Rare plant alert!

Region: Conservation status by state

Status: S3S4: Status is uncertain but is somewhere between the following rankings: 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 ⚘ Apparently Secure: Uncommon but not rare, and usually widespread. Possibly cause for longterm concern.

Discovering the Rare Alaskan Grapefern: A Hidden Treasure of the North

Meet Botrychium yaaxudakeit, a fascinating and extremely rare grapefern that calls the wilds of Alaska home. While most gardeners will never encounter this elusive native plant in person, it represents an incredible example of botanical diversity in North America’s Last Frontier. This isn’t your typical garden-variety fern – it’s a true botanical treasure that tells a story of Alaska’s unique ecosystems.

What Makes This Grapefern Special

This perennial fern belongs to the Botrychium genus, commonly known as grapeferns or moonworts. Like its relatives, Botrychium yaaxudakeit has a distinctive appearance that sets it apart from typical ferns. Instead of the familiar frilly fronds we usually associate with ferns, grapeferns produce two distinct types of fronds: a sterile leaf for photosynthesis and a separate fertile spike that looks remarkably like a tiny bunch of grapes – hence the grapefern name.

Where This Rare Beauty Lives

Botrychium yaaxudakeit is native exclusively to Alaska, where it grows in very specific and limited locations. This fern represents the incredible botanical diversity that thrives in Alaska’s unique climate and ecosystems, adapted to conditions that would challenge most other plant species.

A Plant for Observation, Not Cultivation

Here’s the important part for gardeners: this rare grapefern has a Global Conservation Status of S3S4, indicating it may be vulnerable or of conservation concern. This means it should absolutely not be collected from the wild, and it’s not available through normal gardening channels – nor should it be.

Additionally, even if it were available, Botrychium yaaxudakeit would be virtually impossible to grow successfully outside its native Alaskan habitat. These specialized ferns require very specific environmental conditions, including:

  • Cool temperatures year-round
  • Specific soil chemistry and mycorrhizal relationships
  • Precise moisture levels
  • Particular seasonal temperature fluctuations

Appreciating Native Ferns in Your Own Garden

While you can’t (and shouldn’t) grow this rare Alaskan treasure, you can celebrate the diversity of native ferns by incorporating locally native species into your landscape. Depending on where you live, consider these alternatives:

  • Christmas fern (Polystichum acrostichoides) for eastern gardens
  • Western sword fern (Polystichum munitum) for Pacific Northwest gardens
  • Cinnamon fern (Osmundastrum cinnamomeum) for woodland gardens
  • Royal fern (Osmunda regalis) for wet areas

The Bigger Picture

Botrychium yaaxudakeit serves as a wonderful reminder of the incredible plant diversity that exists in North America’s wild places. While we may never grow this particular species in our gardens, we can support conservation efforts and appreciate the importance of protecting rare plants in their natural habitats.

As gardeners, we can honor species like this rare Alaskan grapefern by choosing native plants for our own regions, supporting botanical research and conservation efforts, and fostering an appreciation for the amazing diversity of plant life that surrounds us – even if some of it remains delightfully out of reach in the wild places where it belongs.
