As Tsu Dho Nimh said, invasive refers mostly to getting out of control in
undesired places. Unless your water system is extremely old or you're
talking about a septic tank drainage field, "invasive" does not really apply
to this situation.

Hi everybody,

Can anybody help educate me? I want to plant a datura near my front
steps, but
my water line is nearby (within a couple of feet). I have tried to find
info
online about this plant's root system (is it invasive?), but to no avail.
I
certainly don't want to damage my pipes. Can anybody offer advice or
suggest a
site? I'm a gardening newbie and don't want to make any mistakes!

Thanks so much,

Ron
