Growing Haskap (Honeyberry) in Cold Climates Zone 3–5 / H6–H8

If you only add one new berry to your cold climate garden this year, make it haskap. It is the hardiest, lowest-maintenance, and earliest-fruiting berry you can grow, and most northern gardeners have never heard of it.

Haskap (also called honeyberry in the US) is native to the boreal forests of northern Eurasia and Canada. It has been grown for centuries in Russia, Japan, and Scandinavia, and it is perfectly adapted to exactly the conditions that challenge most other fruit crops – deep winter cold, slow springs, and short summers. While your strawberries are still weeks away from ripening, haskap is already ready to pick.

This is the berry I am adding to my own northern Norway garden this coming season, and this guide covers everything you need to know to get started.

Quick facts: – Hardy to Zone 2 / H8 – tolerates -45°C without any winter protection – First berry to ripen in the season, typically early June in Zone 3–5 – Requires two compatible varieties for cross-pollination – Exceptionally pollinator-friendly – one of the earliest nectar sources in spring – Low maintenance once established, productive for 30+ years – Tolerates a wide range of soil types – no acidification needed

What Is Haskap – and Why Does It Belong in Every Cold Climate Garden?

Haskap (Lonicera caerulea / Lonicera kamtschatica) is a deciduous fruiting shrub in the honeysuckle family. It is native to boreal forests across the Northern Hemisphere, including regions of Canada, Russia, Japan, and parts of the United States. Haskap berries offer a complex, tangy-sweet flavor often described as a cross between a blueberry, a raspberry, and a black currant.

The two names – haskap and honeyberry – refer to slightly different varieties of the same species. The name haskap indicates varieties that are a type of Japanese blue honeysuckle, while honeyberry is the commercial name used for Russian and Kuril varieties. Russian cultivars are generally better suited for growing in colder, higher elevations, whereas Japanese types are well suited to regions where summers can be hot. For Zone 3–5 and H6–H8 gardeners, Russian-origin and Canadian-bred varieties are the best starting point.

Honeyberries grow best in Zones 2, 3 and 4. They need a cold winter dormancy each year. They are cold hardy, fast-growing and tolerant of poor soil. This makes haskap uniquely suited to northern gardens where blueberries struggle with soil pH requirements, and where other berries require more careful winter management.

One often overlooked benefit: haskap is exceptionally valuable for pollinators. The flowers appear very early in spring – often before most other garden plants have even broken dormancy – giving bumblebees and honeybees one of their first nectar sources of the year. In northern gardens where early-season pollinator food is scarce, this makes haskap a genuinely useful addition beyond its fruit.

Step 1: Understand Why Cross-Pollination Is Non-Negotiable

This is the single most important thing to understand before you buy haskap plants. Haskap flowers are self-incompatible and a second compatible plant is needed for fruit to produce from the flowers. As a general rule of thumb, you need one pollinizer plant for every five plants to be pollinated.

Two requirements must both be met for successful pollination:

1. Genetic compatibility – not all varieties can pollinate each other. Closely related varieties share incompatibility genes that prevent successful fruit set even when planted together.

2. Overlapping bloom time – both varieties must flower at the same time. Haskap varieties are categorised into five bloom periods: very early, early, mid, late, and very late. A very early and an early haskap will overlap about 75% of the time, but a very early and a late blooming haskap usually will not overlap at all.

The practical rule: always buy varieties in confirmed compatible pairs. Do not assume two different haskap varieties will pollinate each other – check compatibility before purchasing.

Step 2: Choose the Right Varieties

For Zone 3–5 / USA and Canada

These University of Saskatchewan varieties are the most widely tested and available for cold North American climates:

Variety	Type	Hardy to	Notes
Aurora	Primary	Zone 2–3	Sweet flavor, mid-early season. The most popular variety – plant as main crop
Borealis	Primary	Zone 2–3	Reliable producer, good flavor, slightly smaller than Aurora
Tundra	Primary	Zone 3	Firm berries, excellent flavor, good for hand picking
Boreal Beast	Primary	Zone 3	Very large berries, mid-late season
Boreal Beauty	Primary	Zone 3	Late season, pairs with Boreal Beast
Boreal Blizzard	Primary	Zone 3	Berries are more than twice as heavy as Tundra or Borealis – very large, meaty fruit USask Fruit Program
Honey Bee	Pollinator	Zone 2–3	Selected specifically as a pollinator for Borealis, Tundra and the Indigo series. Very fast growing, productive and starts fruiting at an early age USask Fruit Program
Indigo Gem	Pollinator/Primary	Zone 2–3	Long flowering season, good cross-pollinator for multiple varieties
Indigo Treat	Primary	Zone 2–3	Good flavor, reliable producer

