The Buzzworthy Beauty: Cultivating a Pollinator Paradise Around Globe Artichokes
Globe artichokes (Cynara cardunculus var. scolymus) are not just a culinary delight; they are also a magnet for pollinators. Their striking thistle-like flowers, bursting with nectar and pollen, provide a valuable food source for a wide array of beneficial insects. To maximize the appeal of your artichoke patch and foster a truly thriving ecosystem, thoughtful companion planting is key. This article explores the best plant pairings for globe artichokes, focusing on their ability to attract and support pollinators, while also considering other beneficial gardening principles.
Understanding the Pollinator Needs of Globe Artichokes
Globe artichokes are open-pollinated plants, meaning they rely on external agents, primarily insects, for pollination. While they can self-pollinate to some extent, cross-pollination leads to more robust seed production and healthier plants. The large, complex flower heads are particularly attractive to bees, including bumblebees, honeybees, and solitary bees. Butterflies and other nectar-feeding insects also frequent these blooms.
To support this crucial pollination process, we need to provide a continuous and diverse food source throughout the growing season, not just when the artichokes are in full bloom. This involves selecting companion plants that bloom at different times, offer complementary nutritional profiles, and attract a wider spectrum of pollinators.
Key Principles for Companion Planting with Globe Artichokes
When selecting companions for your globe artichokes, several principles should guide your choices:
- Pollinator Attraction: The primary goal is to draw in a diverse range of pollinators. This means choosing plants with high nectar and pollen production.
- Successional Blooming: Aim for plants that bloom before, during, and after the main artichoke flowering period to ensure a consistent food supply.
- Habitat and Shelter: Some companion plants can provide shelter or nesting sites for beneficial insects.
- Pest Deterrence: Certain herbs and flowers have natural pest-repelling properties that can protect your artichokes.
- Soil Improvement: Leguminous plants can fix nitrogen in the soil, benefiting artichokes.
- Visual Appeal: While functionality is key, a beautiful garden is also a joy to behold!
Top Pollinator-Attracting Companion Plants for Globe Artichokes
Let’s delve into specific plants that create a symbiotic relationship with globe artichokes, enhancing the pollinator-friendliness of your garden.
Herbs: The Aromatic Allies
Many culinary herbs are not only useful in the kitchen but are also exceptional for attracting pollinators, especially when allowed to flower.
Lavender (Lavandula spp.)
Lavender is a classic pollinator magnet. Its fragrant spikes are irresistible to bees, especially honeybees and bumblebees. Planting lavender around your artichokes provides an early-season nectar source, with many varieties blooming concurrently with or just before artichokes. Its drought tolerance also makes it a low-maintenance companion.
Rosemary (Rosmarinus officinalis)
Rosemary produces small, often blue, flowers that are a favorite among bees. It blooms prolifically, often from spring through fall, offering a continuous food source. Rosemary also has a reputation for deterring certain pests, such as cabbage moths, which can sometimes bother artichokes.
Thyme (Thymus spp.)
Low-growing thyme varieties, when allowed to flower, create a carpet of tiny blooms that attract smaller pollinators like hoverflies and native bees. Thyme also acts as a living mulch, helping to retain soil moisture and suppress weeds.
Oregano (Origanum vulgare)
The prolific small flowers of oregano are a significant draw for bees and butterflies. It blooms throughout the summer and can act as a ground cover, suppressing weeds and improving soil health.
Borage (Borago officinalis)
Borage is a stellar companion for many vegetables. Its star-shaped blue flowers are a favorite of honeybees, and it’s known for attracting them in droves. Borage also reseeds readily, ensuring a continuous presence in the garden.
Flowers: The Vibrant Visuals and Nectar Havens
Incorporating a variety of flowering plants will create a multi-layered pollinator buffet.
Marigolds (Tagetes spp.)
Certain varieties of marigolds, particularly those with single-petal blooms (like French marigolds), are excellent at attracting pollinators and are also known for their ability to deter nematodes in the soil. They provide a burst of color throughout the summer.
Cosmos (Cosmos bipinnatus)
The delicate, daisy-like flowers of cosmos are a beacon for butterflies and bees. They bloom from mid-summer until frost, providing a long season of nectar. Cosmos are easy to grow from seed and add an airy beauty to the garden.
Sunflowers (Helianthus annuus)
While sunflowers are taller and might require slightly more space, their large flower heads are packed with pollen and nectar, drawing in a wide variety of bees and other beneficial insects. Planting smaller varieties as a border can be very effective.
Zinnias (Zinnia elegans)
Zinnias are renowned for attracting butterflies and bees with their bright, abundant blooms. They come in a wide range of colors and sizes, offering continuous flowering from summer until the first frost.
Nasturtiums (Tropaeolum majus)
Nasturtiums are versatile plants. Their brightly colored flowers attract pollinators, and their peppery leaves and flowers are edible. They can also act as a trap crop for aphids, luring them away from your artichokes.
Echinacea (Coneflower) (Echinacea purpurea)
Coneflowers are incredibly beneficial for a wide range of pollinators, especially bees and butterflies. They are also drought-tolerant and attract beneficial predatory insects like lacewings when they go to seed.
Vegetables: The Functional Friends
Some vegetables, when allowed to bolt and flower, can also contribute to a pollinator-friendly environment.
Leafy Greens (e.g., Kale, Lettuce, Spinach)
While we usually harvest leafy greens before they flower, allowing some to bolt in the spring or fall will produce small, nectar-rich flowers that attract early and late-season pollinators. This is particularly useful for providing resources when other plants are not in bloom.
Brassicas (e.g., Broccoli, Cabbage)
Similar to leafy greens, brassicas will send up flowering stalks with small yellow flowers that are very attractive to beneficial insects. Letting a few plants go to seed provides a valuable nectar source.
Carrots and Parsnips (Daucus carota, Pastinaca sativa)
When allowed to overwinter and bolt in their second year, carrots and parsnips produce umbelliferous flowers. These are particularly attractive to beneficial insects like hoverflies, parasitic wasps, and small solitary bees.
