The Imperial Star Artichoke is a perennial plant that’s not only known for its delicious taste but also its ornamental beauty. This variety of artichoke is particularly popular due to its tolerance to both cold and hot climates, making it a great choice for gardeners across different regions. But how exactly do you plant Imperial Star Artichokes? What are the best patterns and spacing techniques to ensure a bountiful harvest? Let’s dive in and explore.
Understanding the Imperial Star Artichoke
The Imperial Star Artichoke, scientifically known as Cynara scolymus, is a variety that’s been bred for its ability to produce a high yield in a single season. According to the USDA, it’s a variety that’s particularly well-suited to annual cultivation, unlike some other artichoke varieties that require biennial cultivation.
Imperial Star Artichokes are known for their large, fleshy, and flavorful hearts. They typically produce about six to eight mature buds per plant in a season. As an added bonus, the plant itself is quite attractive, with large, silvery-green leaves that can add a touch of beauty to any garden.
Preparing the Soil
Like most plants, Imperial Star Artichokes thrive in well-prepared soil. The USDA recommends a sandy or loamy soil with a pH between 6.5 and 8.0. This type of soil ensures good drainage, which is crucial for preventing root rot and other diseases.
Before planting, it’s a good idea to enrich the soil with organic matter such as compost or well-rotted manure. This not only improves soil fertility but also enhances its water-holding capacity, which is particularly important for artichokes as they require consistent moisture for optimal growth.

When to Plant
Timing is crucial when it comes to planting Imperial Star Artichokes. According to the USDA, the best time to plant is in early spring, as soon as the soil can be worked. This gives the plants enough time to mature and produce buds before the first frost in fall.
However, in regions with mild winters, you can also plant in late fall for a spring harvest. This allows the plants to establish themselves over the winter and start producing buds as soon as the weather warms up.
How to Plant
- Start by digging a hole that’s about 6 inches deep and 12 inches wide.
- Place the artichoke seedling in the hole, making sure the top of the root ball is level with the soil surface.
- Backfill the hole with soil, firming it gently around the base of the plant.
- Water thoroughly after planting.
Patterns and Spacing
Proper spacing is crucial when planting Imperial Star Artichokes. These plants can grow quite large, with some reaching up to 4 feet in height and spread. Therefore, to ensure each plant has enough space to grow and thrive, it’s recommended to space them about 3 to 4 feet apart.
As for the planting pattern, a square or diamond pattern is often recommended. This allows for efficient use of space and makes it easier to navigate between plants for maintenance and harvesting.
Caring for Your Imperial Star Artichokes
Once your artichokes are planted, they’ll need regular care to ensure a healthy, productive crop. This includes regular watering, feeding, and pest control.
Artichokes require consistent moisture, especially during dry periods. A layer of mulch around the base of the plants can help retain soil moisture and suppress weeds. As for feeding, a balanced vegetable fertilizer applied according to package instructions should suffice.
Pests such as aphids and artichoke plume moths can be a problem. Regular inspections and prompt action at the first sign of infestation can help keep these pests in check.
Harvesting Your Imperial Star Artichokes
Imperial Star Artichokes are typically ready for harvest about 85 to 100 days after planting. The buds are harvested when they are still closed and firm to the touch. If allowed to open, the buds become flower-like and are no longer edible.
Harvesting is as simple as cutting the stem about 1 to 3 inches below the bud. After harvesting, the plants will continue to produce smaller buds that can also be harvested and enjoyed.
Conclusion
Planting Imperial Star Artichokes can be a rewarding experience, both for the delicious harvest and the ornamental value they add to your garden. With the right preparation, planting techniques, and care, you can enjoy a bountiful crop of this tasty and versatile vegetable.
