Rare plant alert!

Region: Conservation status by state

Status: S5T1T3: 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) ⚘ Subspecies or variety is 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. ⚘ Secure: At very low or no risk of extinction in the jurisdiction due to a very extensive range, abundant populations or occurrences, with little to no concern from declines or threats. ⚘

Big Sagebrush (Artemisia tridentata xericensis): A Rare Native Shrub Worth Knowing

If you’re passionate about native plants and have a special interest in rare subspecies, you may have come across Artemisia tridentata xericensis, a unique form of big sagebrush. This perennial shrub represents one of nature’s more elusive treasures, with a story that’s both fascinating and important for conservation-minded gardeners to understand.

What Makes This Plant Special

Artemisia tridentata xericensis is a native perennial shrub that belongs to the big sagebrush family. Like its relatives, it’s a multi-stemmed woody plant that typically grows to be less than 13 to 16 feet tall, though it usually stays much smaller under normal conditions. What sets this subspecies apart is its extremely limited distribution and rarity status.

Where You’ll Find It (Or Won’t)

This particular subspecies of big sagebrush has an incredibly restricted native range, currently documented only in Idaho. Its limited geographical distribution makes it quite different from the more widespread big sagebrush varieties that carpet much of the American West.

A Word of Caution: Rarity Matters

Before we dive into growing this plant, there’s something important you need to know. Artemisia tridentata xericensis has a Global Conservation Status of S5T1T3, indicating it’s quite rare. This rarity status means that if you’re interested in growing this plant, you should only source it responsibly from reputable native plant nurseries or conservation programs. Never collect seeds or plants from wild populations, as this could harm already vulnerable native stands.

Should You Grow It in Your Garden?

The decision to grow this rare subspecies isn’t one to take lightly. Here are some considerations:

  • Conservation value: Growing rare native plants can contribute to conservation efforts when done responsibly
  • Availability: Due to its rarity, finding nursery-grown specimens may be extremely challenging
  • Specialized needs: Limited information is available about its specific growing requirements
  • Responsibility: You’ll be stewarding a rare piece of Idaho’s natural heritage

Growing Conditions and Care

Unfortunately, detailed growing information specific to Artemisia tridentata xericensis is quite limited due to its rarity and restricted range. As a perennial shrub native to Idaho, it likely prefers the arid conditions typical of sagebrush habitats, but without more specific research on this subspecies, providing detailed care instructions would be speculative.

If you’re interested in supporting sagebrush ecosystems in your garden, consider working with local native plant societies or conservation organizations who might have experience with this particular subspecies or can recommend similar, more readily available native alternatives.

The Bottom Line

Artemisia tridentata xericensis represents the fascinating diversity within our native plant communities, even among closely related subspecies. While its rarity makes it an unlikely choice for most home gardens, its existence reminds us of the incredible biodiversity waiting to be discovered and protected in places like Idaho’s unique ecosystems.

For most gardeners interested in supporting native sagebrush species, exploring more common varieties of Artemisia tridentata might be a more practical starting point, while still contributing to important native habitat restoration efforts.
