Description
The Autumn Giant Primus Cauliflower is a superb autumn variety, very vigorous, which offers large white heads protected by beautiful green foliage. This autumn cauliflower is sown from March to June for a harvest from September until the first frosts.
With its immaculate white colour and, in recent years, joyfully yellow, orange or purple, the Cauliflower is a flowering vegetable whose fleshy meristem is consumed. It belongs to the large family of Brassicaceae (formerly Cruciferae) and bears the Latin name Brassica oleracea botrytis. Sometimes called Cyprus Cabbage, Cauliflower is a biennial vegetable plant whose supposed origin is China.
Consumed for the first time in Germany only 300 years ago, this vegetable has earned a special place in our kitchens because it lends itself to many preparations. It can be consumed raw in salads or cooked, plain, in gratin with béchamel sauce or accompanied by a curry sauce that complements its flavor very well. It is a low-calorie vegetable and rich in vitamin C.
There are many varieties of Cauliflowers and each one has a distinct growing season that should be respected. By carefully choosing your seeds, you can have this vegetable all year round.
Cauliflower is a demanding vegetable, requiring excellent base fertilisation and regular moisture.
Harvest: Cauliflower is harvested when its head is well compact by simply cutting it at ground level.
Storage: Cauliflower does not keep very well. It is best to consume it quickly after harvesting. It can be kept for a few days in the refrigerator. You can also freeze it after blanching it for 3 minutes in salted boiling water.
Gardener's tip: The main enemy of cauliflower is the Cabbage White Butterfly (Pieris brassicae), a pretty creamy white butterfly with small black spots that wakes up from April-May to wreak havoc all summer by devouring its leaves. We prefer to prevent it by installing an insect-proof net tightly on market garden hoops. These nets are easy to set up and reusable to protect, for example, your carrot and leek crops.
The untreated or "NT" seeds come from plants grown conventionally (usually with the use of pesticides), however, they undergo no treatment after harvest. These seeds are allowed in organic market gardening when organic seeds are out of stock.

Planting and care
Sowing : the germination temperature of Autumn Giant Primus Cauliflower is around 12° and takes about 14 days.
It is sown from March to June for a harvest from September to December.
You can either sow directly in the ground or prepare seedlings that will later be planted in their final position in the garden.
Preparing seedlings: at home or in a heated greenhouse, from late autumn to late spring, or in a cold greenhouse or nursery for the rest of the year, sow the cauliflower seeds at a depth of 1 cm (0.5in) in a tray filled with good seed compost. Cover lightly with compost or vermiculite. Cover with the transparent lid of the tray or plastic film until germination. Don't forget to keep the substrate moist but not waterlogged!
When the young plants appear strong enough to handle, transplant them into pots and, for seedlings in heated greenhouses, gradually acclimatize them to cooler temperatures before transplanting them into the garden when there is no longer any risk of frost.
Direct sowing: In properly amended and finely worked soil, make furrows about one centimeter deep, spaced 60 cm (24in) apart. Sow the seeds and cover them with a thin layer of fine soil. When the seedlings are well developed, thin them out, leaving one plant every 60 cm (24in).
Cultivation
Cauliflower is a demanding vegetable that requires well-rotted, nitrogen- and potassium-rich soil. It is advisable to apply a generous amount of mature compost (about 3/4 kg per m2) in autumn, by scratching it into the soil to a depth of 5 cm (2in), after loosening the soil as is done for all vegetable crops. It is not very tolerant of soil pH, which should be between 5.6 and 6.5. In acidic soil, it will be necessary to gradually raise the pH by adding calcium in the form of Lime.
Cauliflower, like all cabbages, is quite susceptible to diseases such as Clubroot and pests (Cabbage White Butterfly, Cabbage Fly, Flea Beetle, Gall Midge...), so it is very important to rotate crops for this cultivation.
It is beneficial to associate it with many vegetables such as tomato, lettuce... But avoid planting it near other Brassicas as well as zucchini, fennel, lamb's lettuce, leek and strawberry.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
