The Enduring Appeal of Globe Artichokes in English Gardens
Globe artichokes (Cynara cardunculus var. scolymus) are more than just a culinary delight; they are a striking and historically significant plant that has graced traditional English gardens for centuries. Their architectural form, with their spiky, silver-green foliage and majestic, edible flower buds, lends a touch of regal grandeur to any herbaceous border or kitchen garden. Beyond their visual appeal, the globe artichoke represents a link to a rich horticultural past, having been cultivated in Britain since the 16th century. This article will explore the enduring appeal of globe artichokes, their historical significance, cultivation requirements, and how they continue to be a cherished element in the design and bounty of traditional English gardens.
A Royal History: Artichokes in English Horticulture
The journey of the globe artichoke to British shores is intertwined with tales of exploration, trade, and aristocratic patronage. First introduced to England in the late 1500s, likely through trade routes and continental influence, the artichoke quickly became a coveted crop among the nobility. Its exotic nature and the labor-intensive process of its cultivation made it a symbol of wealth and status. Early records suggest that Lord Protector Oliver Cromwell himself was a keen cultivator, with accounts mentioning artichokes grown at Hampton Court.
The Victorian era saw a surge in the popularity of ornamental edibles, and the globe artichoke, with its bold silhouette, was a natural fit. Garden designers and horticulturists of the period recognized its ornamental qualities, often featuring it prominently in kitchen gardens, parterres, and even as standalone specimens in more informal settings. Its silvery foliage provided a textural contrast to other greens, and the burgeoning buds offered a unique aesthetic, distinct from the more conventional flowers.
Key Historical Mentions and Cultural Significance
- Elizabethan Era Introduction: First documented cultivation in England around 1548.
- Royal Gardens: Grown in the gardens of wealthy landowners and royalty, including Hampton Court.
- Victorian Horticultural Fascination: Embraced for both its culinary use and its striking ornamental value in kitchen gardens and ornamental borders.
- Symbol of Status: Initially, its rarity and cultivation demands positioned it as a plant of prestige.
Cultivating the Globe Artichoke: A Guide for English Gardeners
Despite its somewhat exotic origins, the globe artichoke is surprisingly well-suited to the English climate, provided a few key cultivation principles are followed. Understanding its needs is crucial to unlocking its full potential, both aesthetically and gastronomically.
Site Selection and Soil Preparation
Globe artichokes thrive in a sunny position, ideally receiving at least six to eight hours of direct sunlight per day. While they appreciate warmth, they are remarkably tolerant of cooler temperatures once established. A sheltered spot, protected from strong winds, will help prevent damage to their large leaves and buds.
Soil preparation is paramount. Artichokes prefer well-drained, fertile soil that is rich in organic matter. Heavy clay soils can be improved by incorporating plenty of compost, well-rotted manure, and grit to ensure good drainage. Slightly alkaline to neutral soil pH is ideal. Before planting, dig in a generous amount of compost or aged manure to a depth of at least 30cm (12 inches).
Planting and Spacing
Globe artichokes are typically planted as young plants (often sold as bare-root or in pots) in spring, after the last risk of frost has passed. They can also be grown from seed, but this is a slower process and may not yield a harvest in the first year.
When planting, ensure adequate space for these substantial plants to develop. Mature plants can reach a height of 1.5 to 2 meters (5-7 feet) and a spread of 1 to 1.5 meters (3-5 feet). Planting them 1 to 1.5 meters (3-5 feet) apart will allow for good air circulation and prevent overcrowding. For a more ornamental effect, they can be planted as part of a mixed border, but ensure they have enough space to expand.
Watering, Feeding, and Mulching
Consistent moisture is key, especially during dry spells and when the plants are actively growing and producing buds. Water deeply at the base of the plant, avoiding wetting the leaves, which can encourage fungal diseases. Mulching around the base of the plant with compost, straw, or well-rotted manure is highly beneficial. This helps to retain soil moisture, suppress weeds, and provide a slow release of nutrients.
Feeding is also important. In early spring, apply a balanced fertilizer or a top-dressing of compost. A further feed can be given in early summer as the buds begin to form.
Overwintering and Propagation
In the UK, globe artichokes are typically perennial. However, they benefit from winter protection, especially in colder regions. After the foliage has died back, cut the stems down to about 30cm (12 inches) and mulch the base generously with straw, bracken, or compost. This protects the crown from frost.
Propagation is most commonly done by dividing established clumps in early spring. Lift the plant carefully, and separate the younger, vigorous shoots from the main crown. Replant these divisions immediately into their new positions or pots.
