Romanesco broccoli is a remarkable Italian vegetable, similar to cauliflower in taste and texture. It forms beautiful whorled, apple green heads that are very ornamental and have a subtle, delicate nutty flavour. It is sown from May to June and harvested from August to December.
Romanesco broccoli, also known as Roman cauliflower, belongs to the large Brassicaceae family (ex-Cole family). This biennial plant is grown as an annual for its edible flower heads that are harvested just before they start to bloom. It is native to Italy where it has been grown since the 16th century. Romanesco Broccoli has a delicate, nutty taste. It is delicious lightly steamed and added to gratins, quiches, purées or stews. It also goes very well with curry. From a nutritional point of view, it is very healthy: it is low in calories but very rich in vitamins, fibre and minerals.
Romanesco Broccoli is an easy vegetable to grow as long as you meet its basic requirements: deep, rich soil, and regular watering. It enjoys plenty of sun and generally does well in cool and rainy climates.
Harvesting: To harvest Romanesco Broccoli, simply cut off the central flower head with a sharp knife when it feels suitably compact and heavy.
Storage: Fresh Romanesco broccoli does not keep very well. It is best to eat it quickly after harvesting, although it will keep for a few days in the refrigerator. It is also possible to freeze the florets, after having blanched them in boiling salty water for a few minutes.
Good to know: For the past few years, swede midges (Contarinia nasturtii) have been causing considerable damage to brassica plants. We recommend protecting your crops with insect netting from mid-May to mid-July.
Even if the vegetable garden is first and foremost a place for growing great quality veg, it’s always a good idea to leave a bit of room for flowers. Growing flowers alongside your vegetable plants will make your general gardening experience more enjoyable and is a great way to attract pollinators and repel garden pests! Flowers such as gaillardia, marigolds, zinnias, cosmos or nasturtiums can be sown in and around the rows of vegetables. Herbs such as dill can be very useful also. Bear in mind that some companion plants self-seed easily and can be a bit invasive (borage, chives, lemon balm etc.)
NB. Organic seeds (in French "AB" for "Agriculture Biologique") are produced from plants that aren't treated with phytosanitary products (insecticides, weed killers). The seeds do not undergo post-harvest treatment. They carry the AB label and are approved by Ecocert, an independent structure.

Botanical data
Sowing:
The germination temperature of Romanesco Cauliflower is around 15°C (minimum 7°C - maximum 20°C) and takes about 14 days.
Sowing period: from May to June
Harvest period: from August to December
You can either directly sow the seeds in the ground or prepare seedlings that will later be planted in their final position in the garden.
Preparation of seedlings: Under shelter or in a nursery in the garden for the rest of the year (according to the recommended sowing period), sow the seeds at a depth of 1 to 2 cm in a good seed compost or fine soil. Lightly cover with compost and remember to keep the substrate moist but not waterlogged.
When the young plants appear strong enough to be handled, transplant them into pots if necessary before planting them in the garden, when there is no longer any risk of frost. During planting, respect the recommended spacing for direct sowing.
Direct sowing: In properly amended and finely worked soil, make furrows about one or two centimeters deep, spaced 60 centimeters 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 centimeters.
Cultivation:
Romanesco Cauliflower is grown in full sun. It is a demanding vegetable that requires well-fertilized soil, rich in nitrogen and potassium. It is advisable to make a generous compost addition (about 3/4 kg per m2) preferably in autumn, by digging to a depth of 5 cm, after loosening the soil, as for any vegetable cultivation. 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 Dolomite or Lime.

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).
