Hi MadGW,
Loosestrife doesn't appear to be listed. But I understand that the Yellow Loosestrife belongs to the same family as primrose and pimpernel. Again not seeing those names on either side of the list.
I think purple loosestrife, while sounding the same, is of a different plant family.
But I am not seeing these on the list of good or bad! Anyone familiar with these plants?
