Cauliflower is a beloved vegetable grown in gardens worldwide Its sweet, nutty flavor and velvety texture make it a tasty addition to many dishes But before you can grow a cauliflower plant and harvest those delicious heads, you need seeds. So how exactly are cauliflower seeds formed?
Cauliflower is a biennial plant, meaning it takes two years to complete its life cycle from seed to seed production Here is an overview of how cauliflower seeds are formed
Year 1: Vegetative Growth
-
In the first year, cauliflower grows vegetatively, developing leaves, stems, and roots. Gardeners typically sow cauliflower seeds indoors 6-8 weeks before the last frost date The seedlings are later transplanted into the garden after hardening off.
-
Given adequate sunlight, water, and nutrients, the young cauliflower plant will continue growing through the summer. By late summer, it develops a compact head made up of undeveloped flower buds. This is the edible curd that we know as cauliflower.
-
Commercial growers will harvest the curd at this point. But if saving seeds, allow the curd to remain on the plant unharvested as it continues growing into fall.
-
As temperatures cool, the plant will go dormant for winter. In cold climates, dig up and store the plant over winter. In mild winter areas, it can remain in the garden. The key is preventing premature seed stalk development.
Year 2: Flowering and Seed Production
-
In spring of the second year, the overwintered cauliflower plant resumes growth. It sends up one or more seed stalks topped with small yellow flowers. Cauliflower is insect-pollinated.
-
After pollination occurs, the flowers fade and long, narrow seed pods develop in their place. Inside these pods, the fertilized ovules mature into plump cauliflower seeds over summer.
-
By mid to late summer, the seed pods turn tan and dry out. At this stage, they split open, releasing the ripe cauliflower seeds. Seed harvest typically occurs in July or August.
Harvesting and Processing Cauliflower Seeds
-
Cauliflower seeds must be harvested by hand before the pods burst open. Pinch or cut off the pods individually as they mature.
-
Dry the harvested pods further indoors before opening them to extract the seeds. Rubbing the pods releases the seeds.
-
To separate seeds from chaff, winnowing and sieving are used. Larger debris is removed first before blowing off the chaff.
-
Fresh cauliflower seeds are plump and black. After drying, they turn a reddish-brown color.
-
Allow seeds to dry for 1-2 weeks before storing in an airtight container in a cool, dry location. Properly stored, cauliflower seeds remain viable for 4-5 years.
Protect cauliflower from the sun
Plenty of sunlight supports the cauliflower during the growing phase. However, if there is too much sunlight before harvesting, you should protect the white heads. A good way to do this is to fold the surrounding foliage in half over the cauliflower head. This causes minimal damage to the plant and can prevent sunburn. Cauliflowers may turn yellow or purple if you don’t cover them, but they are still perfectly safe to eat.

As a horticulture student I mainly studied crops and cultivation techniques. It fascinates me how many diverse plants can grow from small, nearly identical seeds. Favourite fruit: blueberries, grapes, raspberries, pears Favourite vegetables: mushrooms, peppers, kohlrabi, onions, garlic.
Cauliflower has become a real staple vegetable in our diets. With the right care and attention, you can grow a delicious crop of cauliflowers in your own garden.
Cauliflower (Brassica oleracea var. botrytis) looks very similar to broccoli (Brassica oleracea var. Italica). And no wonder – the two brassicas are closely related. Here you can find out about cauliflower’s origins, how it grows and how to ensure an abundant harvest.
It is thought that cauliflower came from South West Asia and then spread to Europe through Italy in the 1600s. It has been picked, crossed, and bred for hundreds of years to become the big, white vegetable you see in stores today. Now it is grown all over the world and is one of the most popular types of brassica. As the name cauliflower suggests, it is usually the clusters of flower sprouts that are eaten.
If you want to cook something different, you can boil or roast cauliflower, eat it raw, or even make “cauliflower couscous.” It is rich in vitamin C, B-vitamins, fibre and other essential nutrients. But it is not just the cauliflower head that you can use in cooking. Read our article on how to pick, store, and use cauliflower to learn what to do with the leaves and how to keep them fresh.

FAQ
How do you get cauliflower to form heads?
What happens when cauliflower goes to seed?
How does cauliflower produce seeds?
How long does it take to grow cauliflower?
The process that includes a seed sprouting and the first leaves starting to appear is called germination. Cauliflowers are annual plants that grow from seeds. Cauliflowers are best planted during spring or fall. If so, you’ll get the harvest in three to five months. You can either start the cauliflower life cycle in seed trays or in the garden.
How do you plant cauliflower seeds?
Use a chopstick or pencil tip to press a little hole into the mix in each cell. Sow each cauliflower seed about 1/4″ deep and cover with seed starting mix or moist potting soil. Plant only one seed per cell to avoid the need to thin seedlings later. 3.
What do cauliflower seeds look like?
Cauliflower seeds are small and round, similar in size and shape to a peppercorn. The seeds range in color from tan to dark brown to black. Cauliflower seeds should be started indoors in late winter or early spring. For winter gardens, seeds can be sown directly in the ground and should be planted in early fall.
Can you grow cauliflower from seed?
Cauliflower is one of those weird brassica crops that you grow for the edible flower head, though the frilly-edged leaves are also edible and taste a bit like kale. Let’s look at how to grow your own cauliflower from seed and end up with a nice, tight head at harvest time!
How long does it take for cauliflower seeds to germinate?
After sowing the seed of the cauliflower plant, you must cover them with a thin layer of soil and sprinkle some water on top to keep it moist. Within eight to ten days, your seeds will begin to germinate. At this point, the plant will need sunlight, water, nutrients, and proper temperature.
Why does cauliflower produce flowers and flowers?
This is because, during this stage, the cauliflower starts to produce buds and flowers. The production of flowers and buds is a sign that the plant is planning to reproduce. These flowers will start making pollen that’ll be waiting to be carried to a new spot to start a new cauliflower plant.
