The Sweet Synergy: Why Companion Planting Matters for Honeyberries
Growing honeyberries (also known as Haskap) is a rewarding experience, offering delicious, antioxidant-rich fruit that ripens early in the season. To maximize the health, vigor, and yield of your honeyberry shrubs, understanding the principles of companion planting is key. This practice involves strategically planting different species together to create a mutually beneficial ecosystem. Companion planting can deter pests, attract beneficial insects, improve soil health, and even enhance the flavor of your produce.
This article delves into the world of companion flowers specifically suited for honeyberry shrubs. We’ll explore the science behind these pairings, the benefits they offer, and provide practical guidance on creating a thriving, biodiverse garden that supports your honeyberry plants.
Understanding the Needs of Honeyberry Shrubs
Before we discuss companion flowers, it’s essential to understand what honeyberry shrubs need to flourish. Honeyberries are hardy plants that generally prefer:
- Full Sun: At least 6-8 hours of direct sunlight per day.
- Well-Drained Soil: They are susceptible to root rot in waterlogged conditions.
- Slightly Acidic to Neutral pH: A soil pH between 5.5 and 7.0 is ideal.
- Consistent Moisture: Especially during fruit development, but without waterlogging.
- Pollination: Most honeyberry varieties require cross-pollination from another honeyberry plant of a different variety planted nearby.
By selecting companion flowers that share or complement these needs, we can create an environment where both the honeyberry and its floral neighbors thrive.
Key Benefits of Companion Flowers for Honeyberries
The introduction of specific flowering plants alongside your honeyberry shrubs can yield significant advantages:
Pest Deterrence
Certain flowers emit scents or possess properties that can repel common honeyberry pests like aphids, slugs, and certain beetles. By creating a natural defense system, you reduce the reliance on chemical pesticides, promoting a healthier garden and fruit.
Attracting Beneficial Insects
Many flowering plants act as magnets for pollinators (bees, butterflies) and predatory insects (ladybugs, lacewings, hoverflies).
- Pollinators: While honeyberries are largely wind-pollinated, increased pollinator activity in the vicinity can still contribute to overall plant health and fruit set.
- Predatory Insects: Ladybugs, lacewings, and hoverflies are voracious eaters of aphids and other small, soft-bodied pests that can plague honeyberry plants.
Soil Health Improvement
Some companion plants have deep taproots that break up compacted soil, allowing for better aeration and water penetration to the honeyberry’s roots. Others are nitrogen-fixers, a vital nutrient for plant growth, enriching the soil naturally.
Weed Suppression
A dense carpet of ground cover or low-growing flowers can help suppress weed growth by outcompeting them for sunlight, water, and nutrients.
Aesthetic Appeal
Beyond the practical benefits, companion flowers add vibrant color and texture to your garden, transforming the space into a more visually appealing and enjoyable environment.
Top Companion Flower Choices for Honeyberries
When selecting companion flowers, consider their growth habits, bloom times, and specific benefits they offer. Here are some excellent choices:
1. Lavender (Lavandula spp.)
Lavender is a perennial favorite for a reason. Its fragrant purple blooms are not only beautiful but also incredibly beneficial.
- Pest Repellent: The strong scent of lavender is known to deter aphids, slugs, and other common garden pests.
- Attracts Pollinators: Bees and butterflies are drawn to lavender, increasing general pollinator activity in your garden.
- Drought Tolerant: Once established, lavender requires minimal watering, making it a good partner for honeyberries that appreciate consistent, but not excessive, moisture.
- Soil Preference: Thrives in well-drained soil and prefers a sunny location, aligning perfectly with honeyberry needs.
2. Borage (Borago officinalis)
Borage is an annual herb with charming star-shaped blue flowers. It’s a true superstar in the world of companion planting.
- Attracts Pollinators: Borage is a powerful bee attractant, vital for a healthy garden ecosystem.
