Preferred Growing Conditions

  • Watering: Water regularly the first season to help establishment, then reduce to occasional deep watering
  • Maintenance: Minimal pruning needed; you can cut back in late winter if desired

Setting Realistic Expectations

While foxtail wheatgrass is wonderfully low-maintenance, it’s worth understanding what you’re getting.

×Pseudelymus saxicola 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. ×Pseudelymus saxicola is also known as:

Agropyron saxicola | USDA symbol: AGSA2
×Agrositanion saxicola | USDA symbol: AGSA5
Elymus saxicola & | USDA symbol: ELSA6

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.
