À propos Globe artichoke
We have been successfully growing Globe artichokes for 20 years. After trying several cultivars, we chose this one because it produces vigorous and productive plants. The plants must be exposed to frost in May to induce flowering in the first year. A rewarding crop.
Conventionally produced seeds.
Here is an explanation from the book La culture écologique des plantes légumières by Yves Gagnon:
“Sow seeds in a tray in germinating soil at a rate of 1 seed every 5 cm, covering them with 2 cm of soil. Once the first true leaves have emerged, transplant the seedlings into growing soil in pots 10 to 12 cm in diameter. To force flowering, expose the young plants to light frosts. This is a form of acclimatization that acts as stratification. The plants are frost-resistant but register the stress that will induce early flowering. Transplant the plants to the garden 2 to 3 weeks before the last frost.”

To succeed with your artichoke plants
As modern artichokes are not programmed to produce flower buds in their first year, to force flowering, young plants must be exposed to a few light frosts. This is a form of acclimatization that acts as stratification. The plants resist frost, but register the stress which will induce early flowering. The plants are transplanted into the garden 2 to 3 weeks before the last frost.

Artichoke growing conditions
In temperate climates, such as the Mediterranean or Brittany, artichokes are grown as perennials. They produce for two or three years after the year of planting. In more northern regions, where winters are harsh, they are grown as annuals; they should then be sown indoors at the beginning of March.
Artichokes thrive in warm, humid conditions and require full sunlight. They prefer deep, well-loosened soils rich in organic matter. Artichokes require abundant fertilization with young compost at a rate of 1 to 1.5 t/100 m2. The soil should remain moist, but not excessively so. The optimal pH for growing them is between 6 and 7.
Crop rotation
Grown as an annual, the artichoke comes first in the rotation, ideally after a green manure. Grown as a perennial, it should be given a separate place in the garden.
Artichoke Companionship
Since artichokes require a lot of space, in the spring, when the plants are young, you can grow various leafy vegetables between their rows. To prevent aphids, you can plant them with nasturtiums. Marigolds are also a good companion. Finally, white clover can be planted between the plants as an intercrop.
