Viper's bugloss honey is a monofloral honey from the nectar of Echium plantagineum and E. vulgare - known as blue borage in New Zealand and viborera in Iberia - produced in New Zealand, Iberia, Australia, and the UK.
Echium plantagineum and Echium vulgare — viper's bugloss in Britain and Ireland, Paterson's Curse and Salvation Jane in Australia, viborera in Spain and Portugal, blue borage in New Zealand's honey trade — are the source plants for one of the world's more widely produced commercial monoflorals. The honey is pale gold to water-white, smooth, slowly crystallizing, with a gentle floral character that has made it a staple of the New Zealand specialty trade and the Mediterranean tablelands. The plant's common name traces to Dioscorides: echis is Greek for viper, and the plant's spotted stems and viper-headed seed cases were thought to indicate (and treat) snakebite under the medieval doctrine of signatures.
Echium plantagineum and the related Echium vulgare are bristly, deep-rooted, blue-purple-flowered plants in the borage family (Boraginaceae). They are native to parts of the European Mediterranean and have naturalized aggressively across temperate Australia, New Zealand, parts of South Africa, and pockets of North America — a global distribution that has produced one of the more interesting cross-naming traditions in commercial honey.
The names trace the plant's reception across regions:
The honey is pale gold to nearly water-white, with a viscous body, gentle floral character on the palate, and unusually slow crystallization for a light-amber monofloral. New Zealand blue borage and Iberian viborera are the most commercially recognized varietal jars; UK production is small-scale beekeeper-direct; Australian Paterson's Curse honey is significant in volume but moves largely through bulk and blended channels rather than as a featured monofloral.
Echium plants, like other members of the Boraginaceae family (borage, comfrey), contain pyrrolizidine alkaloids (PAs) in their leaves and stems. PAs are a class of plant secondary metabolites with documented hepatotoxic and genotoxic potential at concentrated chronic doses; regulatory bodies (FSANZ in Australia/New Zealand, EFSA in the European Union) have published assessments and exposure-limit guidance for PA-containing foods, including some honeys.
Unlike most plant chemistry, PAs do transfer from Boraginaceae floral nectar into the honey in measurable quantities, particularly when the bloom is strongly dominated by a single PA-producing plant. Honeys from heavy Echium monofloral flows have been the subject of analytical chemistry surveys in NZ, Australia, and Europe; concentrations vary substantially with the floral mix and the regional plant population. Commercial Echium monofloral honey remains a legal and widely sold product in producing countries, with regulatory frameworks setting maximum levels and labeling requirements where they apply.
The honest framing for this page: PAs are a real, documented topic in Echium honey chemistry; we don't make a safety claim in either direction. We don't recommend pretending the topic doesn't exist; we also don't practice fearmongering. If PA exposure is a particular concern for you (during pregnancy, with documented liver conditions, for chronic high-volume honey use), check the relevant FSANZ / EFSA guidance and source through producers and importers who can document analytical PA levels in their batches. For occasional culinary use at normal food quantities, the consumer-trade reality across the producing countries is that Echium monofloral honey is sold and consumed without specific labeling restrictions in most markets.
This is the same plant-vs-honey discipline applied across our pages, applied with the unusual complication that here the floral chemistry does carry through to the honey — so the page is correspondingly more careful with what it does and doesn't claim.
Viper's bugloss honey is a gentle, balanced, light-floral monofloral — the palate matches the pale gold color, with no dominant aromatic character pulling against the floral lead.
A balanced light-floral profile — gentle character with no dominant aromatic pulling against the floral lead.
Viper's bugloss is unusual on the global honey shelf for the breadth of its commercial production under the breadth of its trade names — and for an honest plant-vs-honey conversation that most varieties don't need to have.
Viper's bugloss in the UK and Ireland; Paterson's Curse and Salvation Jane in Australia (the same plant under opposite cultural framings); viborera in Iberia; blue borage in the New Zealand honey trade. Few monoflorals carry that breadth of regional naming, which traces the plant's naturalization arc across continents.
