Re: CULT: alien weed - Cuscuta

Lots of species of dodder (Cuscuta) are native, some not.  It's related
to morning glory, but is parasitic.  Because part of the dodder is
<inside> the host plant, just removing the visible part of the dodder
<vine> won't get rid of it.

I don't know what Roundup and other systemic plant poisons would do -
might be translocated from the dodder to the host plant and kill both.

Only sure disposal method I know is burning - both dodder and host
plant.  Fragments will resprout.

I don't remember ever having it in my garden, but see it occasionally
out in fields.  The species I've seen must not be too successful - never
much of it or in very large patches, & I don't remember seeing it in the
same places from year to year.

Web surf turned up interesting tidbit that it was used in pre-Columbian
times as a dye in Mexico.