Recommended pairs for Zone 3–5 home gardens:

• Aurora + Tundra – classic combination, excellent flavor from both
• Aurora + Honey Bee – Honey Bee is the most reliable pollinator for Aurora
• Boreal Beast + Boreal Blizzard – large berries, extended harvest window
• Borealis + Indigo Gem – reliable and widely available

Aurora is long, mid-early season flowering. Plant it with other early or mid-types like Honey Bee, Tundra, Berry Blue, or Borealis. Boreal Blizzard, Boreal Beast, and Boreal Beauty are all mid to late-blooming and good partners for cross-pollination with one another.

For Nordic countries and Northern Europe (H6–H8)

Haskap is native to northern Eurasia and has been grown in parts of Scandinavia and Eastern Europe for centuries. Russian-origin varieties are best suited to the H6–H8 climate – they are adapted to cold winters and cool summers, and do not suffer summer stress the way some Japanese varieties can in warmer zones.

In Norway and the Nordic countries, haskap is increasingly available through specialist nurseries and online suppliers. Look for varieties from the University of Saskatchewan breeding programme – Aurora, Tundra, and the Boreal series are all well-tested in climates comparable to H6–H7. Russian-origin varieties such as Berry Blue also perform reliably in northern European conditions.

⚠️ Important for gardeners in Norway and the Nordic countries

Not all haskap varieties are approved for planting in Norway and the EU. An older variety of blue honeysuckle (Lonicera caerulea) is blacklisted in Norway due to its invasive potential in native ecosystems – several municipalities are actively working to remove established plants.

The modern cultivated varieties bred for garden production – sold under the species name Lonicera kamtschatica – do not spread in the wild and are fully approved for sale and planting in Norway and the EU. These were approved as food plants in 2019.

When buying haskap plants in Norway or the Nordic countries, purchase only from reputable nurseries that explicitly stock the modern, approved varieties. If in doubt, ask before you buy.

Step 3: Choose the Right Location

Haskap is more forgiving about location than most berries, but a few principles significantly improve results.

Full sun is strongly preferred in Zone 3–5 and H6–H8 gardens. Honeyberries prefer full sun if you are in a Northern climate in Zones 2–4. In cold northern gardens with short summers, maximising sun exposure directly improves yield and fruit quality. Avoid exposed, windy positions – the early spring flowers are visited by pollinators when temperatures are still low, and a sheltered spot encourages better pollinator activity.

Good air drainage matters more than most gardeners realise. Because haskap blooms so early, it is best to plant in areas with good air drainage and avoid frost pockets. The flowers appear earlier than almost any other garden plant – and although they are remarkably frost tolerant, a severe late frost in a cold hollow can damage an early bloom.

Soil flexibility is one of haskap’s greatest advantages. Honeyberries are not picky about soil type. They have been known to do well on clay soils where other crops have failed. Under ideal conditions they grow in loam with a pH of about 6.5, but they do not require particularly deep or fertile soils. This is a major practical advantage over blueberries, which require acidic soil that many northern gardens cannot provide without significant amendment.

Step 4: Plant Correctly

When to plant

Plant haskap in early spring as soon as the soil can be worked – or in autumn before the ground freezes. Dormant plants require cold weather establishment. Plant in full sun, in well-draining soil amended with ample amounts of organic material.

How to plant – step by step

1. Dig a hole two to three times the size of the root ball.

2. Plant with the top of the root ball no more than 2.5 cm (1 inch) below the natural soil surface. The crown must remain above soil level.

3. Remove grass and competing weeds from a 60 cm (2 ft) circle around each plant.

4. Water thoroughly immediately after planting.

5. Apply 5–8 cm (2–3 inches) of compost or mulch over the root zone. Honeyberries are shallow-rooted, with the majority of their roots in the top 12–18 cm of soil. Weeding and cultivating the topsoil around their base can damage their roots. Mulch suppresses weeds without the need for cultivation close to the plant.

