 Native perennial in the Iris family, not a true grass like the common name would suggest.

Plants are pest resistant and somewhat unpalatable to herbivores.  This vigorous cultivar quickly expands into dense spreading clumps that are broader than they are tall.

In garden situations, plants persist for a longer time if they are divided every 2-3 years to promote vigor.  Thick mulch layers should be avoided as this can cause crown rot. 

If seedlings are a problem, shear plants back after flowering to remove developing seed capsules.
