I have a 1 gal. blooming pot of that alstroemeria sitting in front of the rose and yes, it does work, will get planted soon. I will be buying more of that one to scatter around, it's an almost year round bloomer.
Thanks Marilyn for the other color suggestions, I will be getting that new arilbred Arabian Archer in this summer, it looks like it would be a good compliment. That rose is such a strong dominant color, I figured to just try matching up the beards with that rose may work, maybe a bit of of something yellow. I think Toronto may work too.
and the others you mentioned, (Bronze Sculpture is missing it's tag, need to find it), I agree, good contenders!
Here is the iris I have one one side of the rose now, mentioned earlier.
