The Honeyberry Shrub: An Underrated Gem for Permaculture Design
In the pursuit of creating resilient, productive, and ecologically sound food systems, permaculture practitioners constantly seek out plants that offer a multitude of benefits. Among the many valuable species, the honeyberry shrub (Lonicera caerulea), also known as haskap or Haskap berry, stands out as a particularly promising addition to any permaculture design. This hardy, adaptable, and incredibly nutritious fruit-bearing shrub offers a compelling combination of features that align perfectly with permaculture principles, from its low maintenance requirements and soil-building capabilities to its early spring blooming and delicious, antioxidant-rich fruit.
What is Honeyberry?
Honeyberry is a deciduous shrub native to the boreal forests of the Northern Hemisphere, including regions of North America, Europe, and Asia. It belongs to the honeysuckle family (Caprifoliaceae), but unlike its ornamental relatives, the honeyberry produces edible, oblong, blue-purple berries in early summer. These berries are characterized by their tart-sweet flavor, often described as a blend of blueberry, raspberry, and plum. Modern cultivars have been developed and extensively bred, particularly in Russia and Japan, to enhance fruit size, yield, and flavor, making them increasingly popular for both commercial and home garden cultivation.
Honeyberry in Permaculture: Aligning with Core Principles
Permaculture, at its heart, is about working with nature, not against it. This philosophy emphasizes observation, mimicry of natural ecosystems, and the creation of closed-loop systems that minimize waste and maximize resource efficiency. The honeyberry shrub naturally fits into this framework due to several key characteristics:
- Perennial Nature: As a long-lived shrub, honeyberry eliminates the need for annual replanting, reducing labor and resource input. This perennial nature contributes to soil structure and fertility over time.
- Nitrogen Fixation (Potential): While not as efficient as legumes, some species of Lonicera have been observed to host nitrogen-fixing bacteria in their root nodules, potentially contributing to soil fertility in mixed plantings. Further research is ongoing in this area for specific honeyberry cultivars.
- Early Blooming and Pollinator Support: Honeyberry is one of the earliest plants to bloom in spring, often flowering while other plants are still dormant. This provides a crucial early nectar source for bees, bumblebees, and other beneficial insects emerging from overwintering.
- Drought Tolerance: Once established, many honeyberry varieties exhibit remarkable drought tolerance, requiring less supplemental watering than many other fruit bushes, a key consideration in water-scarce environments.
- Cold Hardiness: Honeyberry shrubs are exceptionally cold-hardy, capable of surviving temperatures well below freezing. This makes them suitable for a wide range of climates, including those with harsh winters.
- Adaptability: They can thrive in a variety of soil types, although they prefer well-drained, slightly acidic to neutral conditions. They can tolerate partial shade but produce the most abundant fruit in full sun.
- Minimal Pests and Diseases: Honeyberry is generally resistant to most common garden pests and diseases, further reducing the need for chemical interventions.
- Fruit Production and Nutrition: The berries are packed with antioxidants, vitamins (especially Vitamin C), and fiber, offering significant nutritional benefits. Their unique flavor profile makes them versatile for fresh consumption, jams, jellies, pies, and juices.

Integrating Honeyberry into Permaculture Zones
Permaculture design categorizes areas of a landscape based on the frequency of human intervention and the intensity of use. Honeyberry’s adaptability makes it suitable for various zones:
- Zone 1 (Near the home): For easy harvesting and observation, especially for its early blooms that support the first pollinators.
- Zone 2 (Orchards, food forests): Planted as an understory or companion plant to larger fruit trees, benefiting from their shade in hotter climates and contributing to a diverse edible ecosystem.
- Zone 3 (Field crops, larger plantings): Where larger quantities can be grown for processing and preservation. Its resilience makes it ideal for less intensively managed areas.
- Zone 4 (Managed forest, foraging areas): As a robust native or naturalized species that can thrive with minimal intervention, contributing to wild food availability and ecological health.
Designing with Honeyberry: Key Considerations and Steps
Successful integration of honeyberry into a permaculture garden requires thoughtful planning. Here’s a breakdown of essential considerations and steps:
1. Site Selection and Preparation
- Sunlight: While honeyberry tolerates partial shade, optimal fruit production occurs in full sun (at least 6-8 hours per day).
- Soil: Honeyberry prefers well-drained soil. If your soil is heavy clay, consider amending with compost and organic matter, or planting on raised beds or berms. They are not overly fussy about pH, tolerating a wider range than blueberries.
