Re: Re:Invasive-was Background plantings for Shade

Good point, Jaime....in my reply to Anelle, I should have made that
distinction!  So much depends on where in the world you garden.  What is
hard to grow one place is a menace in another part of the globe.  But, I do
think people shouldn't just ban a plant they've never grown because someone
says it is invasive or aggressive.  What one has to do is learn as much as
possible about a plant before inviting it home.  Learning about plants, and
especially about where they originate, also helps figure out whether they
will like our gardens in the first place, saving grief and gnashing of
teeth.
