	Sisyrinchiums native to  the United States are herbaceous perennials 
and do not produce a rhizome. An iris borer would starve feeding on any 
of these. The only sisyrinchium with a sizable rhizome is S. striatum 
from South America and hardy only to USDA zone 7.

	The common blue eyed grass in my locale is S. campestre. It is never a 
weed here, although it does seed around the garden. It is also known as 
the Prairie Blue Eyed Grass and occurs throughout the central third of 
the USA and into Canada and Mexico. A variant pops up in the state of 
Kansas called Sisyrinchium capestre kansanun. It has lovely white 
flowers and I wish it were more aggressive as I must divide it and care 
for it in order for it to thrive in my garden. Included is a photo 
taken in May of this year. In my zone 5 garden it reaches about 10 
inches.