- Improves Soil: Its deep taproot mines nutrients from deeper soil layers, making them available to shallow-rooted plants when the borage decomposes. It’s also said to improve the flavor of strawberries, and could potentially benefit honeyberries in a similar way.
- Repels Pests: Can deter tomato hornworms and cabbage worms.
- Self-Seeding: Often self-seeds, meaning you can enjoy it year after year with minimal effort.
3. Marigolds (Tagetes spp.)
These cheerful, brightly colored flowers are a staple in many organic gardens.
- Nematode Repellent: Certain varieties, particularly French marigolds (Tagetes patula), are known to release compounds from their roots that can deter soil nematodes, microscopic worms that can damage plant roots.
- Repels Other Pests: Their scent can also deter other flying insects like whiteflies and aphids.
- Attracts Pollinators: Bees and hoverflies are attracted to marigolds.
- Hardy: Relatively easy to grow and tolerant of various soil conditions as long as they are well-drained.
4. Nasturtiums (Tropaeolum spp.)
Nasturtiums are not only beautiful but also functional, serving as a “trap crop.”
- Trap Crop: Aphids are particularly attracted to nasturtiums. By planting them nearby, you can lure aphids away from your honeyberry shrubs, concentrating them on the nasturtiums where they are easier to manage or where natural predators can find them.
- Edible: Both the flowers and leaves are edible, adding a peppery kick to salads.
- Attracts Pollinators: Bees are drawn to their vibrant blooms.
- Easy to Grow: They prefer poor to moderately fertile, well-drained soil and full sun to partial shade.

Also known as pot marigold, calendula offers sunny, daisy-like flowers.
- Attracts Beneficial Insects: Ladybugs, lacewings, and hoverflies are attracted to calendula, helping to control aphid populations.
- Repels Pests: Can deter whiteflies and some types of beetles.
- Edible: The petals are edible and have medicinal properties.
- Self-Seeding: Readily self-seeds, ensuring a continuous presence.
6. Yarrow (Achillea millefolium)
Yarrow is a hardy perennial with flat-topped clusters of flowers.
- Attracts Beneficial Insects: Its flowers are a magnet for ladybugs, lacewings, hoverflies, and parasitic wasps, all of which help control pest populations.
- Improves Soil: Its deep taproot helps break up compacted soil and draws up minerals.
- Drought Tolerant: Once established, it is very drought-tolerant.
- Aesthetic Appeal: Adds a feathery texture and a long bloom season to the garden.
7. Comfrey (Symphytum officinale)
While not strictly a “flower” in the ornamental sense, comfrey’s blooms are attractive to pollinators, and its benefits are substantial.
- Dynamic Accumulator: Comfrey is renowned for its ability to draw up nutrients, particularly potassium and nitrogen, from deep within the soil. Chopped leaves can be used as a nutrient-rich mulch or “chop-and-drop” fertilizer around honeyberry plants.
- Attracts Pollinators: Its bell-shaped flowers are a favorite of bees and other pollinators.
- Improves Soil Structure: Its extensive root system helps break up heavy clay soils.
- Caution: Comfrey can spread aggressively by rhizomes, so consider planting it in a contained area or where its spread is manageable.

Designing Your Honeyberry Garden: Planting Strategies
The placement of your companion flowers is as important as the choice of flowers themselves. Aim for a naturalistic approach rather than rigid rows.
Interplanting
Plant smaller flowering plants directly around the base of the honeyberry shrubs. Ensure you leave some space around the immediate trunk to avoid moisture buildup and potential rot. This allows the flowers to benefit from the shade during the hottest parts of the day while still receiving adequate light.
Creating a Border
Plant a border of taller, more robust flowers like yarrow or lavender along the edges of your honeyberry patch. This can create a visual barrier and attract beneficial insects from a wider area.
Successional Planting
To ensure continuous blooms and benefits throughout the growing season, consider successional planting. Mix early bloomers (like calendula) with mid-season flowers (like lavender and borage) and late bloomers (like marigolds and nasturtiums).
