Important Considerations Before Planting

Responsible Sourcing is Critical! Given its vulnerable status, it’s absolutely essential that you only purchase jeweled blue-eyed grass from reputable native plant nurseries that ethically propagate their plants. Never collect plants from the wild, as this could further threaten wild populations.

Sisyrinchium xerophyllum 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. Sisyrinchium xerophyllum is also known as:

Sisyrinchium solstitiale | USDA symbol: SISO
Sisyrinchium tortum | USDA symbol: SITO

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.
