5 Flowers to Grow Through Winter in Southern California
In my last post, I covered the main crops I grow during the cool season here in zone 10b, but did not quite get around to the discussion of flowers—which really bothered me because you know I love flowers. ♥ This article will go over some of my favorite Winter flowers to grow, but be aware that there are more! If you have to prioritize space (like I do) you’ll find that most of these flowers serve multiple purposes and are therefore great additions to small gardens.
The cool season (or Fall/Winter) here in zone 10b, Southern California, extends from October/November-April/May. We don’t get temperatures below 30 degrees F, and our rare frosts usually happen anywhere from December-February. When I talk about plants for the cool season, this usually means I plant them out into the garden (or direct sow) at the beginning of the season in Fall and maybe again after we have our frosts.

Flower Seeds or Transplants?
Before I get to listing my favorite Winter flowers to grow, I’d like to remind you that I start most of my plants from seed. For the cool season plants listed here, I usually have to start my seeds in Fall (you can watch my 2023 Fall Sow-Along). This is mainly because the varieties you can purchase as seeds are far more interesting, colorful, and unique than what most nurseries offer. Growing from seed also saves me money from year to year—and I even trade seeds with my garden friends so we can all try new varieties without having to buy entire seed packets. If you are intimidated at the idea of growing a garden from seed, please check out my Seed Starting section or feel free to leave a comment and I’d love to help. You can also find a list of dependable and quality seed sources on my Where I Buy Seeds page.
That being said, sometimes it is much more convenient and helpful to buy transplants at a nursery. If you have a local nursery and prefer to purchase baby plants or “starts” I’m happy to say that I’ve seen most of the flowers on this list sitting on nursery shelves just waiting for a place in your garden.

Calendula (calendula officinalis)
Calendula is probably my favorite Winter flower. Now, for many other areas of the country, calendula is a Spring and Summer flower, but in zone 10b I find that my calendula grows best in our cool season. The plants will survive and produce some blooms through the Summer, but in our heat they typically stay small and produce smaller blooms in the hotter months.
Why grow calendula? Not only is calendula cheery and beautiful, but it is also well known for its edible and healing properties. Dried calendula blooms can be infused into oil to make salve or my favorite calendula whipped body butter. The fresh petals looks inviting when sprinkled over salads. Calendula is also a wonderful companion plant for brassicas. While companion planting is not foolproof, I do find that pairing calendula with brassicas and alliums in the winter garden is a winning combination! Finally, calendula is one of the best self-seeding flowers that will provide you with plants for seasons to come!
If growing calendula for healing purposes, I recommend growing the ‘resina’ variety. This specific type of calendula is supposed to have the highest content of resins (the main healing component) than any other type. Check out these resina calendula seeds!

Pansies (Viola x Wittrockiana)
Jazz up those winter harvest baskets with these edible flowers! Pansies look gorgeous sprinkled over salads, sugared and placed atop desserts, or even pressed to make some flower frames like these. Pansies do not grow to be very tall, so use them more around the borders of your garden for a pop of color.
Pansies just might be the ideal Winter flower to grow. I can personally attest to the frost tolerance of pansies. A couple years ago we had a frost of about 30 degrees F where I found my pansy foliage completely frozen like ice cubes. By midday, they were just fine and back to normal. That is not always the case for some flowers, such as nasturtiums (discussed below). I grew all the pansies in the picture above from seed, and I would consider them pretty easy to start from seed at home. Cheaper too! Just give them ample time to germinate and know that they aren’t the fastest growers.
In terms of growing pansies from seed, it is much more difficult than other winter flowers to get them to germinate. On the other hand, once you have pansies in your garden, they will self-sow/seed readily. Haha! Personally, unless there is a specific variety you want to grow, I recommend buying pansies from your local nursery and planting them.
Snapdragons (Antirrhinum majus)
I like snapdragons because they create visual interest with their spire-like shape. They are also easy to grow and had no problem surviving some frost in our garden (note: the lowest temperature we get is about 30 degrees F but they are rumored to survive down to 18 Degrees F).
Snapdragons make an excellent cut flower for the Winter garden and add color to the landscape. While they can be grown as short-lived perennials in mild climates, I have had the best success growing them as annuals in regards to reliability.
I am a huge fan of the ‘madame butterfly series‘ snapdragons. They are a type of snapdragon that is full, frilly, and fluffy (pictured below)!
Stock (Matthiola Incana)
Do you like flowers that smell good? Well, you need to grow stock! It’s hard to describe the smell of these luscious flowers, but it’s extremely powerful and somewhere between a tuberose and a gardenia, maybe?
Stock makes an excellent cut flower, although it can bother some people that are sensitive to strong smells. I grew stock for the first time last year and enjoyed it so much, yet also learned some important growing tips:
Tips for growing stock:
Stock comes in two varieties: column and spray
Columnar stock only has one central stem, which means you should not pinch the top. This will essentially remove the only flower tip. Column varieties will only give you one flower stalk per stem.
Spray varieties will branch on their own but are also good for pinching.
When purchasing seeds, I recommend buying a spray variety of stock. It’s a lot more worthwhile!
Stock will self sow like many of my favorite self sowing flowers on this list.
According to the Johnny’s Selected Seeds website, stock is an edible flower: “The peppery, clove-like flavor of the flowers lends itself well to use as a garnish on salads, desserts, and drinks.” Between it’s delicious smell and the fact that it can be an edible garnish, I’d say stock is very high on my list of Winter flowers to grow.
Nasturtium (Tropaeolum)
Another dual-purpose, edible flower for the Fall & Winter garden! Nasturtiums come in all sorts of colors and growing habits. Some are more bush-like while others tend to spill over garden beds and grow almost like a ground cover. I’m going to try to grow mine vertically like vines this Winter. If you’ve never made nasturtium leaf pesto, you’ve got to try it! The seeds can also be pickled like “capers” and the flowers themselves have a slight peppery flavor.
Remember how I mentioned companion planting for calendula and brassicas? Well, nasturtiums can also act as a trap crop for cabbage caterpillars that typically go after brassica leaves. The idea is that those green caterpillars will eat your nasturtium plants instead of your cabbages and kale. I talk about this and more organic pest control in How to Prevent Pesky Cabbage Caterpillars.
While I find nasturtiums easy to grow, there are some things to note about their preferred climate. First, nasturtiums don’t like Summer heat here in zone 10b. Mine quickly fade away unless planted in shade in our hotter months—Fall and Winter actually end up providing the best climate for these amazing, edible flowers. Second, they are unfortunately NOT frost tolerant—the water content in their leaves ends up turning them to slime after a frost. So, when is the best time to sow nasturtium seeds? Simply direct sow them in Fall for a Winter crop, and again after the last frost for a Spring crop. In all honesty, I let my nasturtiums go wild and self seed, so they decide when to pop up and grow, but definitely include this lovely ground cover in your cool season garden.
Grow that Winter Garden!
You know I’m a big fan of intermixing flowers and vegetables. It’s colorful, fun, and also provides great benefits for pollinators and other beneficial bugs. I hope these flowers have inspired you to add them to your garden spaces this Fall & Winter.

