Saltugilia splendens grantii 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. Saltugilia splendens grantii is also known as:

Gilia splendens Douglas ex Mason & Grant ssp. grantii Grant & | USDA symbol: GISPG
Gilia tenuiflora sensu , non | USDA symbol: GITE6
Gilia tenuiflora var. altissima | USDA symbol: GITEA3
Saltugilia grinnellii Johnson ssp. grantii | USDA symbol: SAGRG3

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.