New Zealand blue borage honey is a substantial commercial monofloral category, with formal varietal labeling and dedicated producer attention. NZ's Echium populations produce dependable summer flows in particular regions (the central North Island and parts of the South Island), and the resulting honey is one of the most-traded pale-gold monoflorals on the global market.
The "viper" naming runs back through Dioscorides to the medieval European herbal tradition that a plant's appearance signaled its medicinal use — the spotted bristly stems and viper-headed seed cases were the "signature" that supposedly indicated the plant would treat snakebite. The naming has no relationship to modern pharmacology, but it is one of the more visible surviving traces of the doctrine-of-signatures logic in modern commercial nomenclature.
Unlike most varieties, where the plant's pharmacology stays cleanly separate from the honey, Echium's pyrrolizidine alkaloids do transfer into the floral nectar. The disambiguation block on this page handles that factually — no claims either direction, references to FSANZ/EFSA where they apply, and clear framing that the commercial honey trade in producing countries treats Echium monofloral as a normal-foods category.
If you produce viper's bugloss honey— or know a beekeeper who does — we'd love to add them to the directory and surface their jars to readers who arrive here looking for the real thing.

Yes — they are two trade names for the same plant-source honey. The plant is Echium plantagineum (and the closely related E. vulgare); "viper's bugloss" is the UK and Irish common name (and the etymology source — echis is Greek for viper); "blue borage" is the New Zealand honey trade's preferred name. They also share the trade with "Paterson's Curse" and "Salvation Jane" (Australia, used for the same plant under opposite cultural framings) and viborera (Iberia).
Gentle floral on the entry, with a soft caramel-and-light-herbaceous middle and a clean finish. Pale gold to water-white in color; viscous body; unusually slow crystallization for a light-amber monofloral. The character is balanced rather than assertive — closer to acacia or to a mild clover than to a strongly aromatic monofloral.
It is sold and consumed as a normal-foods commercial product in the producing countries (New Zealand, Australia, Spain, Portugal, UK). The relevant nuance is pyrrolizidine alkaloids (PAs), a class of plant secondary metabolites that exist in Echium leaf and stem tissue and that — unlike most plant chemistry — do transfer in measurable quantities into the floral nectar. Regulatory bodies like FSANZ and EFSA have published exposure-limit guidance for PA-containing foods including some honeys. For occasional culinary use at normal food quantities, the commercial trade treats Echium monofloral as a normal-foods category. For more careful situations (pregnancy, documented liver conditions, chronic high-volume honey consumption), sourcing through producers who can document analytical PA levels is a reasonable step.
Because the plant has naturalized across several continents and each region developed its own naming. The UK and Ireland use "viper's bugloss" from the Greek etymology via Dioscorides. Spain and Portugal use viborera by the same viper logic. Australia uses both "Paterson's Curse" (after the early colonist whose property the plant first spread on, with the negative framing of pastoralists who fought its invasiveness) and "Salvation Jane" (the beekeepers' and droughttolerant-ranchers' counter-name). New Zealand's honey trade uses "blue borage" — emphasizing the borage-family relationship and the blue color rather than the snake imagery. Same plant; the names trace the plant's reception history across cultures.
New Zealand is the largest dedicated specialty producer under the "blue borage" trade name. Spain and Portugal produce Iberian viborera monofloral at smaller commercial scale. Australia produces large volumes of Paterson's Curse honey, but much of it moves through bulk and blended channels rather than as featured monofloral. UK production is small-scale beekeeper-direct from chalk-downland and other UK habitats where the native E. vulgare persists.
Indefinitely when stored properly. Room temperature, dark cupboard, lid tight. The honey crystallizes more slowly than most light-amber monoflorals (high fructose content), so liquid-state shelf life is longer than for clover or canola. When eventual crystallization does happen, warm in a bowl of warm tap water for 10–15 minutes to re-liquefy. Never microwave.