Flowers! 🙂
Hola again Randi, dang… another thi g in excited about, flowers! I have a calendula and nasturtium that are toughing out the summer and I can’t wait for them to take off as soon as it cools down! I’m going to be expanding a little more in the garden over the winter becasue I absolutley want more flowers during every season 🙂 Another fun read that now has my imagination running through a flower filled garden in the near future, thank you…
You three be well out there, stay safe and enjoy your the rest of your day, week and the coming weekend 🙂
You are on it Rod! Both with commenting and flowers! It’s always nice to have the calendula already waiting in the garden for the weather to be perfect. You’ll have a head start. I’m really excited to see you growing those. I also think some snapdragons would look awesome in your space. Thanks for reading!
Hi again Randi- Do you direct sow your stock or start indoors? I would really love to try growing but don’t have the indoor setup yet.
Hello! At first I would follow my Fall/Winter seed starting protocol which is starting outdoors in seed cells. It’s warm enough for seeds to germinate. As nights cool down (like now), I’d start them indoors and then immediately move any cells that sprout to my outdoor station. Recently, I scattered the dead stock pods in areas of the garden directly, and they have sprouted on their own! So, I’d start them in cells to be safe, but also feel free to experiment with direct sowing maybe with your homegrown flowers in the future!
I am newbie when it comes to planting annuals in the garden, this year I want to start planting annuals and flower perennials. I water by hose and the sprinklers help as they reach into my garden beds as well. I am just afraid if I plant them in a raised bed that I might damage the flowers when watering. Also, I don’t know if of any good flowers to grow as I am in southern California. I will try the ones you mentioned, is it too late to plant for winter? Also, any recommendations on the type of food to be feeding annuals?
Hello! I’m excited you are growing more flowers! It’s not too late to plant Winter annuals if you go to the nursery and buy some healthy starts. In the past, I’ve written some articles on flowers that do well here in Southern California if you use the search function on my site. Recently I shared about self sowing flowers that make our jobs easier! You can read that article here: https://freckledcalifornian.com/2022/10/31/self-sowing-volunteer-flowers/
Another flower article that comes to mind is: https://freckledcalifornian.com/2019/04/17/best-flowers-for-a-potager-garden/
As for feeding plants, I tend to follow the idea that we nourish the soil, and not the plants necessarily. I use lots of compost to amend my garden and worm castings. Occasionally I’ll water with an organic fish/seaweed fertilizer or sprinkle an organic all-purpose fertilizer when prepping my garden, but the more I treat my soil well, the less I find it necessary. There are soil amending articles on the blog too for further details. Hope that helps!
I just moved into a new place in Bakersfield CA, zone 9b. It is already December 8 today and I finally have time to do some planting here in what is an otherwise very boring yard, plantwise!! Is it too late to put in anything that will grow and bloom before Spring arrives? Any advice or suggestions would be greatly appreciated on what to plant this time of the year that blooms or is perennial and will come back next season. I am trying not to waste money on annuals that do not last. I know it is late in the season for planting but I thought I would ask anyway. I am anxious to have a nice garden all year long.
I prefer flowering plants to food plants overall and rarely plant eatables.
Hi Howard! I must admit, edible plants and zone 10 tend to be more my specialty, but you could still plant flowering bulbs (daffodils naturalize wonderfully) that could bloom in Spring. Most of the plants that come to mind right now are annuals (like pansies) or scattering California native wildflower seeds. While wildflower seeds won’t necessarily bloom before Spring, they will get a head start and bloom earlier for you. Also, even though they are annuals, if you let them self-seed around your garden they will come back each year. Lastly, I’d suggest simply stopping by your local nursery to see what they are selling and ask an employee. Honestly, local gardens and nurseries are often the greatest indicators of what will grow successfully in your area.
