Why Sweden Wants to Eradicate Lupins, And Why France Doesn’t (Yet)
Introduction
If you've ever admired the tall, vibrant blooms of lupins (genus Lupinus) along the roadside or in a garden, you're not alone. These colorful flowers are beloved by many for their beauty and ability to thrive in tough soils. But in countries like Sweden, they’re not just flowers, they’re a growing ecological concern.
So why is Sweden actively trying to eliminate them, while in France, lupins are still commonly grown and even appreciated? Let’s dive into this environmental contrast.

Sweden’s Battle Against Lupins
1. Invasive Species Threat
Sweden classifies certain lupin species, especially Lupinus polyphyllus (commonly known as the large-leaved lupin), as invasive alien species. Originally imported as ornamental plants, they have since spread into wild ecosystems where they disrupt the native flora and fauna.
These plants are aggressive: they spread quickly, dominate roadsides and meadows, and outcompete native wildflowers, altering entire habitats.
2. Harm to Local Biodiversity
By changing the soil composition, particularly by adding excessive nitrogen, lupins make it hard for nutrient-sensitive native plants to survive. This has knock-on effects for insects, bees, butterflies, and birds that depend on those native species for food and habitat.
Rare flowers like ängsnycklar (a type of wild orchid) have become threatened due to the spread of lupins.
3. EU Regulation Compliance
Lupinus polyphyllus is on the EU list of invasive species of Union concern, which requires member states to control or eradicate the plant. Sweden is taking this responsibility seriously, launching public campaigns and even organizing “Lupin Removal Days” where volunteers help uproot the flowers from nature reserves and roadsides.
4. A Public Awareness Campaign
Sweden has also encouraged homeowners to stop planting lupins in their gardens, even if they are attractive. The goal is to protect biodiversity and support the country’s native species.
What About France?
In contrast, France has not declared lupins as a national invasive threat, at least, not yet.
1. Still Seen as Decorative or Useful
Lupins, including species like Lupinus albus (white lupin), are still widely grown in France:
- As ornamental plants in gardens and public spaces
- As green manure or soil improvers in agriculture
- As a source of plant-based protein for livestock and human consumption
2. Not Yet on France’s National Alert List
While some ecologists have expressed concern about the ecological impact of certain lupin species in sensitive areas (such as parts of the Alps), France has not included them on the national list of invasive alien species requiring control or eradication.
3. Monitoring, Not Removing
Instead of uprooting lupins, France is currently in a stage of monitoring and research. Studies are being conducted to assess whether lupins could have similar ecological consequences as seen in northern Europe.
Comparing Sweden and France
| Aspect | Sweden | France |
|---|---|---|
| Species Considered Invasive | ✅ Lupinus polyphyllus | ❌ Not officially invasive nationally |
| Government Eradication Policy | ✅ Yes – active removal efforts | ❌ No national eradication plan |
| Legal Restrictions | ✅ Under EU Invasive Species Law | ⚠️ Only general monitoring |
| Common Uses Today | 🚫 Discouraged, even in gardens | ✅ Commonly used in gardens & farms |
| Public Campaigns | ✅ National awareness initiatives | ❌ Not a priority issue currently |
Final Thoughts
This striking contrast between Sweden and France reveals how countries respond differently to environmental threats, even within the same continent. While Sweden sees lupins as a danger to biodiversity that must be controlled, France continues to enjoy their benefits, at least for now.
As climate conditions shift and more data becomes available, France may eventually follow Sweden’s lead. Until then, travelers and nature lovers will continue to see lupins blooming across French fields and gardens, a beautiful flower with a complicated future.