Key Facts and Comparison: Artichoke Varieties for the English Garden
While the classic globe artichoke is the most common, several varieties offer slightly different characteristics, making them suitable for various garden styles and culinary preferences.
| Feature | ‘Green Globe’ (Cynara cardunculus var. scolymus) | ‘Violetta’ (Cynara cardunculus var. scolymus) |
| :—————– | :———————————————————————————- | :——————————————————————————— |
| Bud Appearance | Large, green, plump buds with tightly packed bracts. | Medium-sized, deep purple-violet buds, often with hints of green. |
| Flavor Profile | Mild, buttery, with a slightly nutty undertone. | More intense, slightly sweeter flavor with a rich, earthy complexity. |
| Hardiness | Generally hardy, requiring good winter protection in colder areas. | Slightly less hardy than ‘Green Globe’, benefits from excellent winter protection. |
| Growth Habit | Vigorous, producing multiple large buds per plant. | Can be slightly more compact, often producing fewer but more intensely colored buds. |
| Ornamental Value | Striking silvery-green foliage and impressive green buds. | Beautiful dark foliage and distinct purple buds, adding color contrast. |
| Best For | Traditionalists, those seeking classic flavor, and a robust performer. | Gardeners seeking visual interest with colored buds, and a slightly more intense flavor. |
Incorporating Artichokes into Garden Design
The globe artichoke’s imposing stature and unique foliage make it a versatile plant in garden design. Its silvery-green leaves provide a welcome textural contrast, and its architectural form can anchor a border or create a focal point.
The Kitchen Garden Star
Traditionally, artichokes are a cornerstone of the English kitchen garden. Their large, impressive leaves and the promise of delicious buds make them both productive and visually appealing. They can be planted in rows or interspersed with other vegetables, their bold presence enhancing the rustic charm of the space.
Ornamental Borders and Features
Beyond the kitchen garden, artichokes can be used to great effect in ornamental borders. Planted at the back of a mixed border, their height and silvery foliage can provide a stunning backdrop for lower-growing plants. Their architectural form also makes them ideal as a solitary specimen in a lawn or as part of a Mediterranean-themed planting scheme, especially when paired with plants like lavender, rosemary, and ornamental grasses. The emerging flower buds themselves are a beautiful sight, and if allowed to mature, they develop into stunning, thistle-like purple blooms that attract pollinators.
Container Growing
For smaller gardens or those seeking to add an artichoke element without dedicating a large patch of ground, container growing is a viable option. Use a large pot (at least 45cm/18 inches in diameter and depth) with good drainage and fill it with a high-quality, well-draining potting mix. Ensure the container is placed in a sunny, sheltered spot and be mindful of watering needs, as containers can dry out more quickly.
Harvesting and Enjoying the Bounty
The reward for cultivating globe artichokes is the unique and delicious flavor of their flower buds. Harvesting at the right time is crucial for the best eating experience.
When to Harvest
Artichoke buds are ready to harvest when they have reached a good size and the outer bracts are beginning to loosen slightly, but before the flower begins to open. Typically, this occurs in early to mid-summer, about 60-80 days after the plant starts to form buds. For the most tender buds, harvest them in the morning.
To harvest, use a sharp knife or secateurs to cut the main bud stem, leaving about 2.5cm (1 inch) of stem attached. It’s also advisable to harvest some of the smaller side shoots that emerge from the leaf axils, as these are often more tender.
Preparation and Cooking Methods
The edible part of the artichoke is the fleshy base of the bracts and the heart. Before cooking, trim the thorny tips of the bracts and cut off the top third of the bud. Some gardeners also trim the stem, leaving only the base.
Artichokes can be prepared in numerous ways:
- Boiling/Steaming: The most common method. Boil or steam until tender (about 25-45 minutes depending on size), then serve with melted butter, hollandaise sauce, or a vinaigrette.
- Roasting: Halve or quarter the artichokes, toss with olive oil, herbs, and garlic, and roast until tender and slightly caramelized.
- Grilling: Similar to roasting, grilling imparts a lovely smoky flavor.
- Braising: Cook slowly in liquid (wine, stock, or water) with aromatics.
- Artichoke Hearts: Once the tough outer bracts and choke (the fuzzy center) are removed, the heart can be sautéed, marinated, or added to pasta dishes and risottos.
Troubleshooting and Potential Problems
While generally robust, globe artichokes can encounter a few issues in the English garden.
Pests and Diseases
- Aphids: These can congregate on new growth and buds. A strong jet of water or an insecticidal soap can usually manage infestations. Encouraging beneficial insects like ladybirds can also help.
- Slugs and Snails: Young plants are particularly vulnerable. Protective barriers and slug pellets can be used, though a more environmentally friendly approach is to hand-pick them or use beer traps.
- Leaf Spot: Fungal diseases can occur in wet conditions. Ensuring good air circulation and avoiding overhead watering can help prevent this.
Overwintering Success
The most common problem for UK gardeners is the failure of artichokes to survive the winter. Proper overwintering protection, as described in the cultivation section, is the most effective preventative measure.