6. Prune stems back by at least one third immediately after planting to encourage new growth.

Spacing

Space plants 120–150 cm (4–5 ft) apart. For best pollination, plant compatible varieties alternating in the same row so bees can easily move between them. If you want to grow haskap as a hedge, plants can be spaced as close as 50 cm (20 inches) apart.

Can haskap be grown in containers?

Yes – haskap adapts well to container growing, which makes it accessible for gardeners with limited space, paved gardens, or balconies. Use a container with a minimum volume of 20 litres per plant to give the root system adequate room. Ensure excellent drainage and water more frequently than you would for in-ground plants, as containers dry out faster.

Choose a sheltered, sunny position – container plants are slightly more exposed to temperature fluctuations than in-ground plants during severe winters, so positioning against a south-facing wall provides useful additional protection in Zone 3 / H7–H8.

Step 5: Ongoing Care

One of haskap’s greatest advantages is how little it needs once established. It is genuinely one of the lowest-maintenance berry crops available to cold climate gardeners.

Watering

Keep soil consistently moist during the first season while the root system establishes. After establishment, haskap is reasonably drought tolerant but benefits from consistent moisture during flowering and fruiting. Aim for approximately 2.5 cm (1 inch) of water per week during the growing season. Honeyberries do not tolerate heavy, wet clay soils or standing water.

Fertilising

Haskap has modest nutrient requirements. The best approach is a handful of compost or a balanced organic fertiliser worked gently into the soil surface around each plant in early spring. Avoid high-nitrogen fertilisers – these encourage leafy growth at the expense of fruit production and can burn the shallow root system. Because of their shallow roots, fertiliser is taken up quickly – less is more.

Pruning

Minimal pruning is needed for the first three years. Remove dead or damaged wood, and thin crowded growth after year three to improve airflow and light penetration. Fruits are produced on one-year-old wood – avoid removing too much new growth when pruning. The best time to prune is late February or March, before new growth begins. Do not prune while the plant is actively growing or when berries are developing.

No winter protection needed

Unlike strawberries, haskap requires no winter mulching or crown protection in Zone 3–5 and H6–H8. The University of Saskatchewan varieties are winter cold hardy to -45°C, and flowers have been known to survive and set fruit after withstanding -11°C temperatures.This is one of the most practically valuable traits haskap offers northern gardeners – it simply goes dormant, survives the winter without help, and wakes up earlier than anything else in the garden.

Step 6: Harvesting

Haskap is the first berry to ripen in the cold climate garden – typically two to three weeks before strawberries, in early to mid-June in Zone 3–5.

Wait longer than you think

The most important harvesting rule is patience. Berries will look ripe on the outside up to ten days before they are actually ripe on the inside. Berries should be completely purple on the inside and outside before harvesting. Pick one berry and cut it open before harvesting the whole crop, if the inside is still green or pale, wait.

A practical guide used by experienced Nordic growers: leave the berries on the bush for an additional 10–15 days after they appear fully blue on the outside. The exterior colour develops before the interior flavour fully matures – patience at this stage makes a significant difference to the sweetness and complexity of the taste.

How to harvest

Depending on variety, haskap can be harvested by hand-picking or by gently shaking the bush over a container. Firmer varieties like Tundra hold well and pick cleanly by hand. Softer varieties drop more readily when ripe. In some varieties all berries ripen at once, in others they ripen gradually over one to two weeks.

Protect from birds

Haskap ripens early, before most other berries are available, birds find it quickly and can strip a bush within a day. Install bird netting as soon as berries begin to colour. This is not optional in most northern gardens.

Storage

Fresh haskap keeps in the refrigerator for up to two weeks after harvest. For longer storage, freeze immediately – haskap freezes exceptionally well and retains both flavor and color. Use frozen haskap for jam, juice, baking, smoothies, and wine.

Nutrition and Health Benefits

Haskap is one of the most nutrient-dense fruits you can grow. The berries contain high levels of vitamin C, vitamin A, vitamin E, pectin, tannins, and anthocyanins, with antioxidant levels roughly double those of wild blueberries. The anthocyanins responsible for the deep blue-purple color are the same compounds associated with cardiovascular health and anti-inflammatory effects.

In Russia, Japan, and other parts of northern Asia, haskap has been used as a medicinal plant for centuries, both the berries and young leaves were used in traditional practice. Modern nutritional research has confirmed the berries’ exceptional antioxidant profile, and interest in haskap as a functional food crop is growing globally.

