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. ⚘

Parry’s Rabbitbrush: A Hidden Gem for High-Elevation Native Gardens

If you’re looking for a tough, drought-tolerant shrub that brings late-season color to your garden, Parry’s rabbitbrush (Ericameria parryi var. affinis) might just be your new best friend. This native beauty is like that reliable friend who shows up when everyone else has given up – blooming brilliantly in fall when most other plants are calling it quits for the year.

What Makes Parry’s Rabbitbrush Special

Parry’s rabbitbrush is a perennial shrub that typically grows as a multi-stemmed woody plant, usually staying under 13-16 feet tall (though most specimens are much more compact). What sets this variety apart is its silvery-gray foliage that provides year-round interest, topped off by clusters of cheerful yellow flowers that appear in late summer and fall.

You might also see this plant listed under its former scientific names, including Chrysothamnus parryi var. affinis, but don’t let the name changes fool you – it’s the same reliable performer regardless of what botanists decide to call it.

Where It Calls Home

This native gem naturally occurs in Colorado and New Mexico, where it thrives in high-elevation montane and subalpine environments. It’s perfectly adapted to the challenging conditions found in these regions – think intense sun, dramatic temperature swings, and limited water availability.

Why Your Garden Will Love It

Parry’s rabbitbrush isn’t just another pretty face in the garden – it’s a workhorse that brings multiple benefits:

  • Late-season pollinator magnet: When most flowers have faded, this shrub provides crucial nectar for bees, butterflies, and other pollinators preparing for winter
  • Drought champion: Once established, it laughs in the face of dry spells
  • Low maintenance: Perfect for gardeners who want beauty without the fuss
  • Year-round interest: Attractive foliage provides structure even when not in bloom

Perfect Garden Companions

This shrub shines in xeriscapes, rock gardens, and naturalized native plant areas. It’s particularly well-suited for high-elevation landscapes where many other plants struggle. Pair it with other drought-tolerant natives like penstemon, Indian paintbrush, or native grasses for a stunning, water-wise display.

Growing Parry’s Rabbitbrush Successfully

Hardiness: Thrives in USDA zones 4-7, making it perfect for cooler, high-elevation gardens.

Light requirements: Full sun is essential – this plant needs at least 6-8 hours of direct sunlight daily.

Soil needs: Well-draining soil is non-negotiable. It actually prefers alkaline conditions and will struggle in heavy, clay soils that stay wet.

Water requirements: Drought tolerant once established, but young plants will need regular watering their first year.

Planting and Care Tips

  • Plant in spring after the last frost date
  • Space plants 3-4 feet apart to allow for mature spread
  • Water regularly the first year, then reduce to occasional deep watering
  • Minimal fertilization needed – too much nutrition can actually reduce flowering
  • Light pruning in early spring can help maintain shape, but it’s not necessary

A Word About Conservation

Parry’s rabbitbrush has a somewhat uncertain conservation status, so if you’re planning to add it to your garden, make sure you source it from reputable nurseries that use responsibly collected or propagated stock. Never collect plants from the wild – besides being potentially illegal, it can harm already vulnerable populations.

The Bottom Line

If you garden in the right climate zone and can provide the sunny, well-drained conditions this shrub craves, Parry’s rabbitbrush is an excellent choice for adding native beauty to your landscape. It’s particularly valuable for gardeners in Colorado and New Mexico who want to create authentic, regionally appropriate gardens that support local wildlife. Just remember – this isn’t a plant for humid, low-elevation gardens or areas with heavy soil. But in the right spot? It’s absolutely golden.
