Before folks get too enamored with weeds that can wreck ecological havoc, take
a look at the following two web pages. the first will take you to a specific
page for spotted knapweed, (which is known to have eliminated local demes of
Karner blues).  This is in no way a beneficial species, even if butterflies do
take nectar from it.

The next link is the searchable database, which will allow you to find
authoritative information on almost all the major wildland weeds that cause
ecological disruption in the US (including Hawaii and Puerto Rico) and adjacent
portions of Mexico and Canada.

Take a close look species before you try and  paint them in a pleasant light.
And note that native milkweeds are not considered by The Conservancy to be
wildland weeds - although other organizations may consider them to be
agricultural pests.
