Growing Conditions That Make It Happy

Success with Inyo princesplume comes down to understanding its desert origins. This plant has very specific needs:

  • Sunlight: Full sun is absolutely essential

  • Climate: Hardy in USDA zones 4-8
  • Soil quality: Actually prefers poor, rocky soils over rich garden soil

Planting and Care Tips for Success

Getting Inyo princesplume established requires patience and the right approach:

  • Drainage is everything: If your soil doesn’t drain well, consider raised beds or rock gardens
  • Less is more with water: Water regularly the first year to establish roots, then back off significantly
  • Don’t pamper it: Avoid fertilizers and rich soils that can actually harm this desert native
  • Be patient: Like many natives, it may take a season or two to really get going
  • Source responsibly: Purchase from native plant nurseries rather than wild collection

Stanleya pinnata var. inyoensis is also known as...

Often we refer to plants by their common names. When shopping for plants the scientific name is the best way to positively identify the plant species you desire. But some plants have more than one name! While it doesn't happen often, nurseries might display one name while you're searching for another. Stanleya pinnata var. inyoensis is also known as:

Stanleya pinnata Britton ssp. inyoensis Munz & | USDA symbol: STPII3

Why do some plants have more than one name? Over time plant species may be renamed for a few reasons:

  1. Botanists in different regions named the same plant without knowing it had already been classified.
  2. A species was reclassified after scientific advances in, for example, DNA analysis.
  3. Slight variations within a species are sometimes mistakenly identified as entirely new species.
