Rare plant alert!

Region: Conservation status by state

Status: S3T1: Status is uncertain but is somewhere between the following rankings: Subspecies or variety is critically Imperiled: Extremely rare due to factor(s) making it especially vulnerable to extinction. Typically 5 or fewer occurrences or very few remaining individuals (<1,000) ⚘ Vulnerable: Either very rare and local throughout its range, found only in a restricted range (even if abundant at some locations), or factors are making it vulnerable to extinction. Typically 21 to 100 occurrences or between 3,000 and 10,000 individuals ⚘

Manystem Blazingstar: A Rare Utah Endemic Worth Knowing About

Have you ever heard of a plant so rare that it exists in only one state? Meet the manystem blazingstar (Mentzelia multicaulis var. librina), a fascinating perennial herb that calls Utah its exclusive home. While this native wildflower might sound like the perfect addition to your drought-tolerant garden, there’s more to this story than meets the eye.

What Makes Manystem Blazingstar Special?

Manystem blazingstar belongs to the blazingstar family (Loasaceae), known for their stunning star-shaped flowers that seem to glow in desert sunlight. As a perennial forb, this plant lacks woody stems but returns year after year from its root system. Like other members of its family, it’s perfectly adapted to harsh, arid conditions that would challenge most garden plants.

Where Does It Grow?

Here’s where things get interesting – and a bit concerning. Manystem blazingstar is found exclusively in Utah, making it what botanists call an endemic species. This extremely limited geographic range is one of the key factors that makes this plant so special, yet so vulnerable.

The Rarity Factor: Why You Shouldn’t Plant This One

Before you start searching nurseries for manystem blazingstar, here’s the important part: this plant has a Global Conservation Status of S3T1, indicating it’s quite rare and potentially at risk. When a plant has such a restricted range and uncertain population status, the responsible thing to do is admire it from afar rather than attempt cultivation.

Removing plants from wild populations or purchasing from questionable sources can further threaten already vulnerable species. Plus, since this variety is so specialized to specific Utah conditions, it likely wouldn’t thrive in gardens outside its native range anyway.

Better Blazingstar Alternatives for Your Garden

Don’t worry – you can still enjoy the magic of blazingstars in your landscape! Consider these more widely available native alternatives:

  • Desert blazingstar (Mentzelia laevicaulis) – spectacular large flowers
  • Small-flowered blazingstar (Mentzelia micrantha) – delicate and charming
  • Ten-petal blazingstar (Mentzelia decapetala) – dramatic evening blooms

These alternatives offer similar drought tolerance and stunning flowers while being more appropriate for garden cultivation.

The Conservation Message

Manystem blazingstar serves as a perfect example of why we need to protect native plant diversity. These rare endemics often hold unique genetic information and play specialized roles in their ecosystems. By learning about plants like this one, we become better stewards of our natural heritage.

If you’re passionate about rare plants, consider supporting botanical research organizations or habitat conservation groups in Utah instead of trying to grow them yourself.

What You Can Do Instead

Rather than attempting to grow manystem blazingstar, channel that enthusiasm into:

  • Growing other native Mentzelia species appropriate for your region
  • Supporting local native plant societies
  • Participating in citizen science projects that monitor rare plants
  • Creating habitat for native pollinators in your garden

Sometimes the best way to appreciate a rare plant is to protect it in its natural home while celebrating its more common cousins in our gardens. Manystem blazingstar may be too special for our flower beds, but that’s exactly what makes it worth protecting.
