Eastwood’s Desertparsley: A Rare Colorado Native Worth Protecting in Your Garden

If you’re looking to add a truly special Colorado native to your garden, Eastwood’s desertparsley (Lomatium eastwoodiae) might just be the hidden gem you’ve been searching for. This charming perennial forb brings delicate beauty and important ecological benefits to the right garden setting, though its rarity means you’ll need to be thoughtful about how you acquire it.

Meet This Colorado Endemic

Eastwood’s desertparsley is a perennial herbaceous plant that belongs to the carrot family (Apiaceae). As a forb, it lacks woody tissue and dies back to ground level each winter, emerging fresh each spring from its perennial root system. You might also see it listed under its synonym Aletes eastwoodiae in older botanical references.

This plant is exclusively native to Colorado, where it grows naturally in the western and southwestern regions of the state. Its limited range makes it a true Colorado endemic – you won’t find it growing wild anywhere else in the world!

Why Consider Eastwood’s Desertparsley?

There are several compelling reasons to include this native in your Colorado garden:

  • True Colorado heritage: As a state endemic, it represents the unique botanical character of Colorado
  • Pollinator magnet: The small yellow umbel flowers attract native bees, beneficial wasps, and other important pollinators
  • Low maintenance: Once established, it’s drought tolerant and requires minimal care
  • Unique aesthetic: Offers delicate, feathery foliage and charming clusters of tiny yellow flowers
  • Conservation value: Growing it helps preserve genetic diversity of this rare species

Important Rarity Considerations

Before you rush to plant this beauty, here’s something crucial to know: Eastwood’s desertparsley has a Global Conservation Status of S3S4, indicating it’s uncommon to fairly uncommon throughout its range. This means you should only plant it using responsibly sourced material – never collect from wild populations, and only purchase from reputable native plant nurseries that propagate their own stock or source ethically.

Growing Eastwood’s Desertparsley Successfully

This Colorado native thrives in USDA hardiness zones 4-7, making it well-suited for most of the state’s growing conditions. Here’s what you need to know for success:

Ideal Growing Conditions

  • Sunlight: Full sun exposure
  • Soil: Well-draining soil is absolutely critical – this plant cannot tolerate wet feet
  • Water: Drought tolerant once established, requiring minimal supplemental watering
  • Elevation: Naturally adapted to higher elevations typical of western Colorado

Perfect Garden Settings

Eastwood’s desertparsley shines in:

  • Native Colorado plant gardens
  • Rock gardens and alpine-style plantings
  • Xerophytic (drought-tolerant) landscapes
  • Naturalized areas that mimic native habitat
  • Pollinator gardens focused on native species

Planting and Care Tips

Success with this native comes down to mimicking its natural habitat:

  • Drainage is king: Amend heavy soils with coarse sand or gravel to improve drainage
  • Fall planting works best: Seeds benefit from natural cold stratification over winter
  • Be patient: Like many natives, it may take time to establish but will be long-lived once settled
  • Minimal fertilization: Native soils are typically low in nutrients, so avoid over-fertilizing
  • Respect its dormancy: Allow the plant to naturally die back in winter

Supporting Pollinators and Wildlife

The small yellow flowers of Eastwood’s desertparsley may look modest, but they’re powerhouses for supporting native pollinators. The umbel-shaped flower clusters provide easily accessible nectar and pollen for smaller native bees and beneficial wasps that are crucial for ecosystem health.

The Bottom Line

Eastwood’s desertparsley offers Colorado gardeners a chance to grow a truly unique piece of their state’s natural heritage. While its rarity means you’ll need to source it responsibly, the reward is a beautiful, low-maintenance native that supports local pollinators and connects your garden to Colorado’s distinctive ecological character. Just remember – excellent drainage and patience are your keys to success with this special endemic plant.
