Macoun’s Woodroot: An Arctic Native That’s Not for Every Garden

Meet Macoun’s woodroot (Podistera macounii), one of nature’s hardy survivors that calls the frigid landscapes of Alaska and northern Canada home. This perennial forb might not be destined for your typical backyard garden, but it’s absolutely fascinating for those interested in arctic and alpine plant communities.

What Is Macoun’s Woodroot?

Macoun’s woodroot is a low-growing perennial that belongs to the carrot family. As a forb, it’s an herbaceous plant without woody stems, spending its energy on surviving in some of North America’s most challenging climates rather than building up woody tissue. This little survivor has adapted to thrive where most plants simply can’t.

Where Does It Grow Naturally?

This arctic native has quite an exclusive address list. You’ll find Macoun’s woodroot growing naturally in Alaska, Yukon, and the Northwest Territories. It’s perfectly adapted to the short growing seasons and extreme cold of these northern regions, making it a true specialist of arctic and subarctic environments.

Should You Plant Macoun’s Woodroot?

Here’s where we need to have an honest conversation. Unless you’re gardening in zones 1-3 (think northern Alaska or similar climates), Macoun’s woodroot is probably not going to work in your garden. This plant has very specific requirements that are nearly impossible to replicate outside its native range:

  • Extremely cold winter temperatures
  • Short, cool growing seasons
  • Well-drained, often rocky soils
  • Specialized soil microorganisms from arctic regions

For the Brave Arctic Gardeners

If you happen to live within this plant’s natural range and want to try growing it, here are some considerations:

  • Provide excellent drainage – soggy soils are a death sentence
  • Mimic natural rocky or gravelly conditions
  • Avoid fertilizing – these plants are adapted to lean, nutrient-poor soils
  • Be patient – arctic plants grow slowly
  • Source plants responsibly from reputable native plant suppliers

Alternative Native Plants

For most gardeners, especially those in more temperate climates, consider these native alternatives that offer similar ground-covering qualities:

  • Wild ginger (Asarum canadense) for shaded areas
  • Wintergreen (Gaultheria procumbens) for acidic soils
  • Wild strawberry (Fragaria virginiana) for sunny spots

The Bottom Line

Macoun’s woodroot is an incredible example of plant adaptation to extreme environments, but it’s not practical for most gardens. Its highly specialized requirements make it a plant best appreciated in its natural habitat or perhaps in specialized botanical collections with controlled arctic conditions. If you’re passionate about native plants, focus on species that are actually native to your region – they’ll be much more likely to thrive and support your local ecosystem.

Sometimes the most responsible thing we can do as gardeners is admire certain plants from afar and choose natives that are better suited to our specific growing conditions.