- Water: Ensure the planting site has adequate drainage. While drought-tolerant once established, consistent moisture during the first year is crucial for establishment.
2. Planting and Spacing
- Cross-Pollination: This is perhaps the most critical factor for successful honeyberry fruiting. Honeyberry plants require cross-pollination to produce a good yield. This means planting at least two different varieties that bloom at the same time. While some newer cultivars have improved self-fertility, planting multiple varieties is still the most reliable method.
- Spacing: Plant honeyberry shrubs 4-6 feet apart, depending on the mature size of the chosen cultivars. If interplanting with other species, provide adequate space to prevent overcrowding and allow for air circulation.
3. Planting Procedure
Step | Description |
---|---|
1. Dig the Hole | Dig a hole that is at least twice as wide and as deep as the plant’s root ball. |
2. Amend the Soil | Mix the excavated soil with generous amounts of compost and aged manure. If your soil is heavy, add perlite or coarse sand for improved drainage. |
3. Prepare the Plant | Gently loosen any circling roots on the root ball. If the plant is in a container, remove it carefully. |
4. Position the Plant | Place the plant in the center of the hole, ensuring the top of the root ball is level with or slightly above the surrounding soil. |
5. Backfill the Hole | Fill the hole with the amended soil, gently firming it around the roots to eliminate air pockets. |
6. Water Thoroughly | Water the newly planted shrub deeply to settle the soil and ensure good root-to-soil contact. |
7. Mulch | Apply a 2-3 inch layer of organic mulch (wood chips, straw, compost) around the base of the plant, keeping it a few inches away from the trunk to prevent rot. |
4. Ongoing Care and Maintenance
- Watering: Water regularly during the first year, especially during dry spells. Once established, honeyberry is quite drought-tolerant but benefits from watering during prolonged dry periods, particularly when fruit is developing.
- Fertilizing: Honeyberry plants generally do not require heavy fertilization. A top dressing of compost annually in spring is usually sufficient. If growth is slow, a balanced organic fertilizer can be applied.
- Pruning: Honeyberry is relatively low-maintenance in terms of pruning. The primary goals are to:
Remove any dead, damaged, or crossing branches.
Thin out overly dense canopies to improve air circulation and light penetration.
Remove older, less productive wood (typically 5-7 years old) to encourage new growth.
Pruning is best done in late winter or early spring before new growth begins.
- Pest and Disease Management: As mentioned, honeyberry is largely pest and disease resistant. Birds can be an issue as the fruit ripens, so netting may be necessary if protecting a large harvest.

- Windbreaks and Shelterbelts: Due to its density and cold hardiness, honeyberry can be incorporated into windbreak designs, offering an edible harvest while improving microclimates.
- Living Fences: Planted closely, honeyberry can form a dense, thorny (depending on cultivar) barrier that is both functional and productive.
Companion Planting with Honeyberry
When designing permaculture guilds, consider companion plants that benefit from or contribute to the honeyberry’s growth:
- Nitrogen Fixers: While honeyberry may contribute, pairing it with classic nitrogen fixers like lupines or clovers can further enhance soil fertility.
- Dynamic Accumulators: Plants like comfrey can help bring up nutrients from deeper soil layers, which the honeyberry can then utilize.
- Beneficial Insect Attractors: Planting herbs like borage, thyme, and calendula nearby can attract a wider range of beneficial insects that help with pollination and pest control.
- Shade Tolerant Groundcovers: In areas with partial shade, shade-tolerant groundcovers like wild strawberries or creeping thyme can help suppress weeds and retain soil moisture.
Cultivar Selection for Permaculture Gardens
The vast number of honeyberry cultivars available, primarily from Russian and Canadian breeding programs, means there’s a variety suited to most needs. When selecting cultivars for a permaculture design, consider:
- Ripening Time: Mix early, mid, and late-season varieties for an extended harvest.
- Flavor Profile: Sample different varieties if possible to find flavors that are most appealing.
- Plant Size and Habit: Choose varieties that fit your available space and design goals.
- Self-Fertility: While most benefit from cross-pollination, some newer cultivars show increased self-fertility. Research specific cultivar needs.
- Disease Resistance: While generally hardy, some cultivars may have superior resistance to specific regional issues.
Popular cultivars often cited for their vigor and fruit quality include ‘Northline’, ‘Smoky’, ‘Indigo Gem’, ‘Aurora’, and ‘Borealis’ (from Canada), and various Russian cultivars such as ‘Cinderella’, ‘Honey Bee’, and ‘Tundra’.