What Does Haskap Taste Like?

This is the question most gardeners ask first. The answer is: it depends on the variety and ripeness, but the flavor is uniquely its own.

Fully ripe haskap is sweet-tart, with a complex flavor that most people describe as a cross between blueberry, raspberry, and black currant. Under-ripe haskap is notably more tart and can be off-putting, this is why waiting for full ripeness matters so much.

Some varieties, particularly Aurora, tend toward the sweeter end. Russian-origin varieties and Borealis can be more tart. Honey Bee, the pollinator variety, produces smaller berries with less sweetness, this is normal and expected from a pollinator plant.

Haskap works beautifully for fresh eating, jam, juice, baking, smoothies, ice cream, pie, and wine. The high pectin content makes jam-making straightforward without added pectin.

How Long Before You Get a Harvest?

Patience is required in the first seasons. Haskap bushes might begin to bear scant fruit after one year of planting, but will increase their yield as they grow larger, providing an ample harvest after about three to four years.

A mature haskap bush can produce 2–5 kg of fruit per year, depending on variety and conditions. Growers in Alaska, Yukon and the Northwest Territories find the haskap varieties very suited to their short season with long daylight hours. The same applies to northern Norway and other H6–H8 gardens — the long summer days that define these regions suit haskap exceptionally well.

Personal Notes from My Northern Norway Garden

I have not grown haskap yet — but after researching cold climate berries for this blog, it has moved straight to the top of my planting list for this coming season.

The reasons are straightforward. In Nordland, where winters are long and springs arrive slowly, the idea of a berry that ripens before everything else – that needs no winter protection, tolerates our soils, and produces for thirty years – is hard to ignore. I have grown strawberries, currants, and gooseberries, and all of them have their challenges. Haskap seems designed for exactly this climate.

I am also drawn to how early the flowers appear. In northern Norway, early spring is a difficult time for bumblebees and honeybees – there is little food available. A plant that flowers before almost anything else in the garden and provides a generous early nectar source fits naturally into how I want my garden to work.

I am planning to start with Aurora and Tundra – a well-tested pair with good flavor from both plants. I will document the planting and first seasons here as the experience builds.

FAQ: Growing Haskap in Cold Climates

Do I really need two haskap plants?

Yes, always. Haskap is self-incompatible – a single plant will produce little to no fruit. Always plant at least two varieties with confirmed compatibility and overlapping bloom times.

Can I grow haskap in Zone 5 / H6?

Yes, though Zone 3–4 and H6–H7 are the ideal conditions. Haskap needs cold winter dormancy to thrive. In Zone 5 and the warmer end of H6, choose Canadian-bred varieties like Aurora and the Boreal series for the most reliable results.

Does haskap need acidic soil like blueberries?

No. This is one of haskap’s most practical advantages. It grows well in soil with a pH of 5.5–7.5 – a much wider range than blueberries. In gardens where blueberries have failed due to neutral or alkaline soil, haskap is the natural alternative. For gardeners who want to attempt blueberries despite the soil requirements: Growing Blueberries in Cold Climates – soil pH guide and varieties →

When does haskap ripen?

In Zone 3–5 and H6–H8, expect ripe fruit in early to mid-June – typically two to three weeks before strawberries. This makes it the first fresh berry of the season in cold climate gardens.

How long does a haskap bush live?

With the right pollination partners and proper siting, haskaps produce generous crops for 30 years or more. This makes haskap one of the best long-term investments in a cold climate garden.

Is haskap the same as honeyberry?

The terms are used interchangeably in most contexts. Technically, haskap refers to Japanese-origin varieties and honeyberry to Russian-origin ones – but in practice both names are used for all varieties of Lonicera caerulea in the North American market.

Which haskap varieties are approved in Norway?

Modern cultivated varieties sold as Lonicera kamtschatica are fully approved in Norway and the EU. An older variety of blue honeysuckle (Lonicera caerulea) is blacklisted due to invasive potential. Always buy from reputable nurseries that stock approved modern varieties.

Can haskap be grown in a pot or container?

Yes. Use a minimum container volume of 20 litres per plant, ensure good drainage, and place in a sunny, sheltered position. Container plants need more frequent watering than in-ground plants.
