The globe artichoke, a perennial member of the thistle family, boasts elongated, silver-green leaves that resemble the graceful fronds of a giant fern. Delve into the realm of planting, tending, and harvesting these delectable edibles right in your own garden!

Discovering Artichokes

The blossoming buds, better known as the prized “artichokes” we gather and savor, take on a thistle-like appearance with their striking violet hues when allowed to mature. These towering plants offer versatility, thriving when organized into rows for a structured garden layout, serving as informal hedging, or even gracing wide borders. With potential heights ranging between 3 to 5 feet, artichokes stand as impressive botanical entities.

Thriving in cool and humid summers accompanied by mild winters, artichokes reveal their preference for specific climates. In areas with cooler temperatures, it’s advisable to treat the artichoke as an annual, renewing the planting process regularly.

Artichoke Flowers

A solitary plant yields a bountiful harvest of artichokes. While the largest bud proudly crowns the apex of the plant, numerous smaller buds flourish beneath, enhancing the overall yield of these culinary delights.

Planting Artichokes

Choosing the Perfect Spot

Select a prime location within your garden that receives ample sunlight, ensuring a minimum of 6-8 hours of direct sunlight each day. This sunlight exposure is crucial for optimal growth.

Artichokes are known to be voracious consumers of nutrients. For every individual plant, enrich the soil by incorporating a spade’s worth of compost or aged manure prior to planting. While these plants crave consistent moisture, they shy away from waterlogged conditions.

Strategic Planting Times

Artichokes present various avenues for cultivation, including seeds, rooted shoots from established plants, or dormant roots.

When beginning from seeds:

  • Initiate the process indoors during late winter or the onset of spring, approximately 8-10 weeks prior to outdoor planting.
  • Prior to sowing in trays or pots, indulge the seeds in a warm water soak.
  • Position the trays or pots in a warm location infused with bright, natural light.
  • Ensure the soil remains consistently moist throughout the germination phase.

For planting seedlings and shoots in the garden, the ideal time is during the spring season, post the final frost of winter.

In regions that remain frost-free, dormant roots can be introduced into the soil during fall or winter. In contrast, areas with cooler climates should wait until spring post the last frost to accommodate the dormant roots.

Planting Methodology

  • Allocate a space of three to four feet between each plant within rows, and maintain a spacing of four to five feet between the rows.
  • When planting shoots and dormant roots, aim for a depth of approximately six inches. Keep in mind that the tops of these plant components should remain above ground level.
  • A thorough watering session at the time of planting is essential to provide a nurturing start to the artichokes’ growth journey.

Cultivating Artichokes: The Growth Process

  • Ensure consistent soil moisture, as artichokes thrive on ample water supply, which is crucial for the development of their delectable buds.
  • Employ mulching to retain soil moisture, creating an environment conducive to artichoke growth.
  • Administer a balanced organic fertilizer on a monthly basis throughout the growth season.
  • As the plants begin to bud, replace the mulch with a layer of compost to cover the soil around them.
  • Artichoke plants enter a dormant phase during hot weather, resuming growth as temperatures cool in late summer and fall. A potential second harvest might emerge during this period.
  • In colder regions, post-fall harvest, trim the plants back to around 6 inches and shield the plant crowns with leaves.
  • Elevate winter protection by adding about a foot of straw on top.
  • With the arrival of spring and the passing of the last frost, remove the straw and leaves.
Fresh Artichokes Growing

Artichoke Propagation: A How-To

  • Handpick robust shoots from an established plant that demonstrated excellent yield the previous year.
  • Spring marks the opportune moment for removing shoots, ideally when they attain a height of approximately 8 inches.
  • Employ a precise cut below the soil’s surface, severing the shoot from the mother plant at its root ball attachment point.
  • Gently detach the roots connected to the shoot from the root ball.
  • The newly detached shoot can be introduced to a fresh planting spot or generously shared among gardening companions for propagation endeavors.

Optimal Varieties for Your Garden

  • ‘Green Globe’: This early-maturing gem suits northern gardeners well and can be cultivated as an annual.
  • ‘Violetto’: Showcasing purple, slightly elongated buds, this variety flourishes as a perennial.
  • ‘Imperial Star’: Delivering delectable round buds that mature ahead of schedule, this annual variety impresses by yielding robust artichokes in its first year from seed. The plants stand around 3 feet tall, bearing 1-2 primary buds and 5-7 smaller secondary buds.
  • ‘Emerald’: Featuring thornless buds, this remarkably productive option adorns glossy, deep green buds atop 4 to 5 feet tall plants. It thrives as a perennial in zones 7 and above.

Harvesting Artichokes: A Delicate Procedure

  • The opportune time to harvest artichoke buds is when they’ve plumped up but remain tightly closed.
  • Utilize a sharp knife to make a clean cut across the stem, approximately 1 to 2 inches beneath the bud.

Proper Artichoke Storage Methods

  • For immediate freshness, sprinkle water on freshly harvested artichokes and place them within a plastic bag. Refrigeration sustains their quality for up to 2 weeks.
  • Should you opt to freeze artichoke hearts, begin by blanching them in boiling water along with a dash of lemon juice for 1-2 minutes. Subsequently, allow the hearts to cool and dry prior to packing them into plastic freezer bags.

Culinary Tips for Artichokes

Artichokes offer delightful flavors whether enjoyed in their raw state, cooked form, or even as pickled or canned treats.

Culinary Tips for Artichokes

Prior to embarking on the cooking journey, initiate preparations by trimming the stem’s base and removing any resilient outer leaves. A trim of approximately 1 inch from the artichoke’s spiky apex is also recommended.

When it comes to the cooking process, opt for steaming over boiling. This method ensures that artichokes are cooked to perfection, maintaining the ideal moisture balance for a delectable outcome.
