I was just informed by the Michigan legislature and locals That these plants listed below and considered invasive and illegal to grow or sell in the state of Michigan. A home gardener can be fined $200 and a comercial grower or landscaper can be fined $2000. There has been much controversy on this subject and hopefully reviewed and changed by 2006
Plants listed under these acts are
Fallopia japonica 'Compacta' Dwarf Japanese Knotweed
Iris pseudacorus 'Variegatus' Variegated Yellow Flag Iris
Iris pseudacorus 'Flora Pleno Double Flowered Yellow Flag Iris
Fallopia Japonica Variegata Variegated Japanese Knotweed
For more information please go to the State of Michigan site and look up
Public acts 74-80

Michigan new law passed growing these plants are illegal
Strange, I've never know iris to be real invasive. ?
Those particular iris are way more than spready when they are happy. I can put one rhizome in a 3 gallon pot each spring and it blows the pot apart by fall. LOL They are pretty though. :)
Can't imagine anything that pretty being illegal;)

Heck its been growing wild in my yard for years(the iris)
along with the purple
was here before I moved here
what is a person suppose to do
Kill it
I heard knot weed is almost impossible
the iris is a pain to dig up when they get huge too
The iris in particular is no invasive at all in garden settings. However, I noticed a thread trading it for ponds in the plant trading forum and the pictures of how "beautiful" they looked as a thick (5 ft maybe) ring around a couple of different ponds on gardener's properties show why it's really important not to plant this thing in the water in a wild setting.
The purple is a native, and is one of the species that the yellow flag will outcompete and displace. I inherited a bunch of yellow flag on my hill in central NY, it behaves like any other iris, though more like Siberian than bearded. But it does tend to grow fast, and if the soil weren't dry and compact (and if I let the seed pods ripen) I'd have a different situation.
It's a shame that a state has to make a ban statewide on a plant that may or may not be invasive across all environments in all parts of a state.. but with the way most people are gardening... It's going to happen all across America.. as the cost for controlling invasives slowly outweighs the clamour of nursery lobbyist and 'gardeners' used to planting things that grow fast and fill in (most species I have in my garden that grow quickly and fill in.. and then spread into other plants... I call weeds).
Sorry about the soapbox, but the information about the yellow flag is accurate according to a friend of mine that just finished a masters in wetlands biology and is now working for NYState in that field.
Well. Learn something new every day around here!! It sounds kinds like Joe Pye weed here. Maybe it looks ok in Mr Jones garden that lives in Way Away From here Town but in my back meadow it absolutely takes over!!

I wish my feet would hold out to dig some of my yellow. They are beautiful but they have outgrown their "space" and are uprooting my stepping stones and spreading into my daylilies. Someone must have told them their was water nearby !!!
