Do the right thing. Don't plant invasive species.
Your State D.N.R. should have a website with a list of Noxious weeds and Invasive Species. If English Ivy is listed as a noxious weed in your state, it is illegal to cultivate it. If it is listed as invasive species, then there will varying restrictions on its cultivation as well. The plants are usually listed in Latin first, so look for Hedera helix or English Ivy.
Micheal Dirr says of Hedera helix that it is "invasive at times, and may smother an entire woodland floor."
To pretend that the damage caused by invasive species is some sort of environmentalist conspiracy theory ignores the devastating economic impact that invasive species can have. 3 quick examples:
#1) Asian carp have migrated up the Mississippi from Arkansas and are now only a few miles away from entering the Great Lakes via the Chicago River. The Army Corp of Engineers has erected an electric barrier across the river to prevent the carp from migrating into the world's largest body of fresh water. Economic impact from loss of game fish species in the Great Lakes has been projected at 100s of billions of dollars, should Asian Carp enter the Great Lakes.
#2) A homeowner at a local condo association got the bright idea to introduce Yellow Floating Heart into 2 retention ponds. Within 2 years, both ponds were covered. The state D.N.R. caught wind and forced removal (drain ponds, dredge bottom, bury spoils, line, refill) for many 10 of thousands of dollars. The threat? Lake Delavan, one of southeast Wisconsin's premier game fish lakes, was a few 100' away. If Yellow Floating Heart has entered the lake, remediation would have cost 100s of millions of dollars. That's one person's actions having the potential to cause millions of dollars in damages.
#3) European Buckthorn was introduced to this country 100 years ago as a quick growing, impenetrable hedge. It has migrated across the country, displacing countless acres of vegetation and the animal species that relied on them. The economic impact of European Buckthorn's introduction to the U.S. is incalculable.
Then there is Purple Loosestrife, Emerald Ash Borer, and Norway Maples. The list is endless.
People want to believe that they have the right to plant whatever they want in their yard, but acting on that perceived personal right can have dire economic and environmental impacts.
Do the right thing. Don't plant invasive species.
