RE: Iris pseudacorus

 

  • According to http://plants.usda.gov/core/profile?symbol=IRPS this is the status of I. pseudacorus in the U.S., not exactly universally considered a pest. Add New York to the list and you have 14% of the states. Just sayin...
  • Connecticut: Invasive, banned
  • Massachusetts: Prohibited
  • Montana: Category 3 noxious weed
  • New Hampshire: Prohibited invasive species
  • Oregon: "B" designated weed, quarantine
  • Washington: Class C noxious weed

I wonder if the penalty is against the seller or the buyer for I.
pseudacorus in one of those states & provinces.

I lost interest in I. pseudacorus about 15 years ago when I visited a
site in SW Ohio where I. brevicaulis still exists and I. pseudacorus had
completely taken over there. It was sickening to see it choking out
native species. I removed it from my collection entirely. I kept
'Beuron' for a while but it was in too dry a spot & it died out. A few
years ago I received Tsukiyono, a sterile pseudata, as a gift which
bothered me at first, but I'm okay with it now.

Basically, I'm in the anti-pseudacorus camp. I'll never grow it again.
And I roll my eyes so damn hard every time I see it win an award. But
not nearly as hard as I do when a bearded "Spec-x" wins that award. But
that's a whole 'nother story. ;-)
