What Makes the Inyo Rockdaisy Special?

Don’t let its small stature fool you—this low-growing shrub packs a lot of personality into its compact frame. Standing barely 1.5 feet tall at maturity, the Inyo rockdaisy produces cheerful white daisy-like flowers with bright yellow centers that bloom from spring through fall. It’s the kind of plant that makes you stop and smile when you spot it tucked into a rocky crevice or spilling over a stone wall.

Where Does It Call Home?

The Inyo rockdaisy is a California exclusive, native specifically to the Eastern Sierra Nevada region around Inyo County. This specialized habitat preference means it’s perfectly adapted to the unique conditions of this high-desert mountain environment.

A Word of Caution: Rarity Matters

Here’s something important every gardener should know: the Inyo rockdaisy has a Global Conservation Status of S2, meaning it’s considered Imperiled. With only 6 to 20 known occurrences and an estimated 1,000 to 3,000 individual plants remaining in the wild, this little daisy is fighting for survival.

If you’re interested in growing this rare beauty, please only use responsibly sourced material from reputable native plant nurseries or seed companies that work with conservation programs. Never collect plants or seeds from wild populations.

Is the Inyo Rockdaisy Right for Your Garden?

This specialized native isn’t for every garden, but it could be perfect for yours if you’re looking to:

  • Create a authentic California native plant collection
  • Design a rock garden or xeriscaped landscape
  • Support local pollinators with native blooms
  • Grow something truly unique and rare

The Inyo rockdaisy thrives in USDA hardiness zones 7-10 and is an excellent choice for gardeners in areas with similar climatic conditions to its native range.

Growing Inyo Rockdaisy Successfully

Think mountain desert when planning for this plant’s needs:

  • Sunlight: Full sun is essential for healthy growth and abundant blooming
  • Soil: Well-draining sandy or rocky soil is crucial—this plant absolutely cannot tolerate soggy conditions
  • Water: Drought tolerant once established, but provide occasional deep watering during extreme dry spells
  • Drainage: Excellent drainage is non-negotiable; consider raised beds or slopes if your soil retains moisture

Wildlife and Pollinator Benefits

Despite its small size, the Inyo rockdaisy pulls its weight in supporting local ecosystems. Its daisy-like flowers attract small native bees, butterflies, and other beneficial insects, making it a valuable addition to pollinator-friendly gardens.

The Bottom Line

While it requires specific growing conditions and responsible sourcing, the reward of successfully cultivating this imperiled beauty makes the effort worthwhile.
