gardenfish said:So THATS what it might be. Never seen it in pre-arranged bouquets, though. Is it poisonous to dogs? Good info for all the dog owners out there to have. I'm also thinking about another plant I have seen in those bouquets, can't remember the name of this one either,, old timers disease is a b...h. I am going to Kroger's, I will check out the flowers there and see if there are any fillers like this.
I actually grew this plant this year.
It's a very well-behaved "grass". It can take bog conditions and remains strongly upright even after intense wind.
I can't find any specific info on whether or not it's toxic, but it's in the well-known sedge grass family, so I'm guessing if it was very toxic we'd know about it. Most toxic principles in a plant are concentrated in their stems or bulbs anyway, and a dog would have to eat a significant amount of that to reap the symptoms.
