I like the look and feel of the seed head and the naturalized look in gardens. So, I'm giving it a cautious positve rating. Will see if it goes crazy, in my gardens.

This is a plant that can spread like wildfire with little or no help. The seeds can remain viable for quite some time and will sprout just when you think you have it all pulled out.

Cattle won't graze on it, so it is a liability as pasture grass. Birds like the seeds, but there are way more seeds to go around than the birds will eat.

It preferrs cultivated fields and is a hinderance to grain farmers.

Florists like the seed heads to use in arrangements, and it is attractive nodding along the roadways, but control of this weed is difficult, and it can adversely affect the environment in some instances.
