Before you put away your trowel and hang up your sunhat for the winter, I have some good news for you. Right now, as the weather is cooling off and the garden is once again a pleasant place to spend time, there’s already much you can do in the fall to prepare your garden for spring. Here, we’ll share 39 seeds you can plant in autumn for beautiful spring blooms!
We don’t typically don’t think of fall as an ideal time to start flower seeds. Certainly, some winter vegetables prefer to be grown during the cooler weather.
Garlic and onions, for example, are best planted in autumn, as they grow best in cooler weather. But did you know that many flowering plants enjoy a bit of cold weather before they grow in spring?
Why Plant in Fall?
The answer to this question is multifaceted but relatively simple. For one thing, there are fewer garden chores and more comfortable hours during the day. With the temperatures falling, it is no longer a game of seeing how long you can tolerate being outdoors before melting into a puddle of sweat.
In fall, most weeds are dormant, so there are fewer pesky plants to contend with, making the job more pleasant in general. You can prep your fall beds in one weekend and not worry that they will be full of weeds by the time the next weekend rolls around and you’re ready to do your planting.
Seeds planted in fall also have a leg up on weeds compared to spring-planted seeds. Seeds already sown will have a few weeks to start the growing process before the weeds creep in and compete for nutrients. When the weeds sprout in spring, your flower seedlings will be easily distinguishable, and weeding will be much easier.
Finally, many types of flowering plants require a period of cold temperatures before their seeds will germinate. This process, known as cold stratification, mimics nature. These flowering plants will self-sow their seeds in the late summer or fall; when spring rolls around, the gradually warming temperatures indicate to the seeds that it’s time to spring to life, but they won’t know that if they aren’t exposed to the cold!
When to Plant
Successful gardening can be boiled down to imitating nature. Most plants shed their seeds in late summer or fall. These seeds spend winter in a state of dormancy and germinate as soon as the soil temperature is right. The closer we can mimic this process, the more likely our seeds will thrive.
The question of timing is going to depend significantly upon your climate. In colder climates, waiting until a killing frost has occurred is best.
This ensures that your seeds don’t have time to sprout. Avoid letting your seeds sprout because they are unlikely to survive the cold. We want them to remain dormant throughout the winter.
If your seeds sprout due to some unexpectedly warm weather, there are some measures you can take to protect them. None are foolproof. If you see seedlings pop up, cover them by spreading a thick layer of mulch. This will help to keep them insulated.
Aim for late fall to early winter in warm climates that typically don’t experience freezing temperatures. If you live in a climate with a rainy season in winter, try to get your seeds in the ground before the onset of that rainy season.
How to Plant
Follow the instructions on your seed packets when sowing your seeds. Your seed packets should give you clear directions. Since all plants do not have the same needs, there is no one-size-fits-all solution to how to go about planting seeds.
Something to note is whether or not your seeds require cold stratification. Fall planting is perfect for seeds that require cold stratification, as this process exposes seeds to moist, cold conditions to encourage them to germinate.
This happens naturally for plants that reseed themselves. These plants drop their seeds, which overwinter beneath a layer of cold earth or snow.
Cold stratification can be carried out by placing your seeds in a container with potting mix in the refrigerator for some time, typically equal to one month. While this is a perfectly valid way to carry out cold stratification, fall planting will accomplish the same objective.
For best results, clear your bed as you ordinarily do. Clear away any weeds and leftover debris from the prior season.
It’s a great idea to amend the soil at this time. Organic soil amendments need time to break down, which makes fall the perfect time to get them in place and allow them the time they need to enrich the soil. This can be done with a layer of compost or a similar enriching agent such as worm castings.
Now comes the tricky part; I say that because it is almost too simple. Spread your seeds over the soil and compress them lightly. You can accomplish this by walking over them. All you want to accomplish here is to set them into the soil so they don’t blow away. Think of how a plant would drop its seeds. This is what you want to replicate.
Avoid the urge to cover your seeds with mulch, straw, or anything else. Just let them be. Even if birds come to have a snack on your freshly sown seeds, it shouldn’t be a problem. There will be plenty left behind.
When spring comes, make sure that your flower bed remains moist. You are unlikely to have to do much watering, but if the soil appears to be drying out, give it some water. Once your seeds sprout, don’t allow the soil to dry out completely.

Morning Glory
botanical name Ipomoea | |
sun requirements Full sun | |
height 6-10’ | |
hardiness zones 2-11 |
Morning glory likes to climb, so plant these seeds in a spot where the plant will have a structure to hold onto. A sunny, bright location is very important. The flowers will not open without 6-8 hours of daily sunshine.
Keep the soil neutral to acidic and moist but well-drained. They’re invasive in some areas, so deadhead if you don’t want them to reseed.
Nasturtium
botanical name Tropaeolum | |
sun requirements Full sun | |
height 6-12” | |
hardiness zones Perennial 9-11, Annual elsewhere |
If you fancy edible flowers, there is no lovelier specimen than the nasturtium flower. Nasturtiums like cool weather. They are an excellent trap plant for aphids!
They may die off in summer in warmer climates, but they reseed themselves freely, so they should return when the weather cools off again. Nasturtiums typically prefer poor soil, as too much nitrogen will mean more green growth and fewer flowers.
Pansy
botanical name Viola tricolor var. hortensis | |
sun requirements Partial sun | |
height 6-12” | |
hardiness zones 6-10 |
Another edible flower, the pansy is the epitome of spring and comes in many different colors and color combinations. The wonderful thing about these plants is that they will stand up to a light frost, so there is no need to worry about them sprouting early.

Poppy
botanical name Papver | |
sun requirements Full sun | |
height Varies widely | |
hardiness zones 2-10 |
You can’t go wrong with poppies. The birth flower of August has an excellent, long blooming time, from late spring through the summer, going dormant during the hottest months and returning as the weather cools.
Poppies do best when directly sown and left uncovered, as they need light for germination. Give them well-drained soil.
Purple Chinese Houses
botanical name Collinisia heterpohylla | |
sun requirements Partial shade | |
height 1-2’ | |
hardiness zones 2-11 |
Add this butterfly host to your spring garden to draw a host of pollinators, including bees, butterflies, and hummingbirds. Purple Chinese houses are named for their tiers of purple blossoms that resemble a Chinese pagoda.

Sweet Peas
botanical name Lathyrus odoratus | |
sun requirements Full sun | |
height 5-6’ | |
hardiness zones 2-11 |
Sweet peas make excellent cut flowers with their sweet fragrance and intricate blooms. A native of Mediterranean regions, these plants prefer soil that is sandy or loamy and well-draining.
Some varieties are bushy, while others are climbers and will enjoy a structure to climb. Pick your sweet peas often to keep them flowering rather than going to seed, especially in hot weather.
Tickseed
botanical name Coreopsis | |
sun requirements Full sun to partial shade | |
height 6”-4’ | |
hardiness zones 4-9 |
This big bloomer is not picky and will continue to bloom from spring straight through to fall as long as you deadhead it and shelter it from the heat of the afternoon sun.
Full morning sun is Tickseed’s preference. These low-maintenance flowers are drought-tolerant and make wonderful cut flowers. They will reseed if the birds leave their seeds uneaten.
Veronica
botanical name Veronica | |
sun requirements Full sun | |
height 6”-3’ | |
hardiness zones 3-11 |
Veronica, also known as speedwell, is a flower that is likely familiar to you from places where cut flowers are sold. The tall, neatly arranged flower spikes make perfect airy elements in a cut flower arrangement.
