Blue Honeysuckle Seeds (Honeyberry) – Lonicera caerulea

Blue Honeysuckle (also called Honeyberry or Haskap) is a cold-hardy fruiting shrub prized for its early harvest and blueberry-like flavor. These Lonicera caerulea seeds are suitable for growers in cooler climates and for anyone who wants a resilient berry bush that tolerates a wide soil pH and needs less fuss than blueberries.

Why Choose Blue Honeysuckle?

• Cold-hardy, early fruiting shrub – well-suited to colder regions and late-spring harvests
• Adaptable to soil pH – performs in a wider pH range than blueberries
• Compact habit – typically 3–6 ft mature height, easy to fit into home gardens
• Flavorful berries – often described as blueberry-meets-raspberry; excellent fresh or for jam
• Growing zones – generally USDA Zones 2–7 (variety-dependent; some sources note broader ranges)

What’s in the Pack?

Fresh, clean Blue Honeysuckle (Lonicera caerulea) seeds in a sealed pack. Seeds may vary genetically; seedlings do not always grow identical to named cultivars.

Planting Instructions

• Best Time to Start: Late winter to early spring after stratification, or sow outdoors in fall.
• Stratification: Cold-moist stratify 60–90 days at ~4°C. Optional method for stubborn lots: 60 days warm-moist (≈21–30°C) followed by 60 days cold-moist.
• Soil: Well-drained, moderately fertile; typical pH tolerance ~5.5–7.5 (tolerates wider than blueberries).
• Light: Full sun in cool climates; in warmer zones, morning sun with light afternoon shade improves performance.
• Sowing Depth: Cover lightly, about 3–6 mm (⅛–¼ in). Keep evenly moist—not waterlogged.
• Germination: After stratification, expect emergence in ~4–8 weeks (can be variable).
• Spacing (after transplant): 3–4 ft between plants; 6–10 ft between rows (hedge spacing is also used).
• Pollination: For fruit set you’ll need at least two different honeyberry varieties with overlapping bloom.
• Growing Zone Note: Commonly grown in USDA Zones 2–7; check your local climate/chill hours.

FAQs

Is this seed or a live plant?

Seed. These are Blue Honeysuckle seeds (not live plants or plugs).

Do I need two plants to get fruit?

Yes. Most honeyberries require cross-pollination between two different varieties that bloom at the same time for reliable fruit set.

Will seedlings grow true to a named cultivar?

Not necessarily. Seed-grown honeyberries can vary from the parent cultivar. Many growers start several seedlings and later keep the best performers or add a named cultivar for pollination.

Do the seeds require cold stratification?

Recommended. Provide 60–90 days of cold-moist stratification (refrigerator method). For harder seed lots, a warm-then-cold sequence can improve results.

What growing zones are suitable?

Generally USDA Zones 2–7 (variety-dependent; some sources cite a broader 1–8/2–8 range). In warmer zones, provide morning sun and protection from harsh afternoon heat.
