two after the last expected frost, and after they sprout, give them some mulch to protect their shallow root systems. Asters like to be kept moist, so planting them in partial shade may help to keep them looking good during the heat of summer. 

This plant can self-seed aggressively, so it’s a good idea to deadhead, leaving only a few flowers to go to seed at the end of summer. China asters have an excellent vase life, so cutting them for floral arrangements will help keep these plants in check and control how many plants you will have next season.

Also known as cornflowers, which is where the color cornflower blue originated, bachelor’s buttons are hardy little plants that can grow in a wide range of climates and soil types. They are drought tolerant, and while blue is certainly the most common color, it is far from exclusive. These flowers come in many shades of purple and pink, as well as white.

Bachelor’s button plants self-seed so well that they are considered invasive in some states, but they are quite pretty, and if they aren’t invasive in your area, they truly make a wonderful addition to the garden. They require little to no maintenance, and pollinators appreciate their presence, as well. 

Calendula

Calendula is a wonderful and useful plant that produces pretty orange and yellow flowers and attracts a host of beneficial insects to the garden. It is often referred to as pot marigold. However, the two are not closely related. The leaves and flowers are edible and are often used in salads or as garnish. A preparation made from the plant is also commonly used to treat cuts and scrapes. What a great little plant!

Calendula self-seeds well and sometimes escapes from the garden, but it will not overcrowd native plants, so it is not considered invasive. Plants are happy in full sun or partial shade and are quite drought-tolerant. The flowers are great for cutting, and deadheading will keep your calendula blooming all summer long. 

Celosia

Fuchsia-hued celosia flowers stand out against their foliage, characterized by green leaves accented with pink edges. Resembling the flamboyant crest of a rooster, these unique blooms captivate with their intricate form and vibrant color palette.

Other types of celosia produce flowers that are flamelike or resemble fuzzy little fingers. These amaranth relatives of amaranth look unique and make a statement in the flower garden. 

Celosias make great cut flowers and add a really interesting element to a floral arrangement. Their leaves are edible and have a mild, spinach-like flavor when cooked. Celosia self-seeds freely, but the seedlings are easy enough to pull up wherever they are unwanted. Leaving them to go to seed will feed birds and your garden, too! 

Dianthus

Fuchsia pink dianthus flowers capture the sunlight's warmth and glow, radiating an aura of natural beauty. Slender stems gracefully uphold these delicate blossoms, offering support and elegance as they sway gently in the breeze.

Dianthus, a genus that includes the ever-popular carnation, is technically a short-lived perennial, but it is only reliably perennial in zones 6-9. Elsewhere, dianthus is a spicy-scented annual that can self-seed if its flowers are left on the plant.

It’s difficult because they make such excellent cut flowers, but it’s worth leaving a flower or two at the end of the season to see these beauties pop back up in spring. 

These sturdy plants prefer full sun and well-drained soil. Most varieties have fragrant flowers, with clove-like being a common way to describe the aroma. Their pretty ruffled petals and ease of care have made these very popular garden plants.

Feverfew

This sweet little flowering herb has been popular since its use in Victorian gardens. It is technically a short-lived perennial, so individual plants will leave for two to three years, but it self-seeds very well, so once you plant this herb in your garden, it will stick around for a long time. The masses of small white flowers on feverfew have earned it the nickname bride’s buttons.

Deadhead your feverfew throughout the summer to keep the flowers coming. The more you cut, the more this plant will produce. Feverfew will bloom from summer through the first frost, and if you leave some flowers on the plant near the end of the blooming season, it will self-seed nicely.

Marigolds are a much-loved garden staple. These phenomenal flowers are great for adding color to the garden, and they repel some types of flies that can be harmful to other plants. In addition to their functional and ornamental usefulness, marigolds are also edible and make a stunning garnish or addition to baked goods

We don’t typically consider marigolds self-seeding, but they are indeed. A month before you expect the first frost, stop deadheading your marigolds and allow the seed heads to dry on the plant. They will burst open and drop their seeds, and you should see some baby plants pop up in spring. 

Impatiens

A close-up captures delicate impatiens flowers, their soft petals unfurling gracefully amidst leaves. The blossoms, a mesmerizing spectacle, transition from a pristine white hue, gradually deepening into a crimson.

Impatiens are attractive flowering plants that prefer partial shade and are perennial in zones 10-11, but elsewhere they will self-seed if their seed pods are left on the plant. Something to bear in mind with these plants is that hybrid varieties won’t always breed true, and you may get a few surprises in their place, but that can be a good thing.

