Description
The 'Summer Purple' broccoli is a variety from Colombia with purple florets well adapted to summer cultivation. Robust and vigorous, this Broccoli tolerates heat very well and can be harvested over a long period. Sow from March to June for a harvest from July to November.
Offering beautiful firm florets, primarily green but sometimes purplish or white, the Broccoli, commonly called Broccoli, is a vegetable whose flowers are consumed just before they bloom. It belongs to the large family of Brassicaceae (formerly Cruciferae) and bears the Latin name Brassica oleracea italica.
Although introduced to France by Catherine de Medici under the name "Italian Asparagus," Broccoli has only been cultivated on a large scale since the 1980s.
Originally from southern Italy, this cabbage, with its mild flavour, is now highly appreciated as it lends itself to many preparations. It is best consumed quickly, steamed, and then prepared in various ways: quickly sautéed, gratinéed, in quiches, mashed, in soups, etc. It is a low-calorie vegetable and rich in vitamin C.
Like almost all cabbages (Brussels sprouts being the exception), Broccoli is a demanding vegetable that requires excellent fertiliser and regular moisture.
Harvest: Broccoli is harvested by cutting, with a knife, in two stages: first, the terminal floret, then the lateral florets.
Storage: Broccoli 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: In recent years, the Cabbage Fly (Contarinia nasturtii), a small winged, piercing and sucking fly, has been causing havoc on Broccoli in certain regions. We recommend prevention by installing insect-proof netting on market garden hoops throughout the flight period, from mid-May to mid-July. These nets are easy to set up and reusable to protect, for example, your carrot and leek crops.

Planting and care
Sowing:
The germination temperature of the 'Summer Purple' Broccoli is around 15°C (59°F) and takes about 14 days.
It is sown from March to June for a harvest from July to November.
You can proceed with direct sowing in place or prepare seedlings that will later be planted in their final position in the garden.
Preparing seedlings: at home, in a heated greenhouse from late autumn to late spring, or in a cold greenhouse for the rest of the year, sow the Broccoli seeds at a depth of 1 cm (0in) in good seed compost. Lightly cover with compost or vermiculite. 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 a heated greenhouse, gradually acclimatise them to cooler temperatures before transplanting them into the garden when there is no longer any risk of frost.
Direct sowing: In suitably amended and finely worked soil, make furrows about one centimetre deep, spaced 50 to 60 cm (20 to 24in) apart. Sow the seeds and cover them with a thin layer of fine soil. When the seedlings are well developed, thin them out by keeping only one plant every 50 cm (20in).
Cultivation:
Broccoli is a demanding vegetable that requires well-fertilised soil and is rich in nitrogen and potassium. Applying a generous amount of mature compost (about 3/4 kg per m2) is recommended by scratching it into the soil to a depth of 5 cm (2in), preferably in autumn, after loosening the soil as you would for any vegetable crop. 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.
Broccoli, like all cabbage plants, is quite susceptible to diseases such as Clubroot and pests (Cabbage White Butterfly, Cabbage Fly, Flea Beetle, Leafminer...), so this crop needs to practice crop rotation.
It is beneficial to associate broccoli with many vegetables, such as tomatoes and lettuce. But avoid planting it near other Brassica, aubergine, fennel, lamb's lettuce, leeks and strawberries.

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.
