The german one is only an annual, so could be harder to keep growing unless you have a nice light soil which would enable self-seeding. I would go for the perennial roman personally. Anthemis nobilis, or Chamaemelum nobile. However, you may get more flowers from the annual variety - I suppose it depends on how much space you are willing to dedicate to it.
Don't buy treneague - that is the non-flowering lawn variety! Also a roman perennial.
Thought this might amuse some of you!
