Artichoke Imperial Star - Cynara Scolymus
Cynara scolymus Imperial Star
Globe Artichoke
It was out of curiosity that I wanted to test growing artichokes from seeds. I was skeptical and should have refrained. I obtained a few fairly decent plants, but the fruiting was almost nonexistent and the plants completely withered, even though they are normally perennial. I won't do it again. I don't recommend it! Thankfully, I had my plants (of a different variety) purchased from a garden centre located 5 km (3.1mi) away from my place!

Description
The Imperial Star artichoke is an early and vigorous variety that produces 7 to 8 heads per plant of about 1.5 m (5ft), with a sweet and tender flavour. This perennial vegetable plant is cultivated for its round heads, about 12 cm (5in) in diameter, formed of oval, fleshy scales at the base (the leaves) and its floral receptacle, the artichoke heart. Sowing from February to March for a harvest 6 to 7 months later.
The artichoke is a perennial vegetable plant that belongs to the Asteraceae family. It belongs to the genus Cynara, like the Cardoon - and the Thistle. Known to the Greeks and the Romans since antiquity, it was introduced in France around the 15th century.
It is a plant that, although perennial, is often cultivated for two or three years. It has an upright stem that can reach a height of 2 metres (7 feet) and large, deeply cut leaves. It is its inflorescence, or rather its flower bud, which is harvested before the flower develops, that is consumed.
Coluche said of the artichoke: "It's the only dish where when you're done eating, you have more on your plate than when you started!". This is neither entirely false nor entirely true because, in the artichoke, everything is edible, or almost everything: the heart, with vinaigrette, the base of the leaves, but also the leaf stems which, when blanched, can be consumed like those of the cardoon.
The artichoke has anti-anemic, detoxifying, stimulating, and tonic properties, and contains vitamins A, B1, B2, C. It has a beneficial effect on the liver.
In the garden, the Artichoke thrives in rich and well-draining soil. As a true Mediterranean plant, its worst enemies are humidity and frost. Therefore it is best suited for mild climates and preferably grown on a mound.
Harvest and storage: The harvest of the flower buds should be done as they develop, each year. They should be harvested before the central scales spread apart and consumed as quickly as possible.
Gardener's tip: In regions with harsh winters, protect your plants with a thick layer of dry leaves. Keep a close eye on your plants as aphids love them!

Planting and care
Sowing from February to March
The seeds are sown in pots. Sow 2 or 3 seeds per pot. Keep only the best young plant for transplanting about 2 months after sowing. You will plant them in their permanent position at a distance of 80cm (32in) to 1 metre (3 feet).
In warm southern regions, you can sow directly in the ground, in holes spaced 80cm (32in) to 1m (3ft) apart.
Maintenance
Hoe and weed. Water if necessary. Mounding up the plants is beneficial as is good mulching. In October-November cut the stems that have produced flower buds, a few centimetres above the ground.

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).
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 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.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
