More information

An early and vigorous variety that produces 7 to 8 round heads on each stalk of about 1.5 m (5ft) in height, with a sweet and tender flavour. This perennial vegetable plant is cultivated for its round heads, about 12cm (5in) in diameter, composed of ovate scales with a slight point, fleshy at the base (the leaves), and for its floral receptacle, the artichoke heart. Plant it in spring, or in autumn if your winters are mild, and harvest from May to August, for about 4 years.

Description

The Imperial Star artichoke is an early globe-type variety with vigorous growth. Each plant forms a beautiful clump reaching about 1.50m (5ft) in height and 1m (3ft) in width and produces round, green heads measuring approximately 12cm (5in) in diameter, with a sweet and tender flavour of excellent quality. Plants produce 3 to 4 artichokes in the first year and 6 to 8 in subsequent years. Plant the young plants in spring, or autumn if your winters are mild, and harvest from May to August for about 4 years. The plug plants are planted from April to June after the last frost, when the plants have several leaves.

Certified organic plants.

The artichoke, scientifically known as Cynara scolymus, has large, deeply cut, silvery-grey leaves. At the end of the stems green or purple heads form, which can be consumed raw or cooked depending on the variety. If you let them bloom, you will get very decorative blue-violet flowers. Thus, the artichoke can be grown both in the vegetable garden and in the garden as an ornamental plant. By protecting the base during winter, you can harvest artichokes for several years. In cooking it is the base of the bracts that is consumed, as well as the flower receptacle, often called the heart of the artichoke. Some varieties can be eaten raw when the heads are small, but most artichokes require cooking, usually by steaming.

Harvesting : From May to August. The heads are harvested before flowering when they are perfectly formed, with the lower bracts starting to open. Cut cleanly with a knife or secateurs about 10 cm (4in) from the stem.

Storage : Artichokes should be consumed quickly after harvest. You can also can them or freeze them.

Gardener's tip : Since artichokes are a nutrient-demanding vegetable, they are ideally planted after a crop of peas, beans, or broad beans. These belong to the Fabaceae family and enrich the soil with nitrogen. Also, since artichoke growth is relatively slow, you can plant short-cycle plants like lettuces nearby.

Planting and care

The artichoke thrives in deep, humus-rich, moist, and well-drained soil. It should be planted in a sunny location if possible. A significant amount of well-rotted compost should be added the previous autumn, by scratching it into the ground to a depth of 5cm (2in) after working the soil. Planting takes place in spring, in March-April, or in autumn, in September-October, for regions with mild winters.

Dig a hole (3 times the volume of the root ball), insert the root ball and cover with soil. Firmly press down and water to keep the soil moist. Space the plants 1m (3ft) apart in all directions. Water regularly at the base, but moderately to avoid root rot.

Before the frost, cut the stems that have produced artichokes at ground level, then cut the main leaves in half. Add well-rotted compost every year in autumn.

Hardy down to -5°C (23°F), the artichoke needs to be protected before the first frost. Mound soil around the base, covering it to a height of 20 to 30 cm (8 to 12in), then cover with a layer of straw or dead leaves. Remove the mulch in February and remove the mound of soil in March.

The harvest decreases after 3 to 4 years, so it is preferable to replant new artichoke plants.
