Well, folks, seeing what purple loostrife is doing to our 'Up North" country; the heartwrenching decimation of forests by imported pests, etc., etc., I say "yes", I am dismayed that catalogs push the already overplanted in place of sturdier natives or "heirlooms". How long before we lose our maples, beeches, birches, firs, etc., to the next undiscovered pest? (Rhetorical question--no need to answer). Personally, any plant beginning with the letter "L" is off my list. Lysmachia, Loostrife (well, Liatris can stay...), you get the picture. All seem to take over anything in their way.
I'm working on some plans for mostly sandy soil (a term used loosely) and find that my available options are limited, according to the federal and state invasive/noxious (love that word!) lists. Well, at least I have a little time before I can work out in the yard, so I can keep hunting.