These are mounding plants, and they are not aggressive about self-seeding. Impatiens look stunning in a mass planting. They need rich, moist soil, and in exchange, they will provide a great deal of color from summer until the first frost. 

Petunia

Petunias are fast-growing, low-maintenance sun lovers that thrive in garden beds and containers. Sadly, they are only perennials in zones 10-11. They will, however, self-seed in cooler climates if you allow them to go to seed. Much like impatiens, hybrid varieties will not always breed true, so it’s difficult to say what your new flowers will look like.

With so many beautiful varieties available, there is a petunia for every garden. Petunias like fertile soil and a moderate amount of water. They bloom best in mild weather, so don’t worry if your petunias slow down their blooming mid-summer. They will bounce back when the weather cools off in fall

Snapdragons are tender perennials in zones 7-11 but may self-seed in cooler climates where they are grown as annuals. They are cool weather bloomers that prefer temperatures between 40°-70°F (4°-21°C) and will stop blooming for a time midsummer but usually bloom again in fall as long as they survive the hot summer weather.

Plant your snapdragons in partial shade with morning sun for best results. This will help to keep their roots cool during the hottest months. These plants are very resilient despite their delicate appearance and can even survive a light frost or two once established. They are one of my favorite flowers for the cutting garden. 

Strawflower

Strawflowers retain most of their color when dried. Plant your seeds in spring for blooms that start in early summer and continue until the first frost.

Strawflowers do self-seed and are most successful in mild climates, although they may still seed themselves in cold climates if they don’t have to contend with weather that is cold and wet. These plants prefer dry weather and average, well-drained soil.

Sweet peas might surprise you with their amazing cold tolerance. However, they are annuals in all zones. They self-seed very well, though, and all you really need to do is leave a few flowers to dry on the vine. In mild climates, sweet pea seeds may sprout in late fall and grow through the winter, as they can tolerate temperatures as low as -5°F (-21°C).

These climbing vines like to have a structure to climb, and they flower prolifically from early spring until early summer. Cutting the flowers or deadheading will help to control how aggressively this plant reseeds itself. The flowers smell wonderful and have a great vase life.

Hyacinth bean stands up to heat and drought and produces the prettiest purple flowers that smell great and look great in a floral arrangement.

You can plant hyacinth beans just about anywhere. I’ve pulled up volunteers and transplanted them with tons of success. They do self-seed aggressively, but the seedlings are easy to spot with their purple stems and veining on deep green leaves. Removing most of the seed pods will help to control the spread if you only want a few vines.

The flowers are large and have a fuzzy texture. 

If left on the plant to dry, the flowers will go to seed, and they self-seed well. Plant these in a spot where other, smaller plants won’t have to compete for nutrients. Most varieties grow quite large, and they are heavy feeders. They make a spectacular cut flower, and the seeds are edible as well.

Plant your borage seeds in full sun to partial shade. This plant isn’t picky about soil and rarely needs fertilizer. It does self-seed aggressively in some climates, so deadheading will help prevent more borage than you know what to do with. The leaves are also edible but are best picked young as they get a bit hairy as they mature.

The attractive leaves resemble lilypads, and are edible as well. They have a green and peppery flavor. Nasturtiums are fast-growing and sturdy, and while people like to eat them, rabbits and deer do not.

Nasturtiums work well in the ground or a container and look lovely spilling over the edge of a raised bed. They attract pollinators and make great companions in the vegetable garden. Plant in spring as soon as the ground is workable, and you will have flowers from spring until the first frost. If you leave the seed pods at the end of the season, this plant will self-seed readily.

Sunflowers self-seed quite well. The only issue you might run into is that everyone loves to snack on sunflower seeds. If you’ve ever tried growing sunflowers from seed, you’ve probably learned the hard way the lengths to which squirrels will go to find these seeds. If you can manage to keep birds and other critters away through the winter, you might see some sunflowers popping up in spring.

Who knew tobacco flowers were so delightful? Flowering tobacco is a lovely annual that produces a great number of star-shaped, wonderfully fragrant flowers from summer through fall. The plant is perennial in zones 10-11 only and grown as an annual elsewhere, but it does self-seed. Allowing it to go to seed is the best way to keep this plant in your garden.

Flowering tobacco will bloom best in full sun but can survive in partial shade. The flowers come in shades of white, yellow, green, red, and pink, and most types are strongly scented. They prefer rich soil, taking in a lot of nutrients, and they self-seed readily. The seedlings are easy to find and pull if this plant gets out of hand.
