Are Trilliums Protected in Michigan?

Key Takeaways

  • Four trillium species are endangered or threatened in Michigan.
  • Picking threatened or endangered trilliums may be illegal.
  • All trilliums except White trillium are protected in Michigan.
  • Trillium undulatum is endangered in Michigan.
  • It's legal to pick unthreatened trilliums on private property.


Trilliums are spring-blooming wildflowers that can be found throughout many forests in Michigan. Their unique blossoms and resilience through the long winter make them a beloved sign of spring. However, some trillium species are rare or endangered in Michigan. This raises an important question – are trilliums protected by law in the state?

This article will provide a comprehensive overview of trillium protection laws and regulations in Michigan. Understanding the conservation status of different trillium species can ensure ethical enjoyment of these wildflowers. We'll cover which species are endangered or threatened, where picking trilliums may be illegal, and exceptions that allow collecting certain trilliums. After reading, you'll have a full understanding of trillium protection in Michigan.

Protecting vulnerable plant species ensures healthy, biodiverse forests for generations to come. Learning about responsible ways to appreciate trilliums enables both ethical recreation and conservation. A thorough knowledge of regulations allows trillium enthusiasts to admire these woodland gems while still safeguarding rare types.

Trillium Species Protected in Michigan

Michigan's natural resources agency, the Department of Natural Resources (DNR), oversees conservation of plant species in the state. The DNR has assigned protected status to some trillium species under the Endangered Species Act of Michigan. This law makes it illegal to harm species designated as endangered or threatened.

Four trillium species have protected status in Michigan:

  • Trillium flexipes (Drooping Trillium) – Threatened
  • Trillium nivale (Snow Trillium) – Threatened
  • Trillium recurvatum (Prairie Trillium) – Threatened
  • Trillium undulatum (Painted Trillium) – Endangered

These species are vulnerable to habitat loss and damage from picking or digging up the plant. The endangered designation means Trillium undulatum is at high risk of extinction in Michigan with only a few surviving populations.

Threatened status indicates the species could become endangered without continued protection. Restrictions on harming or removing these plants aim to prevent further decline.

Is it Illegal to Pick Protected Trilliums?

It is illegal to knowingly harm, collect, or sell any threatened or endangered species in Michigan. This includes the four protected trillium species. Violating the Endangered Species Act carries penalties of up to 90 days jail time or fines up to $5,000.

However, incidental damage is not necessarily illegal. For example, trampling a few trilliums while hiking through the woods would not violate the law. But intentionally picking or digging up protected trilliums could be illegal take of an endangered plant.

Trilliums also have protected status in certain designated locations:

  • Trillium cernuum (Nodding Trillium) – Threatened in Michigan's Upper Peninsula
  • Trillium catesbaei (Bashful Trillium) – Threatened in southern Lower Peninsula

It would be illegal to remove these trillium species from these locations. So it's important to check regulations for the area you plan to visit.

Are Common Trilliums Protected?

Trillium grandiflorum, the showy white trillium, does not have any special conservation status in Michigan. This common species is not covered by the Endangered Species Act.

However, the DNR notes white trillium takes many years to reach maturity and produce flowers. They advise only picking common trilliums sparingly from robust populations. Never harvest trilliums from public lands.

All trillium species besides white trillium have some protection under Michigan's Endangered Species Act. But regulations only apply to plants in their native habitat.

For example, it is legal to cultivate trilliums you purchased from a nursery in your home garden. You can also pick trilliums legally on private land you own, as long as the species is not classified as threatened or endangered in that region.

Why Are Trilliums Protected?

Trilliums play an important ecological role in Michigan forests. As spring wildflowers, they supply an early source of nectar for pollinators like bees and butterflies after winter dormancy.

Many woodland animals also rely on trilliums. Bears dig up and eat the energy-rich rootstocks. Mice and voles nibble on trillium leaves and seeds. White-tailed deer browse trillium foliage.

Slow maturation makes trilliums especially vulnerable to overpicking. It can take 7 to 16 years for a trillium seedling to produce its first flower. The plant relies on its rootstock for energy between flowering seasons. Digging up trilliums destroys the whole organism.

Habitat loss is another major threat. Trilliums depend on high quality undisturbed forests with rich soil. Rampant deer populations can also overbrowse trillium populations.

Legal protection aims to prevent vulnerable trillium species from declining to the point of extinction. Preserving trillium diversity strengthens Michigan's woodland .

Tips for Responsible Trillium Viewing

Here are some tips for ethically viewing or collecting trilliums in Michigan:

  • Research regulations for your location and avoid threatened or endangered species.
  • Always harvest trilliums extremely sparingly. Never dig up the plant.
  • Pick common trilliums only on private land with the owner's permission.
  • Take only photographs when visiting public lands like state parks.
  • Stay on trails to avoid trampling trillium colonies.
  • Share locations of rare trilliums only with other responsible wildflower enthusiasts.
  • Volunteer with organizations like the Michigan Botanical Club to help survey and preserve populations.


In summary, Michigan extends legal protection to some rare or vulnerable trillium species. It is illegal to harm or collect the four threatened or endangered trilliums in Michigan. While common trilliums have no official protected status, responsible harvesting is still vital for conservation.

Understanding regulations on collecting trilliums enables people to safely admire them. With care, Michigan's woodlands will continue to display a tapestry of trillium diversity each spring for generations to come.
