The Sweet Science of Companion Planting with Honeyberries
As urban gardens shrink, the art of maximizing space and benefit becomes paramount. Honeyberry shrubs (Lonicera caerulea), also known as Haskaps, are increasingly popular for their delicious, nutrient-rich berries and their resilience. However, the true magic of a thriving small garden lies in intelligent companion planting. This strategy involves selecting plants that benefit each other through improved soil health, pest deterrence, pollination attraction, and, of course, aesthetic appeal. For honeyberry enthusiasts in urban settings, finding the right flowering companions can transform a functional planting into a vibrant, productive, and beautiful micro-ecosystem.
Choosing companion plants for honeyberries isn’t just about filling empty space; it’s about creating a synergistic environment. Honeyberries, while relatively low-maintenance, can benefit from plants that attract beneficial insects, suppress weeds, or even improve soil structure. Furthermore, in a small urban garden, every plant needs to earn its keep, contributing to the overall beauty and ecological function of the space. This guide will explore a range of flowering plants that not only complement your honeyberry shrubs visually but also offer practical advantages, helping you cultivate a flourishing urban oasis.
Understanding Honeyberry Needs: The Foundation for Companion Selection
Before diving into specific companion plants, it’s crucial to understand the basic needs of honeyberry shrubs. This knowledge will guide our choices and ensure we’re selecting companions that genuinely enhance, rather than compete with, our honeyberries.
Sunlight and Soil Preferences
Honeyberries thrive in full sun to partial shade. While they can tolerate less sun, berry production and plant vigor are best in at least six hours of direct sunlight daily. They prefer well-drained, slightly acidic to neutral soil (pH 5.5-7.0). While they are adaptable, consistently waterlogged soil can lead to root rot.
Pollination Partners
Most honeyberry varieties require cross-pollination from a different cultivar to produce fruit. This means you’ll likely have at least two different honeyberry varieties planted. The flowers themselves, typically small and tubular, are attractive to early-season pollinators like bees. Companion plants that extend the pollinator season and attract a diverse range of bees, butterflies, and other beneficial insects are highly desirable.
Nutrient Requirements
Honeyberries are not heavy feeders, but they benefit from moderately fertile soil. Compost and well-rotted manure are excellent soil amendments. Companion plants that can fix nitrogen or improve soil structure can be advantageous, especially in potentially depleted urban soils.
Key Facts: Honeyberry Shrubs vs. Potential Companion Plants

Its drought tolerance is a significant advantage in urban settings where watering may be managed carefully. While lavender prefers slightly alkaline soil, it can adapt to slightly acidic conditions if amended with a little lime. Its aromatic foliage is also thought to deter certain pests.
Salvia (Salvia spp.)
With a vast array of colors and forms, salvias are champions of continuous blooming. From upright spikes to more mounding varieties, salvias bloom from late spring well into fall, offering a consistent food source for pollinators. Many varieties are drought-tolerant and thrive in full sun, making them ideal companions for honeyberries. They attract a wide range of beneficial insects, including bees, butterflies, and hummingbirds.
Bee Balm (Monarda spp.)
Also known as Bergamot, bee balm is a magnet for bees, butterflies, and hummingbirds. Its unique, shaggy flowers come in vibrant shades of red, pink, and purple. Bee balm prefers consistent moisture but can tolerate drier conditions once established. It enjoys full sun to partial shade, making it a versatile companion. Some gardeners report that bee balm can help deter powdery mildew, a common issue for some plants.
Coneflower (Echinacea purpurea)
These iconic prairie flowers are not only beautiful with their daisy-like blooms but are also highly beneficial for attracting pollinators. Bees, butterflies, and even beneficial wasps are drawn to coneflowers. They are relatively drought-tolerant and thrive in full sun, making them a low-maintenance addition. Their sturdy stems also provide a landing platform for insects.
Herbal Helpers and Edible Enhancements
Incorporating herbs not only adds to the ecological benefits but also provides culinary rewards and attractive blooms.
Chives (Allium schoenoprasum)
These delicate purple pom-pom flowers are a delight for both the eyes and the palate. Chives are known to deter common garden pests like aphids and Japanese beetles, offering a natural form of pest control for your honeyberries. They are easy to grow in full sun and prefer well-drained soil, aligning well with honeyberry needs. The foliage is also edible, providing a mild oniony flavor for your kitchen.
Borage (Borago officinalis)
Borage is a fantastic, fast-growing annual with beautiful star-shaped blue flowers that are edible and taste faintly of cucumber. It is a powerful attractant for bees, often considered one of the best bee attractors available. Borage has a deep taproot that can help break up compacted soil and bring up nutrients. It self-seeds readily, so you’ll likely have it return year after year. It prefers full sun and moist, well-drained soil.
Calendula (Calendula officinalis)
Also known as Pot Marigold, calendula offers bright orange and yellow daisy-like flowers that bloom prolifically from spring to fall. These flowers are edible and have medicinal properties. Calendula attracts beneficial insects like hoverflies, which prey on aphids. It is easy to grow from seed and prefers full sun. Its cheerful blooms provide a burst of color throughout the growing season.
Aesthetic Allies
Sometimes, the best companion is one that simply looks good and complements the natural beauty of the honeyberry shrub.
Coreopsis (Coreopsis spp.)
With its cheerful yellow, daisy-like flowers, Coreopsis adds a sunny disposition to any garden. Many varieties are long-blooming and drought-tolerant once established. They attract pollinators and are generally unfussy about soil conditions, thriving in full sun. Their bright color provides a lovely contrast to the greens and blues of developing honeyberries.

Consider planting lower-growing companions like chives or calendula at the base of your honeyberry shrubs. Taller companions like Salvias or Coneflowers can be planted slightly further out or to the sides, adding vertical interest. This creates a layered effect, maximizing visual appeal and utilizing vertical space efficiently.
Color and Texture Combinations
Think about how the colors and textures of your companion flowers will complement the foliage and eventual berries of your honeyberry shrubs. The vibrant blues and purples of lavender and salvia can create a beautiful contrast with the green leaves. The sunny yellows of Coreopsis add a cheerful pop. The delicate textures of bee balm and astilbe can provide a softer, more romantic feel.
Sustainability in Practice
Many of the suggested companion plants are drought-tolerant and attract beneficial insects, contributing to a more sustainable and resilient garden. By reducing the need for chemical pesticides and supporting natural pest control, you create a healthier environment for both your plants and local wildlife. Choosing native or well-adapted species further enhances this sustainability.
Common Pitfalls to Avoid
While companion planting is beneficial, there are a few common mistakes to steer clear of.
Overcrowding
Ensure there is adequate space between your honeyberry shrubs and their companions. Overcrowding can lead to poor air circulation, increased disease risk, and competition for light, water, and nutrients.
