Re: Invasive or not?

Thanks for the further clarification KK.

I stand corrected.

Although, your clarification does confirm the point I
was (awkwardly) trying to make:

that the plant is listed only as HAVING POTENTIAL to
become invasive or expand or whatever word they use. I
did go to your marked Cal website and there was, sure
enough, a note about the speices.  But it's NOT on any
of their true weed lists.

I didn't try Googling for the Fallbrook Naval Weapons
Station.  But it wouldn't have improved my memory.  I
didn't know it then -- sounds like it's something that
wouldn't have received much publicity, if you know
what I mean.  Now I know.

One of only two plants that I'd ever seen of this
species was, indeed, in north San Diego County.  A
great bollowy specimen on a slope on the east side of
Hwy 5.  It had been there many years when I first saw
it and that was 28 years ago.  I think it's gone now
but during it's many years there, I never saw
seedlings of it nearby.

Believe it or not, I am an avid proponent of watching
out for potential weeds (watch out you sneaky
international-seed-by-mail-or-suitcase people).  

But the reality is, there's an awful lot of plants
that have naturalized locally in many parts of
California.  Perfect conditions, I'm sure, exist
somewhere in this state for almost every Mediterranean
climate plant to become a pest.

Is this really the question Annie is asking?
