Yes, many plants crossed the oceans in ship ballast or by other accidental 
means, but Purple Loosestrife was brought here on purpose as a garden plant. 
Some of our most notorious invasives were imported as ornamentals.  In 
addition to Purple Loosestrife, they include Amur Honeysuckle, Japanese 
Honeysuckle, Euonymus fortunei, Tree of Heaven, Crown Vetch and Kudzu. Crown 
Vetch was primarily spread by highway departments for erosion control and 
Kudzu was used as a forage plant, but both were also widely grown in gardens. 
The point is that these plants and many others were intentionally introduced, 
we grow them in our gardens and they have escaped cultivation and are causing 
serious environmental problems.  --Janis
