Honeyberry shrub companion flowers for pollination

The Sweet Synergy: Why Companion Planting Matters for Honeyberries

Honeyberry (also known as Haskap) shrubs are a fantastic addition to any garden, offering early-blooming flowers and delicious, nutrient-rich berries. To maximize your honeyberry harvest and overall plant health, understanding the principles of companion planting is key. Companion planting involves strategically placing different plant species together to create a mutually beneficial environment. This can involve attracting pollinators, deterring pests, improving soil health, and enhancing nutrient uptake. For honeyberries, the most crucial aspect of companion planting revolves around ensuring effective pollination.

While honeyberries are self-pollinating to some extent, their fruit set and berry size are significantly improved when cross-pollinated by another honeyberry variety. However, attracting a broader range of pollinators, including bees and other beneficial insects, can further boost your yields and overall plant vigor. This is where companion flowers come into play. By planting flowers that bloom concurrently with your honeyberries or that attract pollinators during the honeyberry’s flowering period, you create a more vibrant ecosystem that benefits your honeyberry shrubs.

Understanding Honeyberry Pollination Needs

Honeyberries are among the earliest blooming plants in many temperate climates, often flowering in late winter or early spring, sometimes even before the last frosts have disappeared. This early bloom makes them vulnerable to insufficient pollinator activity if other nectar and pollen sources are scarce.

Honeyberries have a unique pollination mechanism. They are entomophilous, meaning they rely on insects for pollination, primarily bees. For successful fruit set, pollen from one honeyberry cultivar needs to be transferred to the flower of a different cultivar. However, the presence of generalist pollinators, even if they aren’t specifically honeyberry pollinators, can still be beneficial. They increase overall pollinator traffic in the garden, indirectly increasing the chances of cross-pollination occurring. Furthermore, these companion flowers can act as a “food base” for pollinators, ensuring their presence in your garden during the critical honeyberry flowering window.

Key Characteristics of Ideal Honeyberry Companion Flowers

When selecting companion flowers for your honeyberries, several factors should be considered to ensure they truly benefit your honeyberry shrubs:

• Bloom Time: The most critical factor is bloom time. Companion flowers should ideally bloom at the same time or slightly before the honeyberries to attract pollinators early.
• Pollinator Attraction: Flowers that are known to attract bees, hoverflies, and other beneficial insects are paramount. Look for species with open, easily accessible flowers that provide abundant nectar and pollen.
• Growth Habit: The companion plant’s size and growth habit should complement the honeyberry shrub without overwhelming it. Low-growing, spreading plants can act as a living mulch, while taller, slender plants can provide vertical interest.
• Soil and Light Requirements: Ideally, companion flowers should share similar preferences for soil type, pH, and sunlight exposure as honeyberries. Most honeyberries thrive in full sun to partial shade and well-drained, slightly acidic soil.
• Pest Deterrence: Some companion plants have natural pest-repelling properties, which can further protect your honeyberry shrubs.
• Aesthetic Appeal: While functionality is key, don’t overlook the visual appeal. A mix of colors and textures can make your garden a more beautiful and enjoyable space.

Top Companion Flower Picks for Honeyberry Pollination

Here are some excellent companion flower choices that align with the needs of honeyberry shrubs:

Early Spring Bloomers (Crucial for Honeyberry Pollination)

These flowers kickstart the pollinator season, ensuring a consistent presence of bees when honeyberries are in bloom.

• Forget-Me-Nots (Myosotis spp.): These delicate blue flowers are among the earliest bloomers. They are magnets for early emerging bees and provide a beautiful carpet of color beneath your honeyberries. They prefer moist, well-drained soil and partial shade.
• Primroses (Primula spp.): Available in a wide array of colors, primroses offer early nectar and pollen. They thrive in shady, moist conditions, making them a good underplanting for honeyberries that receive some afternoon shade.
• Violas and Pansies (Viola spp.): Hardy varieties of violas and pansies can tolerate light frost and bloom in early spring. Their cheerful faces attract small bees and hoverflies. They prefer cooler temperatures and moist soil.
• Creeping Phlox (Phlox subulata): This low-growing, mat-forming phlox blooms prolifically in early to mid-spring with a carpet of pink, purple, or white flowers. It attracts bees and tolerates full sun and well-drained soil, making it a great ground cover for honeyberry beds.
• Lungwort (Pulmonaria spp.): Lungwort offers attractive foliage and bell-shaped flowers that change color as they mature, providing nectar for early bees. It prefers shady, moist environments.

Mid-Spring Bloomers (Sustaining Pollinator Activity)

As honeyberries continue to flower, these plants provide a continuous food source for emerging pollinators.

• Borage (Borago officinalis): This easy-to-grow annual is a powerhouse for bees. Its star-shaped blue flowers are rich in nectar and pollen, and it blooms from spring until frost. Borage self-seeds readily and prefers full sun.
• Comfrey (Symphytum officinale): While often grown for its medicinal properties and as a compost activator, comfrey also produces abundant nectar-rich flowers that are a favorite of bumblebees. It’s a robust perennial that thrives in full sun to partial shade.
• Bleeding Hearts (Dicentra spectabilis): These classic shade garden plants offer unique, heart-shaped flowers in spring, attracting bees. They prefer moist, well-drained soil and partial to full shade.
• Columbine (Aquilegia spp.): Known for their intricate, spurred flowers, columbines attract a variety of pollinators, including bees and hummingbirds. They prefer partial shade and well-drained soil.
• Virginia Bluebells (Mertensia virginica): Native to woodland settings, these lovely blue, bell-shaped flowers are a favorite of early spring bees. They thrive in moist, shady conditions and go dormant in summer.

Late Spring/Early Summer Bloomers (Benefiting Young Berry Development)

While honeyberry fruits develop, these plants can support pollinators involved in the later stages of honeyberry fruiting and attract beneficial insects that might prey on potential pests.

• Catmint (Nepeta spp.): Varieties like ‘Walker’s Low’ are long-blooming, drought-tolerant, and highly attractive to bees. They prefer full sun and well-drained soil.
• Lavender (Lavandula spp.): Famous for its fragrance and ability to attract bees and other pollinators, lavender thrives in full sun and well-drained soil.
• Coneflower (Echinacea spp.): These daisy-like flowers are a favorite of butterflies and bees. They prefer full sun and are relatively drought-tolerant once established.
• Salvia (Salvia spp.): Many varieties of Salvia, such as woodland sage, are excellent for attracting bees and have a long bloom period. They generally prefer full sun and well-drained soil.
