The Imperial Star artichoke, with its striking purple bracts and delicious heart, is a culinary gem that can add a touch of elegance and flavor to your garden. But don’t be intimidated by its exotic appearance – learning how to grow Imperial Star artichokes is surprisingly simple. This comprehensive guide will walk you through every step, from choosing the right location to harvesting your own succulent artichoke hearts.
Understanding the Imperial Star Artichoke
The Imperial Star artichoke (Cynara cardunculus) is a perennial plant that produces large, edible flower buds. Its unique, star-shaped bracts, which resemble scales, are what give it its distinctive name. This variety is known for its exceptional flavor and size, making it a popular choice for both home gardeners and commercial growers.
Choosing the Right Location
Imperial Star artichokes thrive in sunny, well-drained locations. They prefer a soil pH between 6.0 and 7.0, but can tolerate slightly acidic conditions. Avoid planting them in areas prone to frost or cold winds, as they are susceptible to damage.
Preparing the Soil
Before planting, amend the soil with compost or well-rotted manure to improve drainage and fertility. This will provide the artichokes with the nutrients they need for healthy growth. Dig a hole twice the width and depth of the artichoke’s root ball, and gently loosen the soil at the bottom.
Planting Your Imperial Star Artichokes
The best time to plant artichokes is in the spring, after the last frost has passed. You can start them from seed or purchase young plants from a nursery.
- From seed: Sow seeds indoors 6-8 weeks before the last frost. Transplant seedlings outdoors when they are 6-8 inches tall.
- From plants: Plant artichoke plants 3-4 feet apart in rows. Gently remove the plant from its container, loosen the roots, and place it in the prepared hole. Backfill with soil and water thoroughly.
Providing Water and Nutrients
Imperial Star artichokes require regular watering, especially during dry periods. Aim to water deeply once a week, allowing the soil to dry slightly between waterings. During the growing season, fertilize your plants every 4-6 weeks with a balanced fertilizer.
Protecting Your Plants from Pests and Diseases
Artichoke plants are relatively pest-resistant, but they can be susceptible to certain problems. Here are some common issues and how to address them:
- Aphids: These small insects can suck sap from the plants, causing damage. Control them with insecticidal soap or by introducing beneficial insects like ladybugs.
- Caterpillars: Caterpillars can chew on the leaves and buds. Handpick them off or use a Bacillus thuringiensis (Bt) spray.
- Botrytis blight: This fungal disease can cause gray mold on the leaves and buds. Avoid overcrowding plants and provide good air circulation to prevent its spread.
Harvesting Your Imperial Star Artichokes
The best time to harvest artichokes is when the buds are firm and tightly closed, but before the bracts start to open. To harvest, cut the bud at the base with a sharp knife.
Enjoying Your Harvest
Once harvested, artichokes can be stored in the refrigerator for up to a week. To prepare them for cooking, trim the tough outer bracts and the top portion of the bud. Steam, boil, or roast artichokes until tender.
A New Season of Growth: Winter Care
Imperial Star artichokes are perennial plants, meaning they live for several years. In colder climates, they may die back to the ground during the winter, but will regrow in the spring. To ensure their survival, mulch the base of the plants with a thick layer of straw or leaves before winter.
The End of the Journey: Dividing Your Plants
As artichoke plants mature, they can become overcrowded. To rejuvenate the plants and encourage new growth, you can divide them every 3-4 years. Simply dig up the plant and carefully separate the roots into smaller clumps, each with a few stems. Replant the divisions in new locations.
