Porter’s Licorice-Root: A Rare Mountain Gem for Specialized Native Gardens

If you’re looking to add something truly unique to your native plant collection, Porter’s licorice-root (Ligusticum porteri var. brevilobum) might catch your attention. This lesser-known variety of the more common Porter’s licorice-root is a fascinating herbaceous perennial that calls the mountain regions of Nevada and Utah home.

What Makes This Plant Special?

Porter’s licorice-root belongs to the carrot family (Apiaceae) and grows as what botanists call a forb – essentially a non-woody perennial herb. Unlike its shrubby neighbors, this plant dies back to ground level each winter and emerges fresh each spring, a strategy that serves it well in harsh mountain conditions.

Where You’ll Find It Growing Wild

This particular variety has a remarkably limited native range, growing naturally only in Nevada and Utah. It’s adapted to high-elevation environments where conditions can be quite challenging – think rocky slopes, mountain meadows, and areas where most garden plants would struggle to survive.

A Word of Caution: Rarity Matters

Before you get too excited about adding this plant to your garden, there’s something important to consider. Porter’s licorice-root variety brevilobum has a conservation status that suggests it’s not particularly common in the wild. This means if you’re interested in growing it, you should only source plants or seeds from reputable native plant nurseries that can guarantee their stock is ethically and sustainably collected.

Never collect this plant from the wild – doing so could harm already limited populations.

Is This Plant Right for Your Garden?

Honestly, this isn’t going to be the right choice for most gardeners. Here’s why:

  • It’s extremely specialized to high-elevation mountain conditions
  • Very limited availability from commercial sources
  • Likely requires specific soil and climate conditions that are hard to replicate
  • Better suited for botanical collections or specialized native plant gardens

Growing Conditions (What We Know)

While specific cultivation information for this variety is scarce, we can make some educated guesses based on its natural habitat:

  • Likely prefers well-draining, rocky or sandy soils
  • Probably needs cool temperatures and good air circulation
  • May require a cold winter dormancy period
  • Suited for USDA hardiness zones that match its native Nevada and Utah mountain regions

Alternative Options

If you’re drawn to native plants from the carrot family or mountain wildflowers, consider these more readily available alternatives:

  • Other Ligusticum species that are less rare
  • Native mountain plants suited to your specific region
  • Locally native members of the Apiaceae family

The Bottom Line

Porter’s licorice-root variety brevilobum is undoubtedly a fascinating plant, but it’s probably not the best choice for most home gardens. Its rarity, specialized growing requirements, and limited availability make it more of a collector’s plant than a garden staple. If you’re serious about growing rare native plants and have experience with challenging species, this could be an interesting addition – but only if you can source it responsibly.

For most gardeners, focusing on more common native plants that provide reliable beauty and ecological benefits will be a better use of time and garden space.
